In this video, Dr. OP. Yadava, Chief Executive Officer & Chief Cardiac Surgeon, National Heart Institute, New Delhi, talks about when should we go or not go in for a bypass surgery. Bypass surgery is based on multiple factors such as patient’s symptoms, the coronary anatomy, the type and degree of the blockage, the financial status whether the patient could afford the surgery and also his psychological state. He also talks about how to manage mild to moderate blockages with the help of medical therapy. And patients who have disease which can be corrected by angioplasty then it is a preferable option over bypass surgery.
