Catheter Closure of Congenital/Acquired Muscular VSDs and Perimembranous VSDs Using the Amplatzer Devices

Abstract

Over the past 10 years a variety of occluding devices has been used for transcatheter closure of ventricular septal defects (VSDs), but none has gained wide acceptance. This article presents the experience of transcatheter closure of muscular and perimembranous VSDs in 22 and 13 patients, respectively, with the new Amplatzer VSD occluders. Overall total occlusion was achieved in 95% and 92.3% of patients with muscular and perimembranous VSDs, respectively. The main complication was embolization of the device in 1/13 (7.6%) patients with perimembranous VSDs. Transcatheter closure of VSDs using the Amplatzer VSD occluders appears to be a safe and effective alternative to the standard surgical treatment.
