The importance of catheter stability evaluated by Visitag(TM) during pulmonary vein isolation.

Background The recurrence rates of atrial fibrillation (Af) after ablation are still high, and repeat procedures are required in these patients. The main reason for Af recurrence is the recovery of the conduction between the pulmonary veins and left atrium. The importance of catheter stability during the pulmonary vein isolation (PVI) is not well studied.
