Acute Right Coronary artery Occlusion During Cooled-Tip Radiofrequency Ablation of the Cavotricuspid Isthmus

Abstract

Cooled-tip radiofrequencycatheter ablation of the cavotricuspid isthmus, performed after pulmonary vein isolation, resulted in acute occlusion of the posterolateral branch of the right coronary artery in a 49-year-old male with previously known right coronary artery disease. The occlusion was successfully stented. It is conceivable that previously diseased coronary arteries are more prone to be damaged during ablation.
