Veno-arterial mechanical support as bridge to surgery in a patient with severe aortic regurgitation: a case report

Abstract

In this case report, we describe the successful application of veno-arterial extracorporeal membrane oxygenation support in a young patient with severe aortic regurgitation caused by a blocked mechanical valve. In this situation, extracorporeal membrane oxygenation mechanical support was used as a bridge to the prompt replacement of the diseased valve. Aortic regurgitation is commonly recognized as a contraindication to extracorporeal membrane oxygenation support because of the risk of ventricular distension, pulmonary oedema and further organ failure. However, in certain cases and with a rapid decision making, extracorporeal membrane oxygenation can be used as a bridge to treatment and recovery.
