ABSTRACT
A 73-year-old woman with severe aortic stenosis was accepted for transcatheter aortic valve implantation. There was minimal paravalvular leakage after the implantation, and the patient was stable. Twelve minutes after the implantation, the arterial pressure suddenly dropped. Transesophageal echocardiography showed severe left ventricular dysfunction. Cardiopulmonary resuscitation was started, and initially was successful with a systolic blood pressure of 90 mm Hg. However, despite initiation of extracorporeal circulation support, the patient deteriorated, pulmonary edema developed, and she died. Autopsy revealed an inverted aortic valve. The reasons why the patient had cardiac arrest and an inverted transfemoral aortic valve remain unclear.
