Redo Ablation Following LSI Algorithm-Guided High-Power Short-Duration vs LSI Algorithm-Guided Conventional Radiofrequency for Atrial Fibrillation
Listen to this summary
The authors aimed to compare the outcomes of redo procedures following pulmonary vein isolation (PVI) using Lesion Size Index (LSI) algorithm-guided high-power short-duration (HPSD) radiofrequency ablation versus conventional radiofrequency ablation. Their findings indicate that HPSD ablation at 50 W is associated with significantly lower rates of redo procedures and pulmonary vein reconnection compared to conventional 30 W ablation, suggesting improved durability of the HPSD approach, although it also revealed higher reconnection rates in specific anatomical regions.
