Abstract Aims Restoring sinus rhythm (SR) by ablation alone is an endpoint used in radiofrequency (RF) ablation for long-standing persistent atrial fibrillation (AF) but not with cryotherapy. The simultaneous use of two cryotherapy catheters can improve ablation efficiency; we compared this with RF ablation in chronic persistent AF aiming for termination to SR by ablation alone. Methods and results Consecutive patients undergoing their first ablation for persistent AF of >6 months duration were screened. A total of 100 participants were randomized 1:1 to multi-catheter cryotherapy or RF. For cryotherapy, a 28-mm Arctic Front Advance was used in tandem with focal cryoablation catheters. Open-irrigated, non-force sensing catheters were used in the RF group with a 3D mapping system. Pulmonary vein (PV) isolation and non-PV triggers were targeted. Participants were followed up at 6 and 12 months, then yearly. Acute PVI was achieved in all cases. More patients in the multi-catheter cryotherapy group were restored to SR by ablation alone, with a shorter procedure duration. Sinus rhythm continued to the last available follow-up in 16/49 patients (33%) in the multi-catheter at 3.0 ± 1.6 years post-ablation and in 12/50 patients (24%) in the RF group at 4.0 ± 1.2 years post-ablation. The yearly rate of arrhythmia recurrence was similar. Conclusion Multi-catheter cryotherapy can restore SR by ablation alone in more cases and more quickly than RF ablation. Long-term success is difficult to achieve by either methods and is similar with both.

Abstract Funding Acknowledgements Type of funding sources: None. Background. Knowledge about the association between symptoms and rhythm status (symptom-rhythm correlation) has potential clinical implications as it may identify patients with atrial fibrillation (AF) who profit from rhythm control in regard to reduction in symptom burden and improvement in quality of life. However, standardized strategies to assess symptom-rhythm correlation in AF patients are currently not available. Purpose. This study aimed to assess symptom-rhythm correlation in patients with persistent AF using electrical cardioversion (ECV) as a diagnostic probe. Methods. We used ECV to examine symptom-rhythm correlation in 81 patients with persistent AF. The presence of self-reported symptoms before ECV and at the first outpatient AF clinic follow-up visit (within 1-month) was assessed to determine the prevalence of a symptom-rhythm correlation (defined as self-reported symptoms present during AF and absent in sinus rhythm or absent in AF and yet relief during sinus rhythm). The symptom-rhythm correlation was absent in patients with symptoms before ECV who remained symptomatic during sinus or in patients with symptoms prior to ECV and without symptoms in AF after ECV. Asymptomatic patients before ECV with or without symptoms in AF or sinus rhythm afterwards had no symptom-rhythm correlation as well. The symptom-rhythm correlation was unevaluable in patients who were symptomatic in AF before ECV and at the first outpatient AF clinic follow-up visit. In addition, predominant self-reported symptoms (symptoms with highest self-reported symptom burden) were assessed to evaluate the symptom patterns around ECV. Intra-individually variable symptom patterns were defined as changes in predominant self-reported symptoms within patients around ECV. Results. Symptom-rhythm correlation was assessed in all patients. Only in 18 patients (22%), a symptom-rhythm correlation could be documented. Twenty-eight patients (35%) did not show any symptom-rhythm correlation and 35 patients (43%) had an unevaluable symptom-rhythm correlation as these patients were in symptomatic AF both at baseline and at the first outpatient AF clinic follow-up visit. Importantly, self-reported symptom patterns around ECV were intra-individually variable in 10 patients (12%) without symptom-rhythm correlation (of which 9 patients (11%) had AF recurrence) and in 2 patients (2%) with an unevaluable symptom-rhythm correlation. Conclusions. In patients with persistent AF, the prevalence of a symptom-rhythm correlation around ECV is low, but ECV often changes symptom pattern. Further studies are warranted to identify more optimal strategies to assess symptom-rhythm correlation in patients with persistent AF. Abstract Figure. Symptom-rhythm correlation and patterns

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.

Electrical Cardioversion

In the present retrospective cohort study, we have evaluated the missed or delayed atrial mechanical recovery in a population of patients with persistent or long-lasting persistent AF who achieved restoration of sinus rhythm on the ECG by electrical cardioversion (ECV).  The endpoint of our   study was   the failure to recover the normal mechanics of the left atrium.  Inclusion criterion was the persistent or long-lasting persistent atrial fibrillation successfully treated by means of    ECV , provided that  a pertinent documentation  was made available, comprising ECG, conventional 2D echo-color-Doppler and   speckle tracking echocardiography(STE)  evaluation, with also a STE assessment  of the atria at the days 1, 30 and 90  from the ECV freely available within  the clinical record  of the patient. Out of a total of 80 patients with persistent or long-standing persistent AF, retrospectively enrolled, as many as  22.5% of them did not achieve the normalization of their  atrial STE profile, even though they had been converted to sinus rhythm on the ECG by means of ECV.  The building of ROC curves allowed us to establish that early measurements of global atrial strain could serve to predict  both the risk of failure to recover the atrial mechanical function and the one of AF relapses over a 12 month follow-up. The   values of 18% and 17% were also calculated  to serve as cut off values, respectively,  for the risk  of atrial mechanical dysfunction and for the risk of AF  relapses over a 12 month follow-up. Failure to recover the atrial reservoir function can accompany a restoration of sinus rhythm on the ECG in patients with long-standing persistent AF. In this case, a serial STE evaluation could be useful to evaluate the atrial hypofunction over time.

AbstractThe optimal ablation strategy for persistent atrial fibrillation (PsAF) remains to be defined. We sought to compare very long-term outcomes between linear ablation and electrogram (EGM)-guided ablation for PsAF. In a retrospective analysis, long-term arrhythmia-free survival compared between two propensity-score matched cohorts, one with pulmonary vein isolation (PVI) and linear ablation including roof/mitral isthmus line (LINE-group, n = 52) and one with PVI and EGM-guided ablation (EGM-group; n = 52). Overall, 99% of patients underwent successful PVI. Complete block following linear ablation was achieved for 94% of roof lines and 81% of mitral lines (both lines blocked in 75%). AF termination by EGM-guided ablation was accomplished in 40% of patients. Non-PV foci were targeted in 7 (13%) in the LINE-group and 5 (10%) patients in the EGM-group (p = 0.76). During 100 ± 28 months of follow-up, linear ablation was associated with superior arrhythmia-free survival after the initial and last procedure (1.8 ± 0.9 procedures) compared with EGM-group (Logrank test: p = 0.0001 and p = 0.045, respectively). In multivariable analysis, longer AF duration and EGM-guided ablation remained as independent predictors of atrial arrhythmia recurrence. Linear ablation might be a more effective complementary technique to PVI than EGM-guided ablation for PsAF ablation.
