Overview

High success in this cohort should not yet change practice; leaves open need for randomized confirmation of durability and generalizability.

Key Points

  • This research aims to evaluate the safety, efficacy, and reproducibility of a simplified strategy for achieving pulmonary vein isolation.
  • Included 771 patients undergoing first-time pulmonary vein isolation from January 2022 to May 2025.
  • Performed point-by-point radiofrequency ablation under general anesthesia with a target interlesion distance of 3 mm.
  • Followed patients with Holter monitoring at 3, 6, 12 months, then biannually.
  • At one-year follow-up, 86% of patients were free from all atrial arrhythmia recurrence.
  • Procedural time averaged 100 minutes, with 48.6% cases completed without fluoroscopy.
  • Only 0.4% of patients developed pulmonary vein stenosis, with no cases of atrial-esophageal fistula.
