“…Thus, the surgical portion of the procedure was converted to use a bipolar RF clamp (AtriCure Inc., West Chester, OH), which had been shown to be more effective. 1376 This approach provided improved results, and in most cases, gaps in surgical lesions could be completed by endocardial catheter ablation during the same procedure. 608 A sequential hybrid approach was subsequently developed.…”

“…In our centre, bipolar radiofrequency energy has been favoured over other sources, because it can create rapid trans-mural lesions in a reliable and consistent manner (Prasad et al, 2002). These devices use online measurement of conductance as a surrogate for trans-murality.…”

“…Beyond the ''cut and sew'' surgical technique, the conventional use of limited linear and spot ablations in these complex cases, frequently involving suboptimal devices and energy delivery methods, are well-recognized for their deficiencies. 6,7 The epicardial ablation technique described in this study, in combination with the endocardial component, is designed to circumvent many of these limitations and to target in particular an anatomical area recognized as being a dominant and concentrated site of arrhythmia substrate.…”

ABSTRACT. Here, we report intermediate follow-up details after using a technique of confluent posterior left atrial wall epicardial ablation designed to eliminate both existing and future atrial fibrillation (AF) substrates. The method is part of the Convergent hybrid procedure for AF ablation. In this study, multiple confluent epicardial ablations with radiofrequency energy were delivered, spanning the vertical and transverse dimensions of the posterior left atrium, along with facilitated pulmonary vein isolation (PVI). Endocardial mapping and ablation were performed to complete PVI and to ablate the cavotricuspid isthmus. All patients were followed clinically and using two-to-four weeks of continuous monitoring at six, 12, and 24 months, respectively. The average length of follow-up was 488 days. Of the 57 largely unselected patients with persistent or longstanding persistent AF (NPAF), mean duration of AF was 5.6 years. Single procedure freedom from AF through 24 months was 64.5%, and that for all arrhythmias, was 58.9%. Sixty-eight percent of patients were off antiarrhythmic drugs. Four patients (7%) required a second endocardial ablation procedure. A sub-analysis of the observed arrhythmia burden present through follow-up showed this to be small (ie, o1%) in the majority of patients involved in this study. In conclusion, the extended posterior left atrial wall ablation technique discussed here, as part of the Convergent hybrid method, achieved notable single-procedure success in a particularly challenging series of patients with NPAF.
