“…In our study, the cardiac injury markers (troponin I, CK, and CK-MB) were significantly lower in the LBA group, similar to the results of Yano et al [ 14 ]. That was because the balloon contact area with the tissue during the CBA was wider than the linear lesions formed by the photonic energy delivery during the LBA [ 15 ].…”

Balloon ablation therapy has recently been used for atrial fibrillation (AF) ablation. Laser balloons possess the property in which the balloon size can be changed. Standard laser balloon ablation (Standard LBA) was followed by additional ablation using a maximally extended balloon (Extended LBA) and its lesion characteristics were compared to cryoballoon ablation (CBA), another balloon technology. From June 2020 to July 2021, patients with paroxysmal AF who underwent an initial pulmonary vein (PV) isolation were enrolled. Sixty-five patients with paroxysmal AF were included, 32 in the LBA and 33 in the CBA group. To measure the isolated surface area after the ablation procedures, left atrial voltage mapping was performed after Standard LBA, Extended LBA, and CBA. The baseline patient characteristics did not differ between LBA and CBA. Extended LBA could successfully increase the isolated area more than Standard LBA for all four PVs. Compared to CBA, the isolated area of both superior PVs was significantly greater with Extended LBA (left superior PV: 8.5 ± 2.1 vs 7.3 ± 2.4, p = 0.04, right superior PV: 11.4 ± 3.7 vs 8.7 ± 2.7, p < 0.01), and thus the non-isolated posterior wall (PW) was smaller (8.5 ± 3.4 vs 12.4 ± 3.3, p < 0.01). Nevertheless, changes in the cardiac injury markers were significantly lower with LBA than CBA. There was no significant correlation between the cardiac injury level and isolated area in both groups. In conclusion, Extended LBA exhibited a significantly greater isolation of both superior PVs and resulted in a smaller non-isolated PW, but the cardiac injury markers were significantly suppressed as compared to CBA.

“…PerAF patients who underwent an initial ablation were enrolled between May 2017 and Sepember 2020 from the ORAF (Osaka Rosai Atrial Fibrillation ablation) registry [14] , [15] , [16] . In the present study, PerAF was defined as AF persisting for more than 1 week.…”

“…Anticoagulation therapy was started at least 3 weeks before the ablation procedure. Details of the catheter ablation in our laboratory have been published previously [14] , [15] , [16] . One circular mapping catheter was deployed in the superior and inferior pulmonary veins and the left-sided then right-sided ipsilateral pulmonary veins (PVs) were circumferentially ablated guided by three-dimensional left atrium mapping (CARTO3, Biosense-Webster, Diamond Bar, CA, USA).…”

“…Although RF is energy normally in RFCA, other energies have been studied as possible alternatives, such as microwave [ 65 , 66 ] and High-Intensity Focused Ultrasound (HIFU) [ 67 , 68 ]. Cryoablation and laser applied by means of a balloon are currently an alternative to RF in pulmonary vein isolation to treat atrial fibrillation [69] . Hot balloons have also been used for this goal [70] .…”
