Key result
Cooled-tip radiofrequency catheter ablation of the cavotricuspid isthmus resulted in acute occlusion of the right coronary artery in a patient with prior coronary disease.
Case Report (n=1)
Cooled-tip radiofrequency ablation of the cavotricuspid isthmus can cause acute coronary occlusion, particularly in patients with pre-existing coronary artery disease.
Alerts to RCA occlusion risk with cooled-tip CTI ablation in prior CAD; case report leaves open true incidence and mechanisms.
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.

Castellanos et al. (2013) conducted a case report in Right coronary artery disease (n=1). Cooled-tip radiofrequency catheter ablation was evaluated on Acute coronary artery occlusion. Cooled-tip radiofrequency catheter ablation of the cavotricuspid isthmus resulted in acute occlusion of the right coronary artery in a patient with prior coronary disease.
