How long does angioplasty last for?

Q: My husband got an angioplasty done seven years back. I want to know for how many years does this last and would he need a bypass surgery after a few years?

A:Angioplasty can last many years and it is difficult to predict as to how long shall it remain open. He shall require bypass surgery only when his vessels reocclude and that you will come to know when he develops symptoms again or by coronary angiography.
