Percutaneous aortic valve closure for patients with left ventricular assist device-associated aortic insufficiency

Abstract

The development of de novo aortic insufficiency (AI) is a significant complication of long-term LVAD support, which can lead to ineffective support, decreased device durability, end organ malperfusion, and increased mortality. Surgical aortic valve (AV) closure has been the standard treatment for symptomatic patients, but is associated with high mortality and recurrence of AI. Percutaneous AV closure using the Amplatzer cribriform device is a feasible and may be the preferable option to treat LVAD-associated severe AI in high-surgical risk patients. Certain technical issues with this procedure should be taken into consideration to achieve optimal results. © 2015 Wiley Periodicals, Inc.
