Also called: CT surgery, cardiac surgery, thoracic surgery, CTS. Entered either straight from medical school (integrated I-6) or as a fellowship after general surgery. Organ systems: heart, great vessels, lungs, esophagus, mediastinum, chest wall.

The 30-second version

Cardiothoracic surgery is the field that operates on the organs you cannot live without, the heart, the aorta, and the lungs, often while a machine takes over the patient's circulation. A CT surgeon reroutes blocked coronary arteries, repairs or replaces heart valves, rebuilds torn aortas, removes lung and esophageal cancers, and implants pumps and transplanted hearts into people who would otherwise die. It is among the highest-paid work in all of medicine, and it asks the most in return: the longest training path of any specialty, roughly 70-hour weeks, and emergency call that arrives on the aorta's schedule or the donor organ's, never yours. The whole personality of the field is that trade: extraordinary meaning and top-tier pay, bought with more years, more hours, and more consequence-per-decision than almost anywhere else in medicine.

What they actually do

Cardiothoracic surgeons operate inside the chest: on the heart and its valves, the coronary arteries, the aorta and great vessels, and the lungs, esophagus, and mediastinum. The signature cardiac operations are coronary artery bypass grafting (CABG) and valve repair/replacement, frequently performed on cardiopulmonary bypass, a heart-lung machine ("the pump") that oxygenates and circulates the blood while the heart is stopped and worked on. General thoracic surgeons remove lung and esophageal cancers and treat chest-wall and mediastinal disease, increasingly through minimally invasive and robotic approaches. At the extreme end sit heart and lung transplant, mechanical circulatory support (LVADs, ECMO), and complex aortic reconstruction, the highest-acuity work in the specialty.

The core skill is sustained, high-precision operating under conditions where the margin for error is essentially zero and a single misstep can be fatal. It is also, despite the stereotype, profoundly team-dense: safe cardiac surgery is impossible without perfusion, anesthesia, ICU, and nursing all moving in concert.

Representative procedures: coronary artery bypass grafting (CABG) · valve repair and replacement (aortic, mitral) · aortic aneurysm and dissection repair · lung resection (lobectomy, VATS/robotic) · esophagectomy · heart and lung transplantation · LVAD implantation and ECMO cannulation · mediastinal and chest-wall procedures · structural/hybrid heart work alongside interventional cardiology.

A day in the life: Cardiac days often start early with a marathon elective case: a CABG runs 3–6 hours, valve and aortic reconstructions longer, and a complex re-do or transplant can consume most of the day. Between cases there are critically ill ICU patients who can decompensate at any hour, add-on emergencies, and rounds. General thoracic practice is more clinic-and-elective in rhythm, with fewer middle-of-the-night crises. Then there is call, which in cardiac practice is defined by true emergencies that cannot wait: acute aortic dissection, ruptured aneurysm, post-op bleeding or tamponade, ECMO cannulation, and transplant/donor-organ runs. Overnight emergency operations are a normal feature of the job, not an exception.1

The training path & time to completion

CT surgery is unusual: it's one of the few fields you can enter directly from medical school, and also one you can reach the long way after a full general surgery residency. All routes lead to certification by the American Board of Thoracic Surgery (ABTS), and compensation is essentially identical once you're in independent practice, but the pathways differ by years, by how early you must commit, and by how open they are to non-US-MD applicants.2

  • Integrated (I-6): direct entry from medical school into a 6-year CT program, with no separate general surgery residency. Board eligibility is ABTS only. This is the shortest route and the most competitive; it also forces the earliest, most binding commitment (you choose CT as a medical student, before you've explored much else).23
  • Traditional (independent): 5-year general surgery residency, then a 2–3-year CT fellowship (you apply during roughly your 4th general-surgery year) = ~7–8 postgraduate years. Graduates are dual board-eligible (American Board of Surgery and ABTS). Longer, but keeps general surgery as a fallback and lets you decide later.2
  • Fast-track / joint "4+3": 4 years general surgery + 3 years CT at the same institution = 7 years total, with ABS + ABTS eligibility. Note it is institution-locked: only general surgery residents at that same program are eligible for its CT slots.2
  • Congenital/pediatric cardiac requires a dedicated ACGME fellowship after primary CT training, at 24 consecutive months if training began on or after July 1, 2023 (up from the older 12-month standard). Transplant/MCS and aortic work are pursued as further focused fellowships or high-volume practice concentrations.2
  • Board: ABTS, by written (Part I) + oral (Part II) exam.2
  • Total from the start of college: roughly 14–16 years (4 undergrad + 4 med school + 6–8 training), before any congenital or transplant super-fellowship, the longest standard pipeline in medicine.

How competitive is it?

CT surgery is one of the most competitive things you can match into, but the shape of that competition depends entirely on which pathway you mean, and the field's reputation has swung almost 180 degrees in a decade.

The integrated I-6 pathway is a near-closed, US-MD-dominated funnel. In 2026 there were 39 programs, 56 positions and 100% fill, against 110 applicants ranking the specialty, an applicant-to-position ratio of 1.96:1. In 2025 it was 40 programs, 54 positions and 130 applicants, 2.41:1.34 Because so few seats exist, a large minority of US-MD seniors who apply don't match: 52 of 88 matched in 2026, so 41% did not, against 50 of 94 and 47% in 2025.34 ⟳

  • Matched I-6 academic profile: USMLE Step 1 ≈ 244 ± 11, Step 2 CK ≈ 249 ± 13, with ~10.5 publications on average and ~23% having done a dedicated research year (vs. ~6% of unmatched applicants).5 ⟳
  • US MD seniors fill ~90%+ of I-6 seats (52 of 56 in 2026; 50 of 54 in 2025; 45 of 48 in 2024). DO representation is minimal (1 in 2026, 2 in 2025, 1 in 2024) and IMG representation is near-zero (1 US IMG and 2 non-US IMGs in 2026). For practical purposes the I-6 route is near-closed to non-US-MD applicants.34 ⟳
  • I-6 positions have grown from 3 (2007) to 56 (2026), and applications have risen ~150%, outpacing the seat growth, which is why it keeps getting harder.5 ⟳

The traditional fellowship is larger and meaningfully more open. Matched via the NRMP Specialties Matching Service after general surgery: 89 programs / 97 positions, 100% filled in 2025 (83/92 in 2024), from ~165 applicants preferring the specialty. Its matched class in 2025 was 77% MD, ~18% IMG and US-IMG combined, and 3% DO, far more IMG and DO representation than the I-6 route.67 ⟳

The reputation swing you need to know. For years CT surgery was described as a "dying field," on oversupply fears plus interventional cardiology (stents, and later TAVR for aortic valves) displacing open cases. That narrative has reversed: the practicing workforce grew from ~4,000 (2005) to ~5,200 (2021), trainees more than doubled (230 in 2008 to 519 in 2023), the integrated I-6 match has filled every position for several years running (56 of 56 in 2026), and HRSA now projects thoracic surgery to have among the largest workforce shortfalls of any specialty, roughly 31% short by 2035.89 Applicants still repeating the "dying field" line are working from a decade-old story. (More on what that means for pay and jobs below.)

Compensation — the robust version

CT surgery is a top-1/top-2 earning specialty, trading the #1 spot with neurosurgery in the big surveys. But the headline numbers scatter more widely than in most fields, because the surveys measure genuinely different things and the small high-earning surveys have thin samples. A note on sources first: treat Doximity as the broadest adjusted average, FastRVU as a modeled employed-productivity benchmark rather than a licensed survey table, and SalaryDr as a high-skewing self-report panel of 23 physicians: different lenses rather than contradictions.101112

National number. Depending on source and definition, a practicing CT surgeon lands anywhere from ~$530,000 (FastRVU's modeled employed-productivity median) to ~$690,000 (Doximity 2025 adjusted average), with high-volume adult-cardiac and private-group operators well into $1M+. A defensible "typical" range for 2026 is ~$550,000–$800,000 total compensation for most employed surgeons, and $1M–$1.5M+ for established private/high-volume practice.1011 ⟳

  • Doximity 2025 (2024 data): thoracic surgery average $689,969, #2 of all specialties behind neurosurgery ($749,140).10 ⟳
  • FastRVU (an aggregator's own modeled benchmark, not a licensed MGMA table): employed median ~$530,000.11 ⟳
  • SalaryDr 2026: median $1.2M, average ~$1.5M, but n = 23, so treat it as directional only.12 ⟳
  • BLS "Surgeons, All Other" (May 2025): mean $373,930, on a median of $414,010 and a 90th percentile of $655,320, but this is a broad bucket blending many surgical fields; use it as floor and context rather than as a CT-specific figure.13

The spread (structure). FastRVU's modeled productivity → pay ladder: early-career/low-volume (<7,500 wRVU) ~$450k · median ~$530k · high performers (>12,000 wRVU) ~$680k.11 The SalaryDr self-report distribution runs much higher and wider (median $1.2M; 90th pct ~$2.95M; max ~$5.17M) but rests on 23 responses.12 ⟳

Starting vs. experienced, and the late start. ResidencyAdvisor's composite bands put new attendings (0–3 yr) at ~$600k–$900k, established surgeons (5–15 yr) at ~$800k–$1.3M+, and late-career/partners up to $1.0M–$1.5M+ (indicative bands, not per-figure sourced).14 SalaryDr shows a 45% jump from early-career to 10+ years.12 The crucial caveat: unlike shorter fields, that curve starts late, and the leap from a final-fellow salary ($80k) to a first-year attending ($600k+) is enormous, but it doesn't happen until the surgeon's early-to-mid 30s at the earliest (see the FLI angle).14 ⟳

Subspecialty pay varies a lot. Adult cardiac tops the range (drives the $900k–$1.3M+ bands); by MGMA, congenital/pediatric cardiac ~$631,397, cardiovascular transplant ~$505,404, and general thoracic ~$429,923, still very-high-tier but below high-volume adult cardiac.1415 A congenital caveat: peds cardiac carries the longest training and lowest case volume per surgeon (few centers, concentrated caseloads), so despite high per-case complexity, career earnings can lag adult cardiac and the ramp to full practice is the longest of all. ⟳

Geography. By base-salary aggregator ranking, top states include New Jersey, Wisconsin, Washington, Massachusetts, Alaska; lowest include West Virginia and Florida (these are base figures well below total comp, so use them for relative spread only).16 The directional pattern echoes other surgical fields: rural/underserved and many Southern/Midwestern markets pay more (recruitment premiums, less competition), while coastal urban academic centers pay less but offer prestige and case volume. No clean national dollar differential is published.1417 ⟳

Academic vs. private. On ResidencyAdvisor's composite structure, academic base runs ~$450k–$900k+ plus RVU and stipends, with the lower base offset by research, teaching, prestige, and less variable call. Private practice total potential $800k–$1.5M+, commonly $400k–$600k base + productivity bonus. Hospital-employed/health-system roles are competitive-to-slightly-below private but more stable, and are now the dominant model (SalaryDr 2026: 57% hospital-employed).1214 ⟳

How you're actually paid. Productivity-driven: FastRVU's modeled median ~8,900 wRVU/yr (25th 7,200 · 75th 11,000 · 90th 13,500) at ~$60 per wRVU (typical $58–$62).11 Bonus and incentive are a real slice: SalaryDr 2026, a small self-reported panel, puts median bonus at ~$250k, about 15% of total comp, with 74% receiving one.12 Call is heavy and often separately compensated (stipends/per-diem), especially where transplant/ECMO/emergent aortic coverage is required, and niche skills (aortic, LVAD/ECMO, transplant, structural heart) command premiums where centers need them, though no clean national dollar figure exists.14 Reported hours run 72/week ($404/hr equivalent, SalaryDr).12 ⟳

The trend that colors all of it. Doximity's thoracic average slipped from $720,634 (2024 report) to $689,969 (2025 report), a modest year-over-year give-back even as overall physician pay rose ~3.7%, but it held #2.1018 The bigger story is demand: with ~900 surgeons projected to retire, procedural demand rising ~20%, and a ~31% shortfall projected by 2035, driven by structural heart disease, ECMO/MCS, and expanded lung-cancer screening, the workforce backdrop points to strong demand and pricing power ahead, even as TAVR and structural heart continue to reshape rather than shrink the case mix toward complex, redo, multivalve, and aortic work.89 ⟳

Lifestyle & the long-hours bargain

The most-cited reality of CT surgery: the hours and the call are among the hardest in all of medicine. Reported weeks run ~70+ hours (one 2026 self-report pegs the average around 72), at or near the top of the entire field.112 The work itself is marathon-like, with long cases on the pump demanding sustained, high-stakes concentration, and it's stacked on top of critically ill ICU patients and emergency call defined by dissections, ruptures, bleeds, and donor-organ runs that arrive on nobody's schedule.1 Schedule control is low, especially in the early attending years and in cardiac-heavy practices.

But the field is not monolithic. General thoracic practice (lung, esophagus, mediastinum) is more elective and clinic-based, with far fewer middle-of-the-night emergencies, a meaningfully more livable lifestyle than high-volume adult cardiac or transplant/mechanical-support work.1 The lifestyle cost is also front-loaded: the heaviest toll lands during the uniquely long training (6–8 years) and early practice.

Lifestyle rating: 1/5. Among the most demanding lifestyles in medicine: very long hours, heavy high-acuity call, and low control over the calendar, partially relieved only by choosing a general-thoracic-weighted practice or cutting operative volume later in career.

Wellbeing — the part to take seriously

Burnout is high, and so is satisfaction. Both at once. The STS 2019 Member Practice Survey (1,069 surgeons; Ikonomidis et al., Annals of Thoracic Surgery) found ~55.7% reporting symptoms of burnout or depression, yet ~83.1% satisfied, very satisfied, or extremely satisfied with their career choice.19 SalaryDr's 2026 self-report panel echoes the top line: ~91% would choose the specialty again, satisfaction ~4.1/5, on 23 responses.12 This is the field's defining "hardest but most rewarding" paradox: a punishing load carried alongside deep meaning from operating on the heart and great vessels. ⟳

The trainee cost is real. A March 2019 TSRA resident survey found ~60% of CT residents burned out multiple times per month or more, ~44% feeling "down, depressed, or hopeless" in the prior month, and, importantly, ~25.9% who would NOT do the residency again. The meaning does not erase the cost for everyone.20 ⟳

Wellbeing here is also a safety issue. STS reporting links surgeon depersonalization and emotional exhaustion to measurably higher self-reported error rates, one reason burnout in this high-stakes field is treated as a patient-safety concern, not merely a lifestyle one.20

Career longevity is the real question. Two forces shape how long you can do this: the physical demands (long standing cases, fine motor precision, sleep disruption) and the psychological weight of routinely operating where a single misstep can be fatal. Many surgeons migrate toward less-emergent thoracic work, administration, education, or reduced operative volume later in career; reflective essays describe eventually "hanging up" the scalpel with a mix of loss and fulfillment.21

Who's in the field (demographics)

  • Women: ~8.3% of practicing thoracic surgeons (AAMC 2021), one of the least gender-diverse specialties (AAMC's separate 2017 workforce estimate was ~7%; by subspecialty circa 2010, adult cardiac 3.4%, congenital 5.2%, general thoracic 7.9%). The trainee pipeline is markedly higher and rising: I-6 residents were 28.9% women in 2018–2022, up from 24.1% in 2013–2017; fellowship-track 24.6%, up from 19.9%, so the balance is shifting, slowly.2223 ⟳
  • DO: near-zero in the I-6 pathway (1 matched 2024, 2 in 2025, roughly 2–4% of the cohort); ~3% of the traditional fellowship class. Among the least DO-accessible fields.346 ⟳
  • IMG: near-zero in I-6 (0 in 2024; 2 non-US IMGs in 2025), but ~18% (IMG + US-IMG combined) of the traditional fellowship class, so the fellowship route is a real, if narrow, entry point that the I-6 route is not.346 ⟳
  • URiM: no statistically significant change in the share of Black or Hispanic trainees between 2013–2017 and 2018–2022 in either pathway. Women and Black trainees remain significantly under-represented relative to their share of medical-school enrollment; Hispanic representation approximately matched enrollment share. Neither study's abstract gives a per-group percentage.2425 ⟳

Culture, personality & the online stereotypes

Who gravitates here: resilient, high-stakes perfectionists who want to operate on the heart and great vessels and are willing to commit to the longest training in medicine as a long game. People energized rather than paralyzed by cases where the margin for error is essentially zero. Technical mastery, the gravity of the work, and, done right, collaborative team leadership are recurring self-described draws. As always, plenty of people in the field do not fit any single mold.1

The stereotypes. Community caricatures rather than facts, each with an unfair edge:

  • "The ultimate alpha surgeon / god complex." CT surgeons sit atop the online hierarchy of surgical stereotypes, the archetypal ego-driven operator. It's a caricature: it flattens a field full of humble, collaborative surgeons and ignores that operating safely on the heart requires meticulous teamwork with perfusion, anesthesia, and ICU staff, not lone-genius bravado.
  • "You sacrifice your whole life." There's a real kernel, since the hours and training length are genuinely extreme, but as a blanket claim it's an overstatement; general thoracic practice and many attending arrangements are far more livable than the stereotype implies.
  • "It's a dying field." Outdated and now simply wrong: the workforce is projected to be in shortage, and the 2025 match filled 100%. Applicants still repeating this are working from a decade-old narrative.

What people say online (synthesized and paraphrased, not quotes): Across trainee and physician forums the recurring themes are consistent. There's strong consensus that you should only pursue CT if you truly love the operating itself, because the training length and lifestyle punish anyone chasing prestige or money alone. Current posters routinely correct the "dying field" myth, pointing to the shortage, high fill rates, and robust job market. People repeatedly note that lifestyle varies enormously: general thoracic is described as far more livable than high-volume adult cardiac or transplant work. The I-6 pathway comes up often as a way to shave years off training, alongside debate about whether committing straight out of medical school is too early and binding a choice. And there's candid acknowledgment that the culture skews intense and traditionally male, with slowly improving but still low representation of women and minorities.

Voices from the field. Paraphrased from public writing, with links to the originals:

  • A cardiothoracic surgeon argues in an STS blog that the "dying field" story is dead, since the specialty is growing, the 2025 match filled completely, and a ~31% shortfall looms by 2035 as structural heart disease, ECMO, and lung-cancer screening drive demand, while flagging that ~90% of trainees are still male and calling for earlier mentorship and broader recruitment.9
  • John S. Ikonomidis, MD, PhD, reporting the STS 2019 member survey, states the paradox directly: ~83% career satisfaction alongside ~56% burnout/depression symptoms, and urges surgeons to recognize warning signs and act before burnout compromises patient care.19
  • A surgeon reflecting on 40 years in a CTSNet essay frames the deepest fulfillment as mentoring and training the next generation; he acknowledges real personal sacrifice and the bittersweet moment of stopping operating, yet describes a career of lifelong happiness and satisfaction.21
  • The STS News summary of the TSRA resident survey surfaces the trainee cost beneath the satisfaction: ~60% burned out multiple times monthly, ~44% feeling down or hopeless, ~26% who would not repeat the residency, and ties surgeon distress to measurable increases in self-reported errors.20

Why people choose it / why people leave

Why choose it: you operate on the heart, lungs, and great vessels, some of the highest-stakes and most technically demanding work in all of surgery · top-tier compensation · a job market that swung from feared oversupply to genuine shortage · profound meaning and ownership (most CT surgeons would choose the field again despite the toll) · constant innovation (hybrid/structural heart, ECMO/MCS, minimally invasive and robotic thoracic).

Why leave or avoid it: ~70+ hour weeks and heavy high-acuity emergency call with low schedule control · the longest training path in medicine (6–8 years) defers attending income and life milestones the longest · physical demands and the psychological weight of operating where errors can be fatal · high burnout/depression rates · an early, binding career commitment (especially via I-6) before you've explored other fields · near-closed entry for DO/IMG applicants.

Best fit if: you're genuinely energized by long, high-stakes operations and can't picture a career outside the chest · you have the physical and emotional stamina for marathon cases and middle-of-the-night emergencies · you can commit to the long game of training and delayed payoff · you want elite technical mastery and are comfortable owning ultimate responsibility.

Not for you if: predictable hours, schedule control, or the shortest path to attending income matter most · you have significant family or financial caregiving duties that make ~70-hour weeks and 6–8 years of low training pay untenable now · you dislike marathon procedures or high-consequence, time-pressured decisions · you want to keep multiple specialty doors open late into training.

The FLI angle — Cardiothoracic Surgery for first-gen, low-income & immigrant students

Where CT surgery fits FLI realities well:

  • Among the highest pay in all of medicine. A top-1/top-2 earning specialty with an established/private ceiling of $1M–$1.5M+, meaningful long-run security and leverage for someone with no family financial safety net.
  • A now-favorable job market swinging into shortage. With a ~31% projected shortfall by 2035 and an aging workforce, demand and bargaining power look strong for the foreseeable future, valuable if you can't rely on family connections or geographic luck.
  • Demonstrable, high-value technical skill with demand in academic and larger community centers nationwide.

The real risks, named squarely:

  • The longest income deferral in medicine. 6 years (I-6) to 7–8 years (general surgery + fellowship) of training before attending pay, meaning peak earning arrives 10+ years into practice and the whole curve starts later than almost any other field. For a first-gen/low-income student who may be a breadwinner or already has financial caregiving duties, this is the single heaviest CT-specific consideration, because the payoff is large but arrives latest, and years of foregone earnings and compounding are a real cost.
  • The lifestyle is brutal for anyone with caregiving or financial duties now. ~70+ hour weeks and unpredictable emergency call collide directly with caring for children, parents, or a partner who works. This is a concrete, not abstract, tension for FLI applicants who more often carry family obligations peers do not, and it runs across the long training years and early practice, exactly when those duties are heaviest.
  • Near-closed to DO and IMG applicants. The integrated I-6 pathway is one of the most US-MD-dominated, hardest-to-enter routes in all of medicine (near-zero DO/IMG, ~90%+ US-MD seniors), and it rewards research years and publications that presuppose early mentorship and research access, advantages many FLI students never had. The traditional general-surgery→fellowship route is meaningfully more open to DO/IMG (~18% IMG+US-IMG, ~3% DO), so for many FLI applicants it is the more realistic door, at the cost of an even longer path.
  • An early, binding commitment. Choosing I-6 means committing to CT as a medical student, which is harder to do confidently without the shadowing and mentorship FLI students often lack early, so it is worth deliberately seeking CT mentors and OR exposure well before applying.

Bottom line: CT surgery offers FLI students an exceptional financial and job-security ceiling, but demands the longest financial patience, the most punishing lifestyle, and entry into one of medicine's most gate-kept pipelines. It rewards those who can weather a very long deferral and have (or can build) support structures for the training years; it is genuinely risky for those with immediate financial or caregiving duties, or without early access to mentorship and a US-MD track. If you're drawn to it, get into a cardiac OR early, and, if the I-6 door is hard to reach, know the general-surgery-then-fellowship route stays open.

Subspecialties & fellowships

The three principal domains of adult cardiac, general thoracic, and congenital cardiac are joined by focused fellowships and high-volume practice concentrations. Note the lifestyle and pay spread within the field is large.

  • Adult Cardiac Surgery. CABG, valve repair/replacement, aortic surgery; the highest-acuity, heaviest-call, highest-earning core of the field.
  • General Thoracic Surgery. Lung, esophagus, mediastinum, chest wall (much of it cancer); more elective, better lifestyle, growing with expanded lung-cancer screening.
  • Congenital / Pediatric Cardiac Surgery. Repair of complex congenital defects in children; extremely demanding, highly specialized, requires a dedicated 24-month fellowship and carries the longest ramp to full practice.
  • Heart Transplant & Mechanical Circulatory Support (LVAD/ECMO). End-stage heart failure, transplants, and pumps; organ-timed emergencies and intense ICU involvement.
  • Lung Transplant. End-stage lung disease; organ-timed, high-acuity, tertiary-center based.
  • Aortic Surgery. Complex aneurysm and dissection repair; among the most technically formidable and emergent work in the specialty.
  • Minimally Invasive / Robotic Thoracic & Cardiac Surgery. VATS/robotic lung and valve procedures; a fast-evolving, technology-driven niche.
  • Endovascular / Hybrid & Structural Heart. Catheter-based and combined open/endovascular work (TEVAR, TAVR collaboration); increasingly overlapping with interventional cardiology.

Fun facts

  • CT surgery once carried a "dying field" reputation; it now faces a projected ~31% workforce shortage by 2035 and has filled every integrated I-6 position for several years running, 56 of 56 in 2026.49
  • The integrated I-6 pathway lets students enter CT surgery directly from medical school, a relatively new route (3 positions in 2007, 54 in 2025) that compresses training to 6 years.25
  • Thoracic surgery has ranked #2 of all specialties in Doximity's physician compensation report, trading the top spot with neurosurgery.10
  • A single routine CABG runs 3–6 hours; complex aortic and transplant cases can take most of a day.1
  • It's one of the few fields where the "on-call emergency" can be a donor organ becoming available or an acute aortic dissection, events on nobody's schedule.
  • Women remain ~8% of the CT workforce. One of the least gender-diverse specialties, though the trainee pipeline (~25–29%) is well ahead of the practicing share, a gap the field is actively working to close.922

NRMP, Results and Data: 2024 Main Residency Match (June 2024) — Thoracic Surgery (I-6): 34 programs, 48 positions, 100% filled; 114 applicants; US MD 45/80, DO 1/5, US IMG 0/3, non-US IMG 0/16. https://www.nrmp.org/wp-content/uploads/2024/06/2024-Main-Match-Results-and-Data-Final.pdf ↩ ↩2 ↩3 ↩4 ↩5 ↩6

  4. NRMP, Results and Data: 2025 Main Residency Match (May 2025) — Thoracic Surgery (I-6): 40 programs, 54 positions, 100% filled; 130 applicants; US MD 50/94, DO 2/9, US IMG 0/0, non-US IMG 2/19. https://www.nrmp.org/wp-content/uploads/2025/05/Main_Match_Results_and_Data_20250529_FINAL.pdf. The 2026 edition (May 2026, Table 1A and Table 2) reports 39 programs, 56 positions offered and 56 filled, 110 total applicants and 88 US MD senior applicants, of whom 52 matched: 52 US MD seniors, 1 DO senior, 1 US IMG, 2 non-US IMG. https://www.nrmp.org/wp-content/uploads/2026/05/Main_Match_Results_and_Data-2026.pdf Corrected 2026-08-17: the dashboard row carried "~2.4:1 applicants, ~half of US-MD applicants don't match" with no year, and both halves were the 2025 cycle. On 2026 the ratio is 110/56 = 1.96:1 and 52 of 88 US MD seniors matched, so "roughly half don't match" has become roughly two in five. The 2026 report was already cited here and quoted twice in the body; the competitiveness section was simply not carried forward with it. ↩ ↩2 ↩3 ↩4 ↩5 ↩6

  5. Matched I-6 academic profile (Step 1 244±11, Step 2 CK 249±13, ~10.5 publications, ~23% research year) and I-6 growth (3 in 2007 → 54 in 2025, applications +~150%).

  6. NRMP, Match Results Statistics: Thoracic Surgery and Vascular Surgery (April 2025) — traditional CT fellowship (SMS): 89 programs, 97 positions, 100% filled, 165 applicants; matched composition MD 77.3%, US-IMG 10.3%, IMG 8.2%, DO 3.1%, Canadian 1.0%. https://www.nrmp.org/wp-content/uploads/2025/04/2025-Thoracic-Surgery-and-Vascular-Surgery-MRS-Report.pdf ↩ ↩2 ↩3

  8. CT workforce shortage: HRSA projects thoracic surgery among the largest specialty shortfalls (~31% by 2035), with ~900 retirements against ~20% rising demand. STS advocacy page, which prints all three: "HRSA recently projected that cardiothoracic surgery will have the largest projected shortfall of any physician specialty evaluated by 2035," "HRSA expects 900 cardiothoracic surgeons will retire while total demand during the same time period will increase by 20 percent," and "The result will be a projected 31 percent shortfall of surgeons within the specialty." https://www.sts.org/advocacy-issue-physician-workforce ; STS, "Physician Workforce" summary (2023), a one-page advocacy flyer that carries the HRSA largest-shortage line and "Approximately 8 out of 10 cardiothoracic surgeons are hospital employees," https://www.sts.org/sites/default/files/Advocacy/STS-PhysWorkforce-summary-2023.pdf . Corrected 2026-08-17: this footnote also credited the workforce-growth, trainee-count and new-surgeons-per-year figures to these two URLs. Read in full, neither contains them. All three are in 9, the STS blog, which the body cites alongside 8 at every point it uses them, and they have been moved there. ↩ ↩2 ↩3

  9. Luis Mariano Cerda, MD — STS blog, "Why Cardiothoracic Surgery Still Matters" (2025): "dying field" reversal, 100% 2025 fill, ~90% male trainees, case-mix shift (structural heart/TAVR, ECMO, lung-cancer screening). It is also the source of the growth series: "between 2005 and 2021, the number of practicing cardiothoracic surgeons in the United States grew from roughly 4,000 to 5,200," "the number of trainees more than doubled, from 230 in 2008 to 519 in 2023," and "Residency programs are graduating an average of 127 new surgeons annually, a 13 percent increase from a decade ago." It restates the HRSA projection as "a 31 percent shortfall by 2035 relative to demand, with 900 surgeons expected to retire while total procedural demand increases by 20 percent." https://www.sts.org/blog/why-cardiothoracic-surgery-still-matters-sustaining-critical-specialty-and-building-its-future ↩ ↩2 ↩3 ↩4 ↩5 ↩6

  10. Doximity 2025 Physician Compensation Report (2024 data) — thoracic surgery average total comp $689,969, #2 of all specialties (behind neurosurgery $749,140); ~37,000 surveys, full-time ≥40 hrs/wk, multivariate-adjusted; US physician pay +3.7% YoY. https://www.doximity.com/reports/physician-compensation-report/2025 ↩ ↩2 ↩3 ↩4 ↩5

  11. FastRVU's modeled productivity → pay benchmarks — employed median ~$530,000; low-volume ~$450k, high performers ~$680k; median ~8,900 wRVU/yr (25th 7,200 · 75th 11,000 · 90th 13,500); ~$60/wRVU; 2026 CMS conversion factor $33.40. https://fastrvu.com/specialties/cardiothoracic-surgery Corrected 2026-08-17: this footnote and six places in the body labeled these figures "MGMA 2024," which FastRVU prints on a model it also disclaims as not a licensed MGMA table. The label is gone from all seven, including the dashboard row and the compensation image slot, and FastRVU is named where a reader meets each number. No figure changed. The "2024" went with the label, because it was an MGMA vintage the aggregator had borrowed. ↩ ↩2 ↩3 ↩4 ↩5

  12. SalaryDr 2026 (self-report, n=23 — small sample, verify) — median $1.2M, avg ~$1.5M; distribution 10th $500k / 25th $1.0M / median $1.2M / 75th $1.3M / 90th $2.95M; range $500k–$5.17M; ~91% would choose again, satisfaction ~4.1/5; 72 hrs/wk ($404/hr); 57% hospital-employed; median bonus ~$250k (~15% of comp), 74% receive one; early-career→10+ yr +~45%. https://www.salarydr.com/specialty/cardiothoracic-surgery Corrected 2026-08-17: the Wellbeing section quoted the 91% would-choose-again figure as "a 2026 self-report" without naming the host or the n, which this site's compensation standard requires in the visible sentence. Both are now there. A survey of 23 people is not a fact about a field of several thousand, and three other sentences on this page already said so. ↩ ↩2 ↩3 ↩4 ↩5 ↩6 ↩7 ↩8 ↩9

  13. BLS OEWS, "Surgeons, All Other" (SOC 29-1249), May 2025: mean $373,930 ($179.78/hr) on employment of 25,140, with a median of $414,010, a 75th percentile of $511,420 and a 90th of $655,320. A broad bucket covering many surgical fields, so it is floor and context rather than a CT-specific figure. US Bureau of Labor Statistics, Occupational Employment and Wages — May 2025, Table 1 (https://www.bls.gov/news.release/archives/ocwage_05152026.htm). Updated 2026-08-18: this note carried the May 2023 mean of $343,990 and reported the top percentiles as suppressed. The mean has since moved to $371,280 in May 2024 and $373,930 in May 2025, and the May 2025 release publishes the full ladder. The page it cited, https://www.bls.gov/oes/2023/may/oes291249.htm, is still live but holds May 2023 data; the Bureau stopped producing that per-occupation view after the May 2023 release. ↩

  14. Career-stage bands, academic-vs-private structure, call-pay/niche premiums, urban-vs-rural direction, and trainee→attending pay jump. ResidencyAdvisor, "Cardiothoracic Surgery Residency & Physician Salary Guide" (2024 composite of Medscape/Doximity/MGMA — indicative bands, not per-figure attributed). https://residencyadvisor.com/resources/residency-application-guide/cardiothoracic-surgery-residency-physician-salary-guide Corrected 2026-08-17: ResidencyAdvisor is now named in the two body sentences that quote its bands, the career-stage ladder and the academic-vs-private structure. Its own page describes them as a composite of Medscape, Doximity and MGMA with no per-figure attribution, so a reader should know the bands are an aggregator's synthesis before reading them as survey output. The geography and call-pay sentences citing this footnote quote no dollar figure from it. ↩ ↩2 ↩3 ↩4 ↩5 ↩6

It is base-weighted and so runs low against total-compensation surveys, and it is used here for percentile structure rather than for levels. ↩
