Trans-catheter closure of peri-membranous ventricular septal defects (VSDs) using Amplatzer-Type devices, has been widely reported in the past decade. We hereby report a rare complication of frequent premature ventricular contractions (PVCs) and paroxysmal ventricular tachycardia (PVT) sustained 48 days after the closure of VSD.More importantly, the arrhythmias were successfully treated with radiofrequency catheter ablation (RFCA) after medical therapy failed to restore and maintain sinus rhythm.
We reported an 8-year-old boy with frequent PVCs and PVT sustained 48 days after the closure of VSD. The boy has no palpitation, chest distress and other uncomfortable symptoms.
This patient was diagnosed as frequent PVCs and PVT by Holter monitoring for 24 hours.
RFCA was administered.
The patient was discharged 48 hours with no complication and remained asymptomatic 12 months after the ablation.
Radiofrequency ablation helps treat PVCs and PVT in children and has a higher efficacy in restoring and maintaining sinus rhythm.
在过去十年中，使用Amplatzer型装置经导管闭合膜周部室间隔缺损（VSD）已有广泛报道。我们在此报告1例VSD封堵术后48天持续存在频发室性早搏（PVC）和阵发性室性心动过速（PVT）的罕见并发症。更重要的是，在药物治疗未能恢复并维持窦性心律后，心律失常通过射频导管消融（RFCA）成功治愈。
我们报告1例8岁男孩，VSD封堵术后48天持续存在频发PVC和PVT。该男孩无心悸、胸闷等不适症状。
通过24小时动态心电图监测，该患者被诊断为频发PVC和PVT。
实施RFCA。
患者术后48小时出院，无并发症，消融术后12个月无症状。
射频消融有助于治疗儿童PVC和PVT，在恢复并维持窦性心律方面疗效较高。
