Could a third open heart surgery be safe?

Yes: Well, it is technically more difficult for a heart surgeon if the patient has had previous surgery, but it still should be safe and, of course, if the surgery is indicated, that is not a reason not to do it. In deciding about whether to operate on a patient, we compare the risk with the potential benefit.

Risky: Risks get higher every time. Potential damage to heart structures , damaging grafts, bleeding, infection are all higher with redo operation.
