Amiodarone is frequently used to treat arrhythmias in patients supported with left ventricular assist devices. Long term amiodarone use can cause hyperthyroidism ultimately leading to cardiomyopathy and sometimes thyrotoxicosis-induced cardiogenic shock (CS). We describe two cases of thyrotoxicosis-induced CS rescued by successful thyroidectomy under mechanical circulatory support (MCS) – one with a Heartmate III (Abbott Laboratories) and another supported with veno-arterial extracorporeal membrane oxygenation (V-A ECMO). In refractory CS, the initiation of V-A ECMO as a bridge to recovery is critical. In thyrotoxicosis-induced CS that is refractory to medical therapy requiring MCS, thyroidectomy is feasible, and a growing body of evidence suggests that it is safe.
