“…The HBA group had higher rates of TUA than the CBA group, and their sites were prominently distributed on the left side of PVs, especially at LSPV, while a dominant TUA site by CBA compared to HBA was RIPV. These findings were similar to those of previous studies indicating LSPV by HBA and RIPV by CBA as dominant TUA sites 7,8 . The reason that the different TUA sites were caused by HBA and CBA was not clarified from the present study.…”

“…The high TUA rate by HBA, therefore, should be reduced. Previous reports indicated the LSPV as a dominant TUA site by HBA 7,8 . HBA performed at a balloon temperature of 73°C yielded a lower TUA rate than that at 70°C.…”

“…The inclusion of early cases with old cases at our facilities might have influenced the high TUA rate. The lower TUA rate associated with HBA at 73°C than at 70°C might partly be attributable to the operators’ learning curves, 7 although previous reports demonstrated that the learning curve of HBA was less closely related with an acute success rate than that of CBA 8 . Further studies are needed to determine whether the ablation temperature affects the acute success rate to a greater extent than the learning curve of the operator.…”

“…However, there are no detailed data available to judge the efficacy or defects of HBA compared to those of CBA. The AF recurrence rate post‐HBA is low in the short term, 7 and both methods are associated with similar midterm AF recurrence rates 8 7,8 .…”

“…The AF recurrence rate post‐HBA is low in the short term, 7 and both methods are associated with similar midterm AF recurrence rates 8 7,8 . This study aimed to compare HBA and CBA with regard to PVI durability and TUA rate, using propensity score‐matched patients to account for the effects of covariates including PV anatomy.…”

Introduction: This study aimed to compare touch-up ablation (TUA) rates and pulmonary vein isolation (PVI) durability of hot balloon ablation (HBA) and cryoballoon ablation (CBA) in paroxysmal atrial fibrillation (PAF) patients.Methods: In total, 137 PAF patients were enrolled in the study. Among them, 59 underwent two HBA procedures at 6-month intervals and 78 patients underwent two CBA sessions, both regardless of atrial fibrillation recurrence. Propensity score matching was performed to estimate similar patient characteristics between the HBA and CBA groups.Results: Each group comprised of 46 matched patients for comparison. The TUA rate at the first session was higher for HBA (49 of 184 PVs) than for CBA (20 PVs) (P = .01), with the highest incidence at the left superior pulmonary vein (LSPV). The rates of PVI durability at the second session performed 7 months later were similar between HBA (168 of 184 PVs) and CBA (162 PVs) groups. The PVI durability rate at the TUA sites of the first session was higher for HBA than for CBA (41 of 49 PVs vs 10 PVs, respectively; P = .01). Fifty percent of the patients underwent HBA at 73°C for the LSPV. HBA performed at 73°C yielded a lower TUA rate than that at 70°C (16 of 23 PVs vs 7 of 23 PVs; P = .008).Conclusions: While PVI durability was similar between HBA and CBA, the TUA rate was higher for HBA than for CBA, especially on the LSPV. For LSPV, HBA at a balloon temperature of 73°C may reduce the TUA rate.
