Can heart bypass surgery be done more than once in a lifetime?

Yes, heart bypass surgery can be done more than once in a lifetime. However, repeat bypass surgery is generally considered to be a more complex procedure than the initial bypass surgery, and it is associated with a higher risk of complications.

The decision of whether or not to undergo repeat bypass surgery is made on a case-by-case basis, taking into account the patient's individual medical condition and the potential risks and benefits of the surgery. In general, repeat bypass surgery is only recommended for patients who are experiencing significant symptoms of coronary artery disease despite medical therapy and/or percutaneous coronary intervention (PCI).

The success rate of repeat bypass surgery is generally lower than that of initial bypass surgery, and the risk of complications is higher. However, repeat bypass surgery can still be a lifesaving procedure for patients with severe coronary artery disease who have exhausted other treatment options.
