[A case of operation for acute postinfarction mitral insufficiency due to papillary muscle rupture]

A 75-year-old man was brought to hospital with complaining of chest pain. He was diagnosed acute myocardial infarction and treated medically using thrombolytic drugs. Without chest pain relieved, cardiac catheterization revealed three coronary vessel disease and severe mitral insufficiency (MR). MR was diagnosed due to papillary muscle rupture by echocardiography. After being transferred to our hospital, the patient developed in shock and underwent emergency operation with IABP inserted. Triple CABGs (to LAD, PD and 4PL) and mitral valve replacement were performed using saphenous vein grafts and a mechanical valve (Carbomedicus 25 M). The patient recovered gradually and discharged one and a half month after operation.
