Abstract
<p>Cryoballoon ablation (CBA) is emerging as an alternative to radiofrequency ablation and is used in both paroxysmal and persistent atrial fibrillation (AF) with promising results. The aim of this study is to characterize patients (P) submitted to CBA of AF in a tertiary center, and verify AF recurrence rates between P with persistent and paroxysmal AF in a 12-month follow-up period after CBA.</p> <p><strong>Methods: </strong>Retrospective analysis of 99 consecutive P submitted to AF using CBA. AF recurrence was documented with EKG, 24-h Holter monitoring, cardiac event recorder or pacemaker analysis in a 12-month follow-up period.</p> <p><strong>Results: </strong>60,6% of the P were male, with a mean age of 54<u>+</u>15 years and a body mass index (BMI) of 28<u>+</u>4. The mean left auricular (LA) volume (in cardiac computed tomography scan) was 104<u>+</u>39 mL, with structural heart disease in 13,1% of the cases. AF was paroxysmal in 78P (78.8%) and persistent in 21P (21.2%). There were no statistically significant differences in the baseline characteristics of both groups (age: 53<u>+</u>15 years vs. 59<u>+</u>11 years, p=0,088; LA volume: 101<u>+</u>37 mL vs. 114<u>+</u>46 mL, p=0.486; structural heart disease: 15.4% vs. 5%, p=0,201; BMI: 28<u>+</u>5 vs. 28<u>+</u>3, p=0.378; gender: 59% vs. 66% male, p=0.522, for paroxysmal and persistent AF, respectively). In a 12-month follow-up there was a 13% AF recurrence rate in all population, with persistent AF P showing a higher recurrence rate: 33,3% vs. 7,9% (OR 5.833, p=0,005).</p> <p><strong>Conclusion: </strong>In P who underwent CBA of AF, there was a total recurrence rate of AF of 13% in a 12-month follow up, with a higher risk of recurrence in persistent AF.</p>
