While typically used for acute support up to FDA\u2010approved 14\u2009days, reports of prolonged utilization remain limited. We present the case of a 69\u2010year\u2010old male who presented with severe biventricular failure and cardiogenic shock who was bridged to heart transplantation (HT) utilizing a single Impella 5.5 for a total of 276\u2009days. His prolonged support course was managed through a multidisciplinary approach addressing recurrent ventricular arrhythmias, renal failure, heparin\u2010induced thrombocytopenia, and device management (suction alarms and purge flow limitations). Following successful HT, the explanted device demonstrated no mechanical injury or thrombus, and pathologic examination revealed no significant device\u2010related structural heart damage. The patient was discharged without major complications and continued to do well at 5\u2010month
