Abstract
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.
