The Match That Quietly Got Twice As Hard

If you trained a decade ago, or if you are advising someone who is applying right now based on how things used to work, the numbers I want to show you today will genuinely surprise you.

Traditional cardiothoracic fellowship match rate

2011 match · 97.5%
Nearly every applicant matched
2021 match · 59.1%
Match rate down by nearly 40 points
2025 match · 58.8%
Holding steady at the new, far more competitive baseline

That is not a gradual drift. That is a field that fundamentally changed its risk profile within a single career. If you applied in 2011, you were choosing a specialty. If you are applying today, you are competing for one of fewer than 100 traditional fellowship positions nationwide, 97 in the 2025 match, full stop, regardless of how the rest of your application looks.

The main cause is not fewer positions. It is roughly twice as many applicants chasing about the same number of spots.

This is confirmed by more than the raw match rate. A peer reviewed competitiveness analysis comparing 2015 to 2019 against 2020 to 2024 found that thoracic surgery became significantly more competitive over that window, using a standardized index designed for exactly this comparison, while two others, pediatric surgery and complex general surgical oncology, actually became less competitive over the same period. This is not a general trend across all of surgery. It is specific to this field.

Interest in cardiothoracic surgery did not fade and come back. It never left. What changed is how many people now realize that, and are applying accordingly.

If you are applying, or advising someone who is

  1. Understand which pathway you are actually applying through. The traditional route through general surgery residency and the integrated six year pathway have different timelines, different competitiveness profiles, and different application strategies. Confusing the two costs applicants real opportunities every cycle.
  2. Treat research output as a genuine differentiator, not a checkbox. In one survey of applicants to integrated programs, 92 percent had done research in medical school, most of them within cardiothoracic surgery, and 76 percent had published it. In a field where the match rate has fallen by nearly 40 points, a thin, generic research line is easy to screen past.

If you are building the research portfolio that this match increasingly requires, that groundwork is worth starting well before application season, not during it. AskDimitri can help you think through a research plan that actually strengthens an application in a field this competitive.

A specialty does not become twice as competitive by accident, and it does not stay that way by accident either. If you want in, the honest starting point is knowing exactly what field you are actually walking into.

Editor's note: in October 2026 the figures in this letter were checked against the sources listed below, and the text was corrected where the letter as sent differed from them. Two paragraphs and one step about the interview timeline were removed: they described the fellowship's interview offers as decentralized and rolling, and the program directors' association now sets a universal interview offer date.

Until next week,

Dimitri
