Scar-related ventricular tachycardia (VT) ablation involves localizing the critical isthmuses by overdrive pacing maneuvers and three-dimensional activation mapping. Implantable prosthetic devices have been known to complicate this by covering sites of potential isthmuses. We herein present a sentinel report of scar-VT ablation with a protected isthmus localized over an endothelialized post-myocardial infarction ventricular septal defect occluder device.

瘢痕相关室性心动过速（VT）消融术通过超速起搏操作和三维激动标测来定位关键峡部。已知植入式假体装置会覆盖潜在峡部部位，从而使这一过程变得复杂。我们在此报告一例具有里程碑意义的病例，该病例为瘢痕性室速消融，其关键峡部位于心肌梗死后室间隔缺损封堵器内皮化装置之上。
