Hi Rahul

A Cardiac surgeon or Cardiothoracic surgeon is someone who actually does surgery on the heart and the blood vessels. This means they open the chest of the patient, often place the patient on a heart-lung machine and perform complex surgery to repair a problem.

Cardiovascular surgeon is same as cardiothoracic surgery but sometimes it may be performed without a cut in the chest divider, for example, angioplasty, stent situation and others. That is reliant upon expertise and experience of the specialist, offices and gear accessibility, different Variables.
