Impact of the United Network for Organ Sharing allocation criteria changes on temporary mechanical circulatory support use as a bridge to transplant

Figure 1 Central Illustration: Changes in temporary mechanical circulatory support and durable left ventricular assist devices use as a percentage of total mechanical circulatory support use at time of transplant listing in the 5 years before allocation criteria change (Pre) and 5 years after allocation criteria change (Post). Data for temporary mechanical circulatory support and left ventricular assist devices use is derived from the United Network for Organ Sharing/Scientific Registry of Transplant Recipients 5-year monitoring report. IABPs: Intra-aortic balloon pumps; VA-ECMO: Veno-arterial extracorporeal membrane oxygenation; MCS: Mechanical circulatory support; LVAD: Left ventricular assist devices; VAD: Ventricular assist devices; BiVAD: Bi-ventricular assist device.
