Mechanical Circulatory Support With Impella Percutaneous Ventricular Assist Device as a Bridge to Recovery in Takotsubo Syndrome Complicated by Cardiogenic Shock and Left Ventricular Outflow Tract Obstruction

Abstract

A 71-year-old woman developed stress-related Takotsubo syndrome (TTS) with cardiogenic shock (CS). The left ventricular (LV) ejection fraction was 30%, with apical ballooning and LV outflow tract obstruction (LVOTO) with a peak gradient of 110 mm Hg and severe mitral regurgitation due to systolic
