The formation of early activation regions was demonstrated in the area of the pulmonary vein orifice in hypertensive rats. The appearance of early activation zones on the dorsal side of the left atrium near the pulmonary veins simultaneously with the sinoatrial node in rats with arterial hypertension indicates the possibility of ectopic foci formation in the area of pulmonary vein sleeves.

Localization and Spread of Challenging Conduction Gaps of Pulmonary Veins for Atrial Fibrillation Cryoablation.
Pacing Clin Electrophysiol

Department of Cardiology, International University of Health and Welfare Hospital, Tochigi, Japan.
Background: Cryoballoon ablation has been widely performed in patients with paroxysmal atrial fibrillation (AF). In some challenging pulmonary veins (PVs), the procedure requires additional touch-up applications against the residual conduction gaps. It implies that there could exist difficult sites to cover with standard cryoballoon applications (CBAs), resulting in resistant conduction gaps (RCGs).

Background: Endovascular radiofrequency ablation (RFA) and Endovascular Laser Ablation (EVLA) are minimally invasive methods to safely treat symptomatic varicose veins in pediatric patients. This research aimed to review the management of pediatric patients with venous insufficiency, evaluate the outcome, and determine the efficacy, convenience, and safety of ablation procedures in an outpatient setting.
Methods: A retrospective chart review of all patients seen at six locations from 2013 to 2024 was completed.

Background: The vertical vein (VV) ligation during the total anomalous pulmonary venous return (TAPVR) correction is still controversial. Our study aimed to define the potential risk factors for VV persistence and their percutaneous occlusion.
Methods: The retrospective cohort study included 40 patients (26 males) with TAPVR treated at the tertiary referral center from 2005 to 2024.

Background: Recent studies on bronchiectasis have revealed significant structural abnormalities and pathophysiological changes. However, there is limited research focused on pulmonary venous variability and congenital variation. Through our surgical observations, we noted that coarctation of pulmonary veins and atrophied lung volume are relatively common in bronchiectasis patients.
