Complete thrombosis of a bioprosthetic mitral valve and left atrium in a patient on venoarterial extracorporeal membrane oxygenation with favorable outcome

Abstract

Abstract Intra-cardiac thrombosis is a potentially devastating complication of extracorporeal membrane oxygenation (ECMO) mechanical circulatory support. We present here a patient who suffered complete thrombosis of a fresh mitral prosthesis and left atrium in the setting of ECMO with aortic insufficiency who was treated with repeat valve replacement and thrombectomy. To our knowledge, she is the only patient in the reported to have survived this complication.
