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.

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

Chest tube thoracostomy is a standard procedure in every intensive care unit. Although it is regarded as a safe procedure in experienced hands, rare complications do occur. This report describes iatrogenic perforation of the left ventricle after placement of an intercostal catheter and the successful surgical management of this injury. Various operative situations that may arise in relation to iatrogenic perforation of the left ventricle are also discussed, as well as steps to manage this potentially life-threatening complication.
