title: Torn atrial septum during transcatheter closure of atrial septal defect visualized by real-time three-dimensional transesophageal echocardiography.
abstract: Transcatheter closure of atrial septal defects (ASDs) has become an accepted and reliable procedure. Although various complications have been recognized, tear of the atrial septal rim is a rare complication. We report a case of atrial septal rim tear that was diagnosed during the procedure by real-time three-dimensional transesophageal echocardiography (TEE). The device was successfully implanted 3 months after the initial intervention. RT3D TEE is more useful for displaying the entire shape of the defect and its spatial relationship (RT3D) with its neighboring structures compared with conventional two-dimensional echocardiography. By using both two-dimensional and RT3D TEE images, especially in cases with complicated ASD morphology, both the echocardiologist and interventionalist gain valuable information on the morphology of the ASD before and during the procedure.
