The Society of Thoracic Surgeons:
A CARDIOTHORACIC SURGEON IS A MEDICAL DOCTOR WHO SPECIALIZES IN SURGICAL PROCEDURES OF THE HEART, LUNGS, ESOPHAGUS, AND OTHER ORGANS IN THE CHEST. THIS INCLUDES SURGEONS WHO CAN BE CALLED CARDIAC SURGEONS, CARDIOVASCULAR SURGEONS, GENERAL THORACIC SURGEONS, AND CONGENITAL HEART SURGEONS.
Cardiothoracic surgeons will graduate from medical school and go on to complete either a 5-year general surgery residency followed by a 2- or 3-year cardiothoracic surgery residency program, or enter into a 6-year integrated cardiothoracic surgery residency.
Some cardiothoracic surgeons choose to do additional training in a subspecialized area but this training is optional with the exception of congenital heart surgery, which requires completion of a 1-year fellowship.
