Being a Cardiac Surgeon is basically focused on people's heart or great vessels. The cardiac surgeon is in charge of doing heart transplants or treating disease that affect the heart. A surgeon must be prepared for the worse. When it comes to a transplant it cna take up many hours. It an last up to twenty-four hours depending on how well the transplant goes. I believe that this career choice would be intresting, if not ther is always being a neurologist.
