We present the case of a 70-year old woman who had elective mitral and aortic valve surgery. She underwent surgery without complications for about 4 h until 4 pm. Approx. 3 h after surgery her condition deteriorated. 1500 ml of blood were collected in the chest drainage until 11 pm. An emergency thoracotomy in the patient's bed showed a ventricular rupture. Death occurred around 11:30 pm.At autopsy, the implants of the biological mitral and aortic valves were found to be sewn tightly. There was no vascular injury and no unusual bleedings to the mediastinum. In the left ventricular wall, a rupture of 1 cm and a surrounding fresh myocardial infarction area of 10 cm × 6 cm was noted. Preparation of the coronary arteries showed moderate coronary atherossclerosis without stenosis or clots. The left circumflex coronary artery (LCX) showed a sharp, obviously stenosing kink which had been caused by the mitral valve surgery.Exsanguination due to ventricular rupture following myocardial infarction caused by implant-related “kinking” of a coronary artery, was found to be the cause of death.
