Centrifugal continuous-flow left ventricular assist device in patients with hypertrophic cardiomyopathy: a case series

ASAIO J. 2013 Mar-Apr;59(2):183-7. doi: 10.1097/MAT.0b013e318286018d.

Abstract

Left ventricular assist device (LVAD) therapy has been used primarily in patients with end-stage dilated cardiomyopathy (DCM), and patients with hypertrophic cardiomyopathy (HCM) are generally excluded. We compared outcomes in 3 HCM patients with 36 DCM patients. While HCM patients had smaller left ventricular end-diastolic dimensions, average pump flows for the two groups were similar. All patients had marked improvement in mean pulmonary arterial pressures and cardiac index at 5 months. This analysis shows that patients with end-stage heart failure resulting from HCM do benefit from centrifugal cfLVAD therapy in the short to medium term.
