Case Report

Abstract

The use of a left ventricular assist device has increased and is a primary surgical treatment for heart failure. However, one major complication of left ventricular assist device support is an obstruction in the blood flow pathway. Pump thrombosis and outflow graft occlusion are some of the common causes of such obstructions. Here, we describe a unique case of HeartMate II (Abbott Laboratories) inflow cannula obstruction from a membranous structure without evidence of thrombus. The histology showed evidence of fibrous tissue and heart muscle tissue in the membrane. The patient underwent a successful device exchange with a HeartMate 3 (Abbott Laboratories) and is doing well.
