“…Successful ablation depends on achieving lesions that are reliably transmural. 648,649 The conventional approach employed by cardiac electrophysiologists to reach the goal of AF ablation is RF energy delivery by way of a transvenous electrode catheter. RF energy achieves myocardial ablation by causing resistive heating of the tissue with subsequent heat conduction to deeper tissue layers.…”

“…The atrial tachyarrhythmias (including atrial flutter), after the AF ablation, are primarily related to incomplete ablation lines and that did not reach the entire tissue thickness 20,21 . The use of bipolar RF technology reduces this risk by conceptually guaranteeing the "transmurality " of the lesions.…”

“…Previous studies have shown that continuous, transmural ablation lines are essential to reliably block electrical propagation. 14,15 Residual gaps caused by incomplete lesions, even as small as 1.1 mm, are still able to allow for effective conduction both of normal paced rhythm or AF. 14 This may result in the postoperative AF recurrence.…”

BackgroundOur previous study reported a modified endoscopic procedure for nonvalvular atrial fibrillation (AF) that requires only 3 ports in the left chest wall.HypothesisCertain preoperative variables might be predictive risk factors for AF recurrence among patients who underwent this procedure.MethodsFrom October 2010 to April 2014, 114 patients with either paroxysmal AF (PAF) or nonparoxysmal AF (non‐PAF) underwent the procedure and completed postoperative cardiac‐rhythm measurement via electrocardiography and Holter monitoring. Univariate and multivariate analyses of the possible AF‐related risk factors were conducted.ResultsDuring 2‐year follow‐up, 99 of 114 patients (86.8%) were free from atrial tachyarrhythmia. Results from univariate analyses showed that AF duration, left atrial diameter (LAD), left atrial minimum volume, left atrial empty fraction, left atrial expansion index, and left atrial active empty fraction (LAAEF) were significantly associated with postoperative AF recurrence. Results from multivariate analyses showed that AF duration (odds ratio [OR]: 1.194, 95% CI: 1.063‐1.340, P = 0.003), LAD (OR: 1.101, 95% CI: 1.005‐1.205, P = 0.039), and LAAEF (OR: 0.490, 95% CI: 0.277‐0.865, P = 0.014) were independent risk factors. There was no difference in AF recurrence between patients with PAF and non‐PAF (P = 0.250).ConclusionsOur 2‐year follow‐up study suggested that low LAAEF, long AF duration, and large LAD might be potential predictive risk factors for AF recurrence. Patients with PAF and non‐PAF had a similar AF recurrence rate after modified endoscopic ablation.
