Abstract

Transcatheter closure of ventricular septal defect (VSD) has been widely used worldwide. Despite high success rate and minimal operative mortality, arrhythmia during and post-operation has been frequently observed. However, sustained ventricular tachycardia following deployment of occluder has not been reported. In this present case, we present one rare case of late-onset sustained ventricular tachycardia, which developed 71 hr after deployment of an Amplatzer-type occluder for perimembranous VSD (PmVSD) in a 3-year and 5-month-old boy. The sustained ventricular tachycardia was successfully corrected with the administration of lidocaine, amiodarone, and dexamethasone. The reoccurrence of ventricular tachycardia was not observed in the most recent follow-up at 6 month. In summary, the current case indicated that sustained ventricular tachycardia could occur following deployment of Amplatzer-type occluder for PmVSD, which could be corrected with antiarrhythmic drugs. © 2012 Wiley Periodicals, Inc.
