“…For substrate modification, electrogram guided ablation was performed with the endpoint AF CL prolongation or AF termination (into AT or sinus rhythm), as described before . Linear lesions including a modified anterior line and/or a roofline were deployed in case of extensive LVA on the anterior wall and/or roof, or in case of subsequent macroreentries . If sinus rhythm was not achieved after these steps, direct current cardioversion was performed at the end of the procedure.…”

“…At the end of the procedure in all patients, a complete pulmonary vein isolation and in case of additional linear lesions using differential pacing a bidirectional block of all lines could be confirmed. 13…”

Aims Early recurrences (ER) of atrial arrhythmias are common after catheter ablation of atrial fibrillation (AF). The significance of these ER is controversial. Based on data of continuous cardiac monitoring, we sought to investigate the characteristics of ER and their impact on late recurrences (LR) during follow‐up. Methods One hundred twenty‐six patients with paroxysmal (49%) or persistent (51%) AF underwent an AF ablation with subsequent implantation of implantable loop recorder. Follow up was 12 months using remote monitoring. All atrial arrhythmia (AF or atrial tachycardia‐AT‐) episodes >30 seconds. within the 3‐month blanking period were considered and the AF burden evaluated every 3 months. Results Within the 3‐months blanking period, 72 patients (57%) experienced an AF/AT recurrence. Survival free from any arrhythmia recurrence during follow‐up was 40% in patients with ER vs 69% in those without ER. AF burden during the blanking period and timing of ER correlated significantly with LR at 12 months (area under curve = 0.74, P < .0001 and .831, P < .0001). An AF burden ≥0.5% and ER after 74 days predicted LR (sensitivity 60%, specificity 84.4%; sensitivity 75.6%, specificity 90.3%). In cox regression analysis, AF burden ≥0.5% and ER after 74 days were independently associated with LR. Conclusion Continuous cardiac monitoring after AF ablation provides important information regarding early recurrence episodes and their prognostic impact. A cut‐off of 74 days for the blanking period seems to better differentiate patients with a good or a poor long‐term outcome. An AF burden ≥0.5% during the 3 months postablation is predictive for late arrhythmia recurrences.

“…The roof line was deployed between both upper pulmonary veins. A modified anterior line (MAL) was performed as described earlier by our group . Briefly, RF ablation was started with an atrioventricular electrogram ratio of 1:2 at the anterior part of the mitral annulus.…”

“…All patients who did not convert in SR after ablation underwent a DCC at the end of the procedure. In SR, all veins were checked again to confirm isolation and LL were tested for bidirectional block using differential pacing as described before . Briefly, the MAL conduction block was assessed by pacing from the LAA and septally to the line while observing CS activation sequence, and activation times between the CS and LAA, respectively.…”
