Corevalve prosthesis causes anterior mitral leaflet perforation resulting in severe mitral regurgitation and subsequent endocarditis

摘要

An 84-year-old patient presented at our outpatient clinic with recurrent dyspnoea (NYHA class III) and fever. Medical history included transcatheter aortic valve replacement (TAVR) using a 31 mm Corevalve prosthesis 6 months ago. Trans-thoracic echocardi-ography revealed moderate aortic regurgitation and also perforation of the anterior mitral leaflet (AML) causing severe mitral regurgitation (MR; Panels A1 and A2). Thus, the patient was scheduled for open heart surgery.
