Complete AV Block Induced by Right Coronary Artery Spasm Following Radiofrequency Ablation for Atrial Fibrillation

J Atr Fibrillation. 2019 Oct 31;12(3):2257. doi: 10.4022/jafib.2257. eCollection 2019 Oct-Nov.


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.
