Coronary artery spasm during catheter ablation for arrhythmias is a rare but previously reported complication. Timing of presentation, manifestations of vasospasm, and purported mechanisms vary somewhat in the prior literature. We present a case of chest pain, inferior lead ST elevation, and complete AV block with angiographically confirmed right coronary artery (RCA) vasospasm that occurred immediately after catheter ablation for atrial fibrillation.
心律失常导管消融术中冠状动脉痉挛是一种罕见但此前已有报道的并发症。既往文献中,发作时间、血管痉挛的表现及推测机制略有不同。我们报告一例在房颤导管消融术后即刻发生胸痛、下壁导联ST段抬高及完全性房室传导阻滞,血管造影证实为右冠状动脉(RCA)痉挛的病例。
