title: Percutaneous closure of an iatrogenic atrial septal defect.
abstract: The use of the Tandem Heart percutaneous ventricular assist device (Tandem Heart pVAD, Cardiac Assist technologies, Pittsburgh, PA) as a bridge to recovery or to other cardiopulmonary support systems has been rising. One requirement for placement of this device is an intraatrial septostomy which is usually closed during the surgical insertion of more permanent ventricular assist devices. We present a case of a 62-year-old man with a residual acquired atrial septal defect (ASD) from Tandem Heart placement, which could not be closed surgically during insertion of left and right ventricular assist devices. The patient remained intubated and hypoxemic after removal of his right ventricular assist device due to the presence of persistent right to left shunting. With closure of the ASD using an 8-mm Amplatzer septal occluder (ASO; AGA Medical Corp., Golden Valley, MN) the patient stabilized and was successfully extubated.
