title: Late infective endocarditis of an atrial septal occluder device presenting as a cystic mass.
abstract: We report an atypical echocardiographic presentation of a vegetation in a patient with late infective endocarditis of an atrial septal defect (ASD) occluder device. Transesophageal echocardiography demonstrated a penduculated mass attached to the left atrial side of the occluder device. This mass presented as an oscillating echo free area surrounded by a membrane attached to the device by a thin stalk. At time of surgical excision, the lesion did not present as a spherical cyst. It was assumed that the content of the echo free mass had already emptied into the left atrium. Histopathology diagnosed the mass as a vegetation. The contribution of contrast echocardiography to the evaluation of intracardiac masses is briefly discussed.
