Ablation of paroxysmal atrial fibrillation using a secondâgeneration cryoballoon catheter or contactâforce sensing radiofrequency ablation catheter: A comparison of costs and longâterm clinical outcomes
IntroductionAlthough noninferiority of cryoballoon ablation (CBA) and radiofrequency catheter ablation for antral pulmonary vein isolation (APVI) has been reported in patients with paroxysmal atrial fibrillation (PAF), it is not clear whether contact force sensing (CFâRFA) and CBA with the secondâgeneration catheter have similar procedural costs and longâterm outcomes. The objective of this study is to compare the longâterm efficacy and cost implications of CBA and CFâRFA in patients with PAF.Methods and resultsA first APVI was performed in 146 consecutive patients (age: 63 ± 10 years, men: 95 [65%], left atrial diameter: 42 ± 6 mm) with PAF using CBA (71) or CFâRFA (75). Clinical outcomes and procedural costs were compared. The mean procedure time was significantly shorter with CBA than with CFâRFA (98 ± 39 vs. 158 ± 47 minutes, P < 0.0001). Despite a higher equipment cost in the CBA than the CFâRFA group, the total procedure cost was similar between the two groups (P = 0.26), primarily driven by a shorter procedure duration that resulted in a lower anesthesia cost. At 25 ± 5 months after a single ablation procedure, 51 patients (72%) in the CBA, and 55 patients (73%) in the CFâRFA groups remained free from atrial arrhythmias without antiarrhythmic drug therapy (P = 0.84).ConclusionsThe procedure duration was approximately 60 minutes shorter with CBA than CFâRFA. The procedural costs were similar with both approaches. At 2 years after a single procedure, CBA and CFâRFA have similar singleâprocedure efficacies of 72â73%.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/142442/1/jce13378_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/142442/2/jce13378.pd
