Key result
Late-onset sustained ventricular tachycardia developed 71 hours after deployment of an Amplatzer-type occluder for perimembranous VSD, which was successfully corrected with antiarrhythmic drugs.
Case Report (n=1)
Sustained ventricular tachycardia can occur as a late-onset complication following Amplatzer-type occluder deployment for perimembranous VSD, but can be successfully managed with antiarrhythmic drugs.
May warrant vigilance for late VT after Amplatzer occluder in perimembranous VSD; case report leaves open incidence and surveillance needs.
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.

Zhou et al. (2012) conducted a case report in Perimembranous ventricular septal defect (PmVSD) (n=1). Amplatzer-type occluder deployment was evaluated on Late-onset sustained ventricular tachycardia. Late-onset sustained ventricular tachycardia developed 71 hours after deployment of an Amplatzer-type occluder for perimembranous VSD, which was successfully corrected with antiarrhythmic drugs.
