How long does heart bypass surgery last?

Depends on YOU.: First, do you have a strong family history? If so, then you need to do all those "lifestyle" things like eat right, exercise, control your cholesterol, etc., and of course have regular doctor visits and do what your doctor tells you! second, do you do anything now that might contribute to recurrent heart disease, like smoke, hold in stress, etc? Stop! these things will maximize the durability!

Do you mean bypass: The goal of coronary bypass is to revascularize the coronary arteries. The internal mammary to LAD bypass has about 97%patency at 15 years. Vein grafts to other territories, 70-75% are patent 10 yrs down. That is not the case on the majority of 2.5mm dia stents.

It varies.: The average cardiac surgeries take about four hours but the actual time on the heart lung machine (bypass time) is about two hours. These time vary depending on the complexity of the procedure being performed.
