AIMS: Pre-procedural identification of patients with atrial fibrillation (AF) who will remain free from AF after pulmonary vein isolation (PVI) remains challenging. Clinical risk scores, including CHADS2, CHA2DS2-VASc, R2CHADS2, and HATCH scores show modest discriminative ability with respect to AF recurrence. B-type natriuretic peptide (BNP) is associated with risk for AF and AF recurrence but is not currently included in existing AF risk scores. We sought to evaluate the incremental benefit of adding pre-operative BNP to existing risk scores in predicting AF recurrence within 6-months after PVI. METHODS AND RESULTS: One hundred and fifty one patients (105 men, age 60 ± 10 years) with paroxysmal or persistent AF underwent an index PVI procedure between 2010-2014. Seventy-seven patients had an AF recurrence (51%) over the 6-month follow-up period. BNP level of >100 units was significantly associated with 6-month AF recurrence in univariate models (p<0.001). A composite risk score including BNP to the existing scores significantly improved their predictive value and net AF recurrence reclassification (net reclassification index, 63.4%; p<0.001) (Table 1). CONCLUSIONS: Addition of BNP to existing AF risk scores enhanced their predictive value and discriminative ability in predicting AF recurrence after PVI. Further research is needed including large and diverse cohorts of patients undergoing ablation and monitored for AF recurrence over extended periods to further validate the performance of this composite score.

Abstract Funding Acknowledgements Type of funding sources: None. Background/Introduction: A significant number of patients experience recurrent atrial fibrillation (AF) after ablation. Predicting who will or will not benefit from AF ablation is challenging. Although various risk scores have been designed to predict outcomes after AF ablation, comparative data are sparse and external risk score validation is often lacking. Purpose In this study, we aimed to compare ten previously described risk scores with regard to their predictive value for post-ablation AF recurrence and procedural complications. Methods A total of 482 AF patients (37% non-paroxysmal AF, 66% male, mean age 62 ± 9 years) undergoing initial radiofrequency pulmonary vein isolation (RF-PVI) were included in the present analysis. Prior to ablation, all patients underwent both transthoracic echocardiography and either cardiac computed tomography imaging or cardiac magnetic resonance imaging. The following risk scores were calculated for each patient: APPLE, ATLAS, BASE-AF2, CAAP-AF, CHADS2, CHA2DS2-VASc, DR-FLASH, HATCH, LAGO and MB-LATER. The predictive performance of the risk scores for AF recurrence and complications were assessed separately by receiver operating characteristic (ROC) curves. Results Median follow-up was 16 (12-31) months. AF recurrence after the 90-day blanking period was observed in 199 patients (41%), occurring after a median of 183 (124-360) days after ablation. Overall procedural adverse event rate was 6%. The HATCH score was the only score without predictive value for recurrent AF after ablation (area under curve [AUC] 0.545). All other investigated scores demonstrated statistically significant but poor predictive value for recurrent AF after ablation (AUC 0.553-0.669). CHA2DS2-VASc and CAAP-AF were the only risk scores with predictive value for procedural complications (AUC 0.616, p = 0.043; AUC 0.615, p = 0.044; respectively). ROC curve analyses of the studied risk scores for the prediction of AF recurrence and complications are shown in Figure. Conclusion Currently available risk scores perform poorly in predicting outcomes after RF-PVI. These data suggest that the utility of these scores for clinical decision-making is limited.

Abstract Background Cryoballoon (CB) pulmonary vein isolation (PVI) is increasingly being used in patients (pts) with persistent atrial fibrillation (AF). However, there are limited data about the pattern of atrial fibrillation (AF) recurrence in these pts. Objective To assess, using an implantable loop recorder (ILR), the patterns of AF recurrence following CB PVI in pts with persistent atrial fibrillation. Methods We enrolled consecutive pts with persistent AF ablation undergoing their first CB ablation. Other cavotricuspid isthmus ablation when indicated, no other ablation was performed. A Reveal LINQ ILR (Medtronic) was implanted <3 months following ablation; all pts had a minimum of 1-year follow-up. The recurrence of any atrial arrhythmia was determined and adjudicated; 4 distinct AF patterns were characterized (Figure). Results We studied 64 pts (66±9 years; 50 [78%] male; CHA2DS2-VASc 2.6±1.9) with persistent AF; 52 (81%) pts were on an antiarrhythmic drug (AAD) peri-ablation. During 803±361 days of follow-up, 33 (52%) pts had their 1st AF recurrence 91–365 days post-ablation and another 17 (27%) pts had their 1st AF recurrence >365 days post-ablation. No AF was seen in 14 (31%) pts. Most pts (33 of 50, 66%) with AF recurrence presented with 1 of 3 distinct patterns of paroxysmal AF (Figure), which ranged from 22 min to 124 hours. In 2/3 of these pts, all AF recurrences lasted <24 hours. Only 17 (34%) pts recurred with persistent AF. Conclusion Following single CB PVI, most pts with persistent AF remained free of persistent AF during long-term follow-up. Most pts with recurrent AF have 1 of 3 distinct patterns with episodes commonly last <24 hours. These data suggest that CB PVI ablation may halt AF progression in pts initially presenting with persistent AF.

Introduction: Cryoballoon pulmonary vein isolation (PVI) has emerged as an alternative to radiofrequency PVI for the treatment of paroxysmal atrial fibrillation (AF). The optimal ablation strategy for patients with persistent AF is unclear, as data on Cryoballoon PVI alone are limited. Methods: We analyzed a prospective registry of consecutive patients with persistent AF who underwent Cryoballoon PVI at a single center between 2011 and 2014. Patients were assessed for AF recurrence (including any atrial arrhythmia) after a 3 month blanking period at 6 months, 1 year, 2 years, and as needed for symptoms post PVI. Recurrence was based on typical symptoms or ECG/ event monitor evidence of AF. Kaplan-Meier analysis was used to estimate AF-free survival. Results: The 69 patients who underwent Cryoballoon PVI were aged 59 ± 8 years, 86% male, 54% HTN, had a CHADS2-VASC score 1.6 ± 1.2, and had a LA dimension 4.5 ± 0.6 cm. The AF recurrence-free rate at 1-year post-procedure was 59%. Overall, AF-free survival was 50% at the mean follow-up of 607 days. In comparing patients with persistent AF duration <1 year vs. >1 year, there was a trend toward greater AF recurrence-free rates in the <1 year group (66% vs 55%, p=0.09) Conclusions: Cryoballoon PVI appears to be an effective initial strategy in treating persistent AF, with an AF recurrence-free rate of 59% at 1 year.

Abstract Funding Acknowledgements Karolina Weinmann was supported by the Hertha-Nathorff fellowship from Ulm University Background - Obesity is a known risk factor for the incidence and persistence of atrial fibrillation. Many interventional studies proved losing weight correlates with less atrial fibrillation (AF) burden. Purpose – We investigated the influence of overweight and obesity on baseline characteristics, procedural values and outcome after cryoballoon pulmonary vein isolation (cryoballoon PVI). Methods – We investigated 575 patients undergoing cryoballoon PVI at our Medical Center. 142 patients were classified as normal with a body mass index (BMI) of 18.5 – 24.9 kg/m², 239 patients presented overweight with a BMI of 25.0 – 29.9 kg/m² and 194 patients were obese with a BMI over 30.0. We compared the baseline characteristics, the procedural and outcome data of these patients. Results – Comparing baseline characteristics of overweight and obese patients to normal weight patients, obese show the highest portion in hypertension (obese vs. normal: 86.1% vs. 68.3%, p &lt; 0.001), diabetes (26.8% vs. 14.8%, p &lt; 0.05), OSAS (17.0% vs. 2.1%, p &lt; 0.001) and left atrial (LA) diameter (44.6 ± 10.8mm vs. 41.3 ± 12.7mm, p &lt; 0.05). Comparison of procedure duration, fluoroscopy time and area dose product (Gy*cm²), only the area dose product shows a significantly higher value in the overweight and obese patients (p &lt; 0.001). Moreover, comparing the duration of ablation, time to isolation per pulmonary vein between the three groups, the overweight and obese patients show a significantly longer duration of ablation at the RSPV and the time to isolation is significantly higher at the LSPV. Mean follow-up period in our cohort is 517.3 ± 461.3 days (1.4 ± 1.3 years). Kaplan-Meier estimation shows no significant difference between freedom from AT/AF recurrence comparing normal weight, overweight and obese patients (Log-rank p = 0.6). After one year follow-up, 70% of normal weight patients show freedom from atrial arrhythmia recurrence and 69% of overweight patients.  Obese patients have a fraction of 75% of freedom from AT/AF recurrence after one year. Comparing the two years follow-up values 56% of the normal BMI patients, 54% of the overweight patients and 62% of obese patients are free from arrhythmia recurrence. Conclusion – Cryoballoon PVI procedure in obese and overweight patients is a feasible treatment, however the radiation exposure is higher compared to normal weight. Evaluating outcomes, no difference in recurrence of AF was detected between normal, overweight and obese patients after cryoballoon PVI.

Background: In patients undergoing paroxysmal atrial fibrillation (PAF) ablation, pulmonary vein isolation (PVI) alone fails in maintaining sinus rhythm in up to one third of patients after a first catheter ablation. Epicardial adipose tissue (EAT), as an endocrine-active organ, could play a role in the recurrence of AF after catheter ablation. Objective: To evaluate the predictive value of clinical, echocardiographic, biological parameters and epicardial fat density measured by computed tomography scan (CT-scan) on AF recurrence in PAF patients who underwent a first pulmonary vein isolation procedure using radiofrequency (RF). Methods: This monocentric retrospective study included all patients undergoing first-time RF PAF ablation at the Nancy University Hospital between March 2015 and December 2018 with one-year follow-up. Results: 389 patients were included, of whom 128 (32.9%) had AF recurrence at one-year follow-up. Neither total-EAT volume (88.6 ± 37.2 cm3 vs. 91.4 ± 40.5 cm3, p = 0.519), nor total-EAT radiodensity (−98.8 ± 4.1 HU vs. −98.8 ± 3.8 HU, p = 0.892) and left atrium-EAT radiodensity (−93.7 ± 4.3 HU vs. −93.4 ± 6.0 HU, p = 0.556) were significantly associated with AF recurrence after PAF ablation. In multivariate analysis, previous cavo-tricuspid isthmus (CTI) ablation, ablation procedure duration, BNP and triglyceride levels remained independently associated with AF recurrence after catheter ablation at 12-months follow-up. Conclusion: Contrary to persistent AF, EAT parameters are not associated with AF recurrence after paroxysmal AF ablation. Thus, the role of the metabolic atrial substrate in PAF pathophysiology appears less obvious than in persistent AF.

Abstract Aims Catheter ablation of paroxysmal atrial fibrillation (AF) reduces AF recurrence, AF burden, and improves quality of life. Data on clinical and procedural predictors of arrhythmia recurrence are scarce and are flawed by the high rate of pulmonary vein reconnection evidenced during repeat procedures after pulmonary vein isolation (PVI). In this study, we identified clinical and procedural predictors for AF recurrence 1 year after CLOSE-guided PVI, as this strategy has been associated with an increased PVI durability. Methods and results Patients with paroxysmal AF, who received CLOSE-guided PVI and who participated in a prospective trial in our centre, were included in this study. Uni- and multivariate models were plotted to find clinical and procedural predictors for AF recurrence within 1 year. Three hundred twenty-five patients with a mean age of 63 years (CHA2DS2VASc 1 [1–3], left atrium diameter 41 ± 6 mm) were included. About 60.9% were male individuals. After 1 year, AF recurrence occurred in 10.5% of patients. In a binary logistic regression analysis, the diagnosis-to-ablation time (DAT) was found to be the strongest predictor of AF recurrence (P = 0.011). Diagnosis-to-ablation time ≥1 year was associated with a nearly two-fold increased risk for developing AF recurrence. Conclusion The DAT is the most important predictor of arrhythmia recurrence in low-risk patients treated with durable pulmonary vein isolation for paroxysmal AF. Whether reducing the DAT could improve long-term outcomes should be investigated in another trial.
