What Is Their Training?

Cardiothoracic surgeon training includes:

  • 4 years of pre-medical education at a college or university
  • 4 years of medical school — a medical degree (MD) or doctor of osteopathic medicine (DO) degree
  • 4–5 years of a general surgery residency then 2–3 years of cardiothoracic surgery residency or a 6-year cardiothoracic surgery residency

They also might do a fellowship in a subspecialty such as pediatric or transplant cardiothoracic surgery or cardiac surgery. A “fellow” is a doctor who undergoes more specialty training after completing medical school and a residency.

Good to Know

Cardiothoracic surgeons diagnose and treat problems in all organs of the chest including the lungs, esophagus, and heart. Cardiac surgeons get extra training in a fellowship and focus on problems of the heart.
