Abstract

Left ventricular assist devices are used to provide mechanical circulatory support during end-stage heart failure either as a destination therapy or as a bridge to heart transplantation. Perioperative transesophageal echocardiography is becoming an invaluable tool to investigate device function during implantation and in case of mechanical malfunction. Most malfunctions are due to inflow graft occlusion, or device malfunction, while outflow graft dysfunction is rare. Here, we present a case of severe outflow conduit obstruction by a rare environmental fungus, Myceliophthora thermophila. After replacement of the infected device and intensive antifungal treatment, heart transplantation was performed 2 yr later.
