Successful extended use of Impella 5.5 as a bridge to heart transplantation

We present the case of a 60-year-old gentleman who was admitted with acute-on-chronic cardiogenic shock and was supported with axillary Impella 5.5® for 123 days prior to heart transplantation. Total length of temporary mechanical circulatory support (MCS) was 132 days, which included 9 days with an intra-aortic balloon pump prior to Impella. During support, the patient remained extubated, participated in regular ambulation and rehabilitation with physical therapy and had continuous monitoring of device positioning. He did not experience any vascular or septic events while on temporary MCS and had improved hemodynamics and renal function after Impella initiation. Post-transplantation course was uncomplicated, and he is doing well without evidence for allograft dysfunction over 581 days post-transplantation. To our knowledge, this is the longest Impella 5.5®-supported patient during the new United Network for Organ Sharing Heart Allocation era who was successfully bridged to heart transplantation with over 1-year follow-up.
