Cardiogenic shock is a devastating complication of acute myocardial infarction (MI) with an in-hospital mortality between 40–76%.1,2 Cardiogenic shock from right ventricular infarction is uncommon, though it has a mortality rate equal to that of left ventricular shock.3,4 The TandemHeart (Cardiac Assist, Inc., Pittsburgh, Pennsylvania) is a peripheral ventricular assist device (PVAD) that can be inserted percutaneously to provide short-term mechanical support, primarily during high-risk percutaneous intervention or cardiogenic shock secondary to left ventricular dysfunction.5–11 We report the case of a patient with cardiogenic shock secondary to right ventricular dysfunction bridged to recovery with the TandemHeart as a right ventricular assist device (RVAD).
