[A case report of left ventricular-right atrial communication due to infective endocarditis].

Left ventricular-right atrial communication is a rare lesion and its etiology is almost exclusively congenital. A case of a 48-year-old woman with left ventricular right atrial communication due to infective endocarditis was presented. The communication was located at the atrioventricular portion of the membranous septum, i.e., supravalvular type, and was closed directly with mattress suture. Aortic valve replacement with 21 mm St. Jude Medical prosthesis was performed simultaneously. The postoperative course was uneventful. This complicated lesion should be surgically managed as soon as the diagnosis is confirmed.
