Presentation, history, intervention
A 77-year-old man with a history of ischemic cardiomyopathy and decompensated heart failure, requiring hemodynamic support with a HeartMate II left ventricular assist device, was admitted with melena of several weeks' duration. Hemoglobin level was 8.0 g/dL (normal 14-16 g/dL) and the international normalized ratio was 2.0. He had a remote history of a large anterior wall myocardial infarction requiring subsequent coronary artery bypass grafting. One year before this admission the patient was
Discussion
Mechanical support with an implantable ventricular assist device is routinely used in patients with decompensated cardiac disease in need of temporary circulatory support while awaiting cardiac transplantation. LVADs were initially approved by the Food and Drug Administration for bridging therapy before cardiac transplantation.4 More recently, LVAD use has been shown to improve long-term survival in patients with intractable heart failure who are not candidates for cardiac transplantation.5
