Pulmonary vein isolation is an effective treatment for patients with atrial fibrillation (AF).Although vasospastic angina (VSA) is not a common complication after ablation of AF, we report 3 cases of VSA following ablation of persistent AF. Two of the 3 patients felt chest pain following pulmonary vein isolation, and complex fractionated atrial electrogram ablations were performed. ST elevation in the inferior leads and atrioventricular block occurred because of severe coronary vasospasm. In the third patient, the electrocardiography monitor detected transient ST elevation within an hour after ablation. Treatment of VSA may be required following catheter ablation of AF.
肺静脉隔离术是治疗心房颤动（AF）患者的一种有效方法。虽然血管痉挛性心绞痛（VSA）并非房颤消融术后的常见并发症，但我们报告了3例持续性房颤消融术后发生VSA的病例。3例患者中有2例在肺静脉隔离术后出现胸痛，并进行了碎裂心房电图消融。由于严重的冠状动脉痉挛，下壁导联出现ST段抬高和房室传导阻滞。在第3例患者中，心电图监测在消融后1小时内检测到短暂的ST段抬高。房颤导管消融术后可能需要对VSA进行治疗。
