The use of occluder devices is gaining increasing popularity for the closure of secundum atrial septal defects (ASD).1Berger F. Vogel M. Alexi-Meskishvili V. Lange P.

We report 2 cases of attempted percutaneous transcatheter ASD closure complicated by embolization necessitating emergency surgical intervention. An asymptomatic 24-year-old woman with an ASD underwent transesophageal echocardiography, which showed a 17- to 19-mm-diameter ASD, and transvenous closure was attempted. A 43-mm Starflex device (NMT Medical, Inc., Boston, Mass) was implanted and seemed in good position. During extubation, the patient experienced an episode of ventricular tachycardia. Repeat transesophageal echocardiography showed translocation of the device and embolization into the right pulmonary artery. Transcatheter retrieval was unsuccessful (Figure 1). At emergency operation, the device was identified and retrieved through the right pulmonary artery through a transverse main pulmonary arteriotomy. The ASD was closed with direct sutures through a right atriotomy. The patient recovered without complications and remains well 6 years later. An asymptomatic 11-year-old boy was found to have a large (2.5 × 2 cm) ASD on transthoracic echocardiography. Transesophageal echocardiography was not performed. Transcatheter closure was attempted, and a 40-mm Amplatzer device (AGA Medical Corp., Golden Valley, Minn) was implanted. After the device was released, it slipped entirely into the left atrium, protruding into the mitral orifice. Retrieval efforts fraught with the risk of mitral disruption or occlusion were unsuccessful. At emergency operation, the ASD was found with no shelf at the inferior margin. The device, covered with recent red thrombus, had embolized entirely into the left atrium, lying on the anterior mitral valve leaflet protruding into its orifice and orientated toward the left atrial appendage (Figure 2). Through the ASD, the device was retrieved without injury to the mitral valve, and the defect was closed with autologous pericardium. The patient had an uneventful recovery and was discharged a week later. He remains well at 1-year follow-up. Transcatheter occlusion techniques have become an increasingly used alternative to surgical closure of the ASD, and various devices are available for this.1Berger F. Vogel M. Alexi-Meskishvili V.

If embolization (for which transcatheter retrieval is unsuccessful) occurs, urgent surgical therapy is necessary.2Chessa M. Carminatti M. Butera G. Binni R.M. Drago M.

Once the device is detached from its cable, it becomes difficult to retrieve, and depending on its location, it might even become lethal. Although transcatheter devices represent useful alternatives to surgical closure in selected cases, they can be associated with failures and, most importantly, with life-threatening complications. Thus proper selection of patient and device is mandatory. Close monitoring and facilities for emergency surgical intervention should be available for all patients.
