Bypass surgery can be performed multiple number of times. In this video, Dr. O P. Yadava, Chief Cardiac Surgeon, National Heart Institute will talk about how many times we can undergo bypass surgery. Second time bypass has become a very standard procedure nowadays. As many of the patients are operated in late 60’s and 70’s so the need for a second bypass surgery arises. There is no specific limit of times that a person can undergo bypass surgery. But with each number of surgery, the risk also goes on increasing.
