Abstract:
We report here on a surgical case of acquired left ventricular right atrial communication (LV-RA communication) and aortic regurgitation (AR) caused by infective endocarditis (IE). We successfully treated the patient with composite patches made from polytetrafluoroethylene (PTFE) and autologous pericardium. In general, LV-RA communication is a rare congenital cardiac anomaly (Gerbode-type shunt). However, acquired LV-RA communications secondary to IE are occasionally reported.When repairing an acquired condition due to IE, particular care should be taken to avoid recurrence, persistent infection and iatrogenic atrioventricular block.
