There are always risks associated with general anesthesia and cardiopulmonary bypass. Risks specifically associated with mitral valve repair include embolism, bleeding, or operative valvular endocarditis. When valve repair does not produce adequate...
results, then increased operative time is required to replace the mitral valve. If the patient's mitral valve is replaced with a mechanical valve, the patient must take an anticoagulation drug, such as Coumadin, for the rest of his/her life. An inadequately repaired valve, if left untreated, results in continued myocardial dysfunction resulting in pulmonary edema, congestive heart failure, and systemic thromboemboli generation.

This video includes echocardiogram information from a patient showing severe mitral valve prolapse and actual footage during repair of a mitral valve. This view is from inside the heart that has had all of the blood removed and diverted (not shown).
During a mitral valve repair, the patient's chest is opened along the sternum (A). The heart is connected to a heart-lung machine, and an incision is made into the right atrium, or upper chamber of the heart (B), exposing the mitral valve (C). A section of the valve is removed, and the area is repaired with sutures (D and E). A flexible fabric ring may be stitched to the outside of the valve to strengthen it, in a procedure called an annuloplasty (F). (Illustration by GGS Inc.)

Other Information
Mitral valve repair is a cardiac surgery procedure performed by cardiac surgeons to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. The mitral valve is the "inflow valve" for the left side of the heart. Blood flows from the lungs, where it picks up oxygen, through the pulmonary veins, to the left atrium of the heart. After the left atrium fills with blood, the mitral valve allows blood to flow from the left atrium into the heart's main pumping chamber called the left ventricle. It then closes to keep blood from leaking back into the left atrium or lungs when the ventricle contracts (squeezes) to push blood out to the body. It has two flaps, or leaflets.

Heart surgery is quite a big event and people are keen to know about their particular surgeon.
