Safety and Feasibility of Cryothermal Ablation Within the Mid‐ and Distal Coronary Sinus

Abstract

Catheter-based cryoablation can produce lesions in the musculature of the adjacent atrium and ventricle when accessed from the coronary sinus without significant injury to the coronary sinus or adjacent artery. This method has potential application as the ablation method of choice when such lesions are required.
