Aim. To estimate the clinical success of cryoballoon pulmonary vein isolation (PVI).Methods.230 patients (males: 49.6%, mean age 57 (53; 62) with symptomatic paroxysmal and persistent atrial fibrillation (AF) resistant to antiarrhythmic therapy were included in a single-center prospective study. The patients were randomized into 2 groups to undergo either cryoballoon ablation (n = 122) or radiofrequency (RF) (n = 108) ablation. Both groups were comparable in baseline parameters. The follow-up period was 12 months. Clinical outcomes were estimated with the use of a three-stage scale. The rates of cardiovascular rehospitalizations, direct-current cardioversions and repeated ablations during were estimated within the follow-up. The quality of life (QoL) in the cryoablation group was measured using the AFEQT scale.Results.77% (n = 94) of patients in the cryoballoon ablation group and 71.3% (n = 77) of patients in the RF group (р = 0.71) demonstrated reported the optimal clinical effects. Both groups, cryo ablation and RF ablation, had similar rates of cardiovascular hospitalizations (23.8 vs 28.7%, OR 0.8, 95% CI 0.4–1.4; р = 0.39), direct-current cardioversions (12.3 vs 17.6%, OR 0.7, 95% CI 0.3–1.4; р = 0.26) and repeated ablations (9.8–11.1%, OR 0.9, 95% CI 0.4–2.0; р = 0.75). The patients treated with cryoballoon as opposed to RF ablation had significantly more successful usage of “pill-in-pocket” strategy – 14.8 vs 6.5% (OR 2.5, 95% CI 1.01–6.2; р = 0.04). Significant improvements of the QoL parameters with strong size effect have been found in the cryoablation group, i.e. global score (GS) increased by 8.9±6.9 (95% CI 6.6–10.1; dCohen 1.2; р<0.001), symptoms (S) – by 8.3±7.9 (95% CI 4.2–8.8; dCohen 1.5; р<0.001), daily activities (DA) – by 10.0±6.9 (95% CI = 6.4–10.6; dCohen 0.9; р<0.001), treatment concerns (TC) – by 5.5±6.0 (95% CI 6.3–9.2; dCohen 1.2; р<0.001) and treatment satisfaction (TS) – by 5.5±6.0 (95% CI 5.4–9.8; dCohen 0.9; р<0.001).Conclusion.The both catheter-based technologies had comparable clinical success. Cryoablation was characterized by improvement in all QoL parameters based on the AFEQT score.
