A Cardiothoracic surgeon in the U.S. is a physician (D.O. or M.D.) who first completes a general surgery residency (typically 5â7 years), followed by a cardiothoracic surgery fellowship (typically 2â3 years).
A cardiac surgery residency typically comprises anywhere from 9 to 14 years (or longer) of training to become a fully qualified surgeon. Cardiac surgery training may be combined with thoracic surgery and / or vascular surgery and called cardiovascular (CV) / cardiothoracic (CT) / cardiovascular thoracic (CVT) surgery. cardiac surgery residency typically comprises anywhere from 9 to 14 years (or longer) of training to become a fully qualified surgeon.
