In a 73-year-old man, ventricular septal rupture and tricuspid papillary muscle rupture were complicated with inferior acute myocardial infarction (AMI). Twenty-five days after AMI, radical operation was performed. VSR was found 1.5cm diameter at the inferior septum and directly closed using teflon felt strip. Infarctectomized inferior LV free wall was closed with woven Dacron patch which was cut from Cooley low porosity aortic tube graft and sutured with bovine pericardium facing to LV cavity. A part of anterior tricuspid papillary muscle was found to be ruptured. Tricuspid valve replacement was performed with Carpentier-Edwards valve. One and half year postoperatively, the patient has been doing well without heart failure. To our knowledge, this is the first case of VSR complicated with tricuspid papillary muscle rupture following AMI.
