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.
经导管室间隔缺损（VSD）封堵术已在全球范围内广泛应用。尽管成功率高，手术死亡率低，但术中及术后心律失常仍时有发生。然而，封堵器植入后发生持续性室性心动过速尚未见报道。本研究报道了 1 例罕见的迟发性持续性室性心动过速病例，该病例发生在 3 岁零 5 个月的男孩中，其因膜周部 VSD（PmVSD）采用 Amplatzer 型封堵器治疗 71 小时后出现持续性室性心动过速。给予利多卡因、胺碘酮和地塞米松治疗后，持续性室性心动过速得到纠正。在最近的 6 个月随访中，未观察到室性心动过速再次发作。总之，本病例提示 Amplatzer 型封堵器治疗 PmVSD 后可能发生持续性室性心动过速，可通过抗心律失常药物纠正。
