Mitral insufficiency ring is typically secured to the annulus, or opening of the mitral valve, to provide additional structural support. In some cases, the "double orifice" (or 'Alfieri') technique for mitral valve repair, the opening of the mitral valve is sewn closed in the middle, leaving the two ends still able to open. This ensures that the mitral valve closes when the left ventricle pumps blood, yet allows the mitral valve to open at the two ends to fill the left ventricle with blood before it pumps. In general, mitral valve surgery requires "open-heart" surgery in which the heart is arrested and
Mitral valve replacement from January 1990 to June 1996 is atrial fibrillation. This occurred in 32% of patients. A common pulmonary complication is congestion necessitating prolonged use of oxygen. Other patients required prolonged ventilation of longer than 24 hours for conditions like pulmonary edema, ARDS, and pulmonary thromboemboli Nine patients had renal failure with six of them dying within 30 days after their operation. Five patients had permanent strokes, and nine patients were readmitted to the hospital within 30 days of their discharge. Many mitral valves can be repaired instead of replaced, especially for minimally damaged valves. Advantages to valve repair instead of
