[Emergency Mitral Valvoplasty for Papillary Muscle Rupture].

We experienced 2 emergency surgical cases of severe mitral valve regurgitation due to papillary muscle rupture. Case 1:a 69-year-old man presented with respiratory and cardiac failure due to mitral regurgitation. He had no history of myocardial infarction. Mitral valve repair with artificial cords was performed. The papillary muscle of the anterior leaflet was ruptured. The postoperative course was uneventful. Case 2:a 80-year-old man came to our hospital with cardiac arrest. Emergency coronary intervention was performed to the right coronary and intraaortic balloon pumping was inserted. However his condition remained unstable. Severe mitral regurgitation was found by teansesophageal echo cardiography, and he underwent emergency mitral valve repair and single coronary bypass grafting. His cardiac function recovered quickly, but severe brain damage remained.
