Cardiothoracic surgery is a broad term encompassing almost all surgery that takes place in the chest, and encompasses cardiac, thoracic, and congenital heart surgery. These areas of surgery on the chest are usually divided into three categories with surgeons specializing in one area, but the term cardiothoracic surgery groups them all together. The distinctions of each area of expertise are nevertheless important to understand.

Theoretically, the term cardiothoracic surgery describes surgeries in the chest or thorax. Yften, lines are drawn between those surgeries that most specifically treat the lungs and those surgeries that treat the heart and great vessels, even if surgeons have roughly equivalent training. A further separation is between cardiovascular and lung surgeons and those doctors who specialize in pediatric cardiothoracic surgery. The pediatric doctor is usually most trained of the three areas, since he or she has completed additional study after becoming board certified as a cardiovascular or thoracic surgeon.


All of these doctors have an average of seven to nine years training after medical school, but pediatric surgeons may add two more years of fellowship training to this, and anyone specializing in transplant technology may spend more time studying. What is important to understand for the layperson is that surgeons who specialize in a particular area treat complex diseases of that area best. Someone specializing in pediatric cardiothoracic surgery is most qualified to repair defects in children’s hearts and a person who has specialized in lung transplant would be the best doctor to see if this is required. Most general cardiac surgeons are logical choices for surgical treatments of adult or acquired heart disease.

There are a number of surgical interventions that may be offered by doctors specializing in cardiothoracic surgery. When grouped all together, these offer a plethora of ways to approach heart or lungs from a surgical perspective. Some of the things specialists in cardiothoracic surgery might do include the following:

These are just a sample of some of the interventions cardiothoracic surgery provides, and increasingly, surgeons share repairs with cardiac interventionists who can do things like widen arteries or place stents in catheterization labs. Interventionists are not surgeons but they’ve discovered non-surgical methods for addressing heart problems that were once only cured through surgery.
