Mechanical circulatory support devices in adults with congenital heart disease

Abstract

Purpose of review Mechanical circulatory support is used frequently as a method of stabilizing patients with end stage heart failure who are unable to safely await allograft availability. While this technology has been fundamentally important in supporting patients with normal cardiac anatomy, it is still used infrequently in adult patients with congenital heart disease and end-stage heart failure. Here, we review the data on mechanical circulatory support technology in this small but growing population of patients with chronic heart disease prone to the development of circulatory failure. Recent findings Mechanical circulatory support (MCS) has been increasingly employed in adults with congenital heart disease (ACHD) as a bridge to transplant. The new United Network for Organ Sharing listing system favoring temporary MCS use with a higher listing status offers another tool to stabilize ACHD patients and potentially shorten wait times. Both temporary and Durable MCS could help improve transplant candidacy and posttransplant outcomes in select groups of ACHD patients. Summary Durable and temporary MCS have the potential to significantly improve access to transplant and overall transplant outcomes in ACHD patients.
