Successful use of extracorporeal cardiopulmonary membrane oxygenation in acute severe aortic regurgitation with cardiovascular collapse

Abstract

We report the case of a 55-year-old man who was transferred from an overseas institution with an initial impression of non-ST-elevation myocardial infarction (NSTEMI). Subsequent investigation found a severe aortic regurgitation (AR) complicated by acute ischemic hepatitis and acute renal injury, and the patient developed cardiopulmonary collapse with pulseless electrical activity perioperatively. Cardiopulmonary resuscitation was commenced immediately, venoarterial extracorporeal membrane oxygenation (ECMO) was immediately set up to bridge for emergency aortic-valve replacement surgery. The patient was subsequently weaned off ECMO and made a complete recovery. We demonstrate the successful use of ECMO for resuscitation in a patient with AR complicated by cardiovascular collapse.
