How long on average does it take to do a heart bypass surgery?

About 4 hours: Well it depends on exactly what type of surgery. Also it depends on whether there are any complicating problems that might occur during the surgery. It also depends on how fast the surgeon is. The result is more important than how long it takes, so if it takes longer, the patient may do fine. I sometimes ask how long does it take you to drive home or bake a cake. It might vary from day to day.

2-4 hours: It depends : first operation how many blockages which grafts(?Artery or vein) experience of surgeon and team other risk factors plavix or other causes of bleeding heart function obesity combined surgery.
