Abstract

Cyoablation is a ablation technique underutilized except in parahissian pathways and atrial fibrillation ablation. Ablation inside venous coronary sinus remains a dreaded incursion, and cryoablation is rarely used. We present the case of a 43 YO female who had a recurrent wolff parkinson white syndrome due to an epicardial pathway inside the coronary sinus successfully treated with a large bore(8mm) cryocatheter. We also review literature and describe the advantages and similar reports of use of cryo in low flow recesses inside the heart.
