What Is Their Training?

Cardiothoracic surgeon training includes:

• 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.
