Successful Aortic Valve Repair for Chronic Aortic Regurgitation due to Spontaneous Avulsion of the Aortic Valve Commissure

Abstract

Avulsion of the aortic valve commissure, defined as the detachment of the commissure from the aortic wall, is a rare cause of aortic regurgitation. It is frequently associated with bacterial endocarditis, blunt chest trauma, or ascending aortic dissection and often is manifested as an acute condition. Aortic valve replacement combined with aortic surgery is the most common treatment of such patients. Herein, we report a successful case of aortic valve repair for chronic aortic regurgitation caused by the spontaneous avulsion of the aortic valve commissure.
