Background : In pulmonary vein isolation（PVI）using a three-dimensional mapping system, respiratory stability and suppression of patient movement are crucial for procedural success. Objective : This study aimed to compare the procedural outcomes of pulmonary vein isolation（PVI）performed under deep sedation（DS）versus general anesthesia（GA）. Methods : We retrospectively analyzed patients who underwent PVI between December 2022 and December 2024 （deep sedation group［DS group］, n＝52 ; general anesthesia group［GA group）, n＝70）. The primary endpoint was the time required for PVI. Results : The percentage of patients with persistent atrial fibrillation was higher in the GA group（21.4％）than in the DS group（13.5％）, and long-standing persistent atrial fibrillation was also more frequent（12.9％ vs. 7.7％）, although these differences were not statistically significant（p＝0.28）. Left atrial volume was significantly greater in the GA group（101.5±35.1mL）than in the DS group（78.9±33.1mL, p＜0.05）. The time required for PVI was significantly less in the GA group（35±20.6 minutes）than in the DS group（55.3±29.9 minutes, p＜0.05）. Conclusion : General anesthesia contributed to respiratory stability and suppression of body movement, resulting in a significant reduction in PVI time. These findings suggest that GA may be a useful anesthetic strategy to improve procedural efficiency during PVI.
