<p>A 79-year-old woman was admitted with a left femoral neck fracture and she immediately developed circulatory shock. Echocardiography showed a markedly enlarged right ventricle (RV) with systolic ballooning of the mid-ventricular wall and preserved contractility of the apex. The left ventricular (LV) motion was normal. Multi-detector-row computed tomography showed severe congestion of the contrast media in the right atrium with no forward flow to RV, but no pulmonary embolism. She was successfully treated with percutaneous veno-arterial extracorporeal membrane oxygenation. This case presented with acute, profound, but reversible RV dysfunction triggered by acute stress in a manner similar to that seen in LV stress cardiomyopathy. </p>
