Right coronary cusp ablation for idiopathic VT linked to severe RCA stenosis in 1 case.
Case Report (n=1)
Radiofrequency ablation at the right coronary cusp for ventricular arrhythmias carries a risk of severe right coronary artery ostial stenosis.
May warrant caution with right coronary cusp ablation; leaves open need for systematic safety data.
The aortic cusp has been recognized as a target of radiofrequency (RF) ablation in patients with ventricular arrhythmias.1,2 In some patients, ventricular arrhythmias have been mapped well into the ostial coronary arteries rather than the coronary cusps.3 Coronary artery stenosis is one of the most serious complications of RF ablation.4–6 This is the first case report describing severe right coronary artery stenosis after RF ablation at the right coronary cusp (RCC).

Kusa et al. (2015) conducted a case report in Idiopathic ventricular tachycardia (n=1). Radiofrequency (RF) ablation at the right coronary cusp was evaluated on Severe right coronary artery stenosis. Radiofrequency ablation at the right coronary cusp for idiopathic ventricular tachycardia resulted in severe right coronary artery ostial stenosis in 1 reported case.
