Article Synopsis
- This study investigates the effectiveness of cryoballoon ablation (CBA) of the left atrial roof using the POLARx catheter compared to the AFA-Pro in patients with persistent atrial fibrillation.
- The results show that POLARx achieved a complete conduction block more effectively and maintained a significantly lower cryoballoon temperature during the procedure compared to AFA-Pro.
- As a result, POLARx eliminates the need for rapid right ventricular pacing, making the procedure simpler and more efficient for achieving the desired outcomes.
Narrow QRS Regular Tachycardia With VA Dissociation: What Is the Mechanism?

Background: Ethanol infusion into the vein of Marshall (EIVOM) has been performed as an adjunctive atrial fibrillation therapy. However, the time course change, quantitative lesion investigation, and effects on epicardial fat pads and fractionated atrial electrograms created by EIVOM have never been investigated.
Objective: This study aimed to perform a quantitative analysis of lesions created by EIVOM.
Background: The anatomical approach for the management of para-Hisian ventricular arrhythmias (VAs) with QRS morphological changes after catheter ablation (CA) has not been well investigated.
Objective: We aimed to evaluate the electrocardiographic and electrophysiological findings and ablation outcomes of para-Hisian VAs with QRS morphological changes after CA.
Methods: Of the 30 patients who underwent CA for para-Hisian VAs at 4 institutions, 10 (33%) had QRS morphological changes after ablation.
