Successful Transcatheter Closure of an Aorto-Left Atrial Fistula

Abstract

Aorto-left atrial fistula is a rare entity in which the integrity of the aortic root bordering the left atrium is disrupted. The clinical presentation is highly variable, depending predominantly on the size of the fistula and the pressure difference between the aorta and the left atrium. Surgical repair was the standard treatment. Recently, however, there have been reports of successful transcatheter closure. We report a 32-year-old male with Shone's syndrome who had multiple prior surgical procedures including aortic and mitral valve replacements. He presented with an aorto-left atrial fistula that was successfully closed percutaneously using an Amplatzer atrial septal defect device.
