Third-generation laser balloon ablation: rapid mode applicability is associated with shorter time to pulmonary vein isolation

Abstract Background The rapid mode feature implemented in the latest version of the laser balloon system (LB3, HeartLight, X3, Cardiofocus) offers an automated continuous 360° lesion for pulmonary vein isolation (PVI). However, data on its clinical applicability and the potential reduction of proced...

description Abstract Background The rapid mode feature implemented in the latest version of the laser balloon system (LB3, HeartLight, X3, Cardiofocus) offers an automated continuous 360° lesion for pulmonary vein isolation (PVI). However, data on its clinical applicability and the potential reduction of procedural times are not yet available. Purpose To explore the use of the rapid mode and its association with PV total and fluoroscopy times in our initial experience with LB3. Methods This analysis included consecutive patients who underwent PVI procedure with LB3. We attempted to perform a complete circular ablation line using the rapid mode at 13 W, but if needed to achieve successful isolation, rapid mode was interrupted and manual mode (5.5–8.5 W) applications were used. The percentage of rapid mode use on the 360° lesion was measured for each PV. Total and fluoroscopy times to complete PVI were also collected. Results A total of 110 PVs were identified in 27 LB3 procedures and successfully isolated with a mean procedural time of 85±31 min. Sixty (55%) PVs were treated by using rapid mode for more than 50% (180°) lesion and 13 (12%) of them had a pure rapid mode ablation (without necessity of manual mode applications). Right inferior PV had the highest use of rapid mode (median value 70%). The main reasons for manual applications were poor PV occlusion, imperfect ostium visualization and presence of blood. PVs with >50% rapid mode use were treated in a significantly shorter time (21.2±13.7 vs 26.8±12.4, p=0.043). Fluoroscopy time did not differ significantly (4.7±4.2 vs 5.4±4.9, p=0.48). Three pinhole balloon ruptures were observed during rapid mode energy application in the second, third and twenty-fifth procedure. No other complications occurred. Conclusions Few PVs could be isolated using pure rapid mode; however, its applicability for more than 50% lesion was observed more frequently and significantly reduced the time to isolation.
