Late Onset Valve Dislocation of the Edwards Intuity Rapid-Deployment Bioprosthesis

摘要

Over the last decade, aortic valve replacement with rapid-deployment biologic bioprostheses has become a common alternative to the use of mechanical or biologic stented valves for high-risk patients. A 63-year-old patient underwent uncomplicated valve replacement with the Edwards Intuity valve (Edwards Lifesciences, Irvine, CA). Two months postoperatively, the patient had progressive dyspnea. Echocardiography showed a dislocated aortic valve reaching into the left ventricular outflow tract and impairing the anterior mitral valve leaflet. Both valves were replaced by a conventional stented bioprosthesis. This case report describes the first case of valve migration for the Edwards Intuity Elite rapid-deployment aortic valve and discusses possible explanations.
