Background: Cryoballoon ablation is an established procedure for atrial fibrillation (AF). Patient with vena cava filter undergoing pulmonary vein isolation (PVI) were seldom reported.Case presentation: We describe an AF ablation technique using the second generation cryoballoon in a patient after vena cava filter implantation. All pulmonary veins were successfully isolated without complication.Conclusions: For AF patient with previously implanted vena cava filter, cryoballoon based PVI appears feasible and safe.

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.

IntroductionPulmonary vein isolation (PVI) is an important treatment for atrial fibrillation (AF). However, many patients need more than one procedure to maintain long-term sinus rhythm. Even after two PVIs some may suffer from AF recurrences. We aimed to identify characteristics of patients who fail after two PVI procedures.Methods and resultsWe included 557 consecutive patients undergoing a first PVI procedure with a second-generation 28 mm cryoballoon. Follow-up procedures were performed using radiofrequency ablation targeting reconnected PVs only. Recurrent AF was defined as any episode of AF lasting >30 s on ECG or 24 hour Holter monitoring performed at 3, 6 and 12 months post procedure. Mean age was 59.1±10.2 years, 383 (68.8%) were male, 448 (80.4%) had paroxysmal AF and the most common underlying condition was hypertension (36.6%). A total of 140/557 (25.1%) patients underwent redo procedure with PVI only. Of these patients 45 (32.4%) had recurrence of AF. These patients were comparable regarding age and sex to those in sinus rhythm after one or two procedures. Multivariate logistic regression showed that non-paroxysmal AF (OR 1.08 (95% CI 1.01 to 1.15), estimated glomerular filtration rate (OR 0.96, 95% CI 0.94 to 0.99), bundle branch block (OR 4.17, 95% CI 1.38 to 12.58), heart failure (OR 4.17, 95% CI 1.38 to 12.58) and Left Atrium Volume Index (OR 1.04, 95% CI 1.01 to 1.08) were associated with AF recurrence after two PVIs. The area under the curve for the identified risk factors was 0.74.ConclusionsUsing a PVI-only approach, recurrence of AF after two AF ablation procedures is associated with more advanced underlying disease and persistent types of AF.
