Aims Controversial results have been published regarding the influence of pulmonary vein
(PV) anatomical variations on outcomes after pulmonary vein isolation (PVI). However, no …

Background Pulmonary vein (PV) stenosis is an important potential complication of PV
isolation using thermal modalities such as radiofrequency ablation (RFA). Pulsed field …

Background Circumferential pulmonary vein (PV) isolation is the cornerstone of catheter
ablation for atrial fibrillation (AF); however, PV reconnection remains problematic. Objective …

Background—Pulmonary vein stenosis (PVST) is a well-known complication of pulmonary
vein isolation (PVI). Specific anatomically designed ablation catheters for antral PVI have not …

Introduction: Delineation of pulmonary vein (PV) anatomy is an integral part of the PV
isolation procedure. The aims of the present study were to (1) describe the technique of …

Background: The morphology of the pulmonary veins (PVs) before and after segmental
isolation of the PVs has not been sufficiently characterized. Methods and Results: Multi‐slice …

Background Novel atrial fibrillation (AF) ablation tools have been designed to facilitate
“single-shot” pulmonary vein (PV) isolation using multi-electrode or balloon-based catheters …

Aims Circumferential pulmonary vein isolation (PVI) is the current standard of interventional
atrial fibrillation (Afib) therapy. However, recurrence rate of Afib varies considerably after …

Aims To investigate the impact of variant pulmonary vein (PV) anatomy and the use of three-
dimensional image integration (3D-II) on long-term efficacy of catheter ablation for atrial …

BACKGROUND: Both segmental ostial and circumferential extraostial pulmonary vein (PV)
isolation have been proven effective in the treatment of atrial fibrillation (AF). However, the …
