Hybrid Ablation: Two-Center Experience

Abstract

Despite the advantages of thoracoscopic radiofrequency ablation, a significant number of recurrences are observed in patient subgroups with heart failure (both preserved and reduced ejection fraction) and long-standing atrial fibrillation (AF). Our study presents the technical description and results of thoracoscopic ablation in 165 patients, 36 of whom underwent a biatrial ablation scheme. Additionally, 22 patients underwent a hybrid approach, combining thoracoscopic and endocardial ablation. In our study, the most common gap of the epicardial isolation line was the anterior segment of the antral part of the right pulmonary veins, where additional ablation was required in 13 (59.1%) patients. The hybrid approach improves treatment efficacy in persistent AF and high-risk patient groups, demonstrating a favorable safety profile and comprehensive treatment solution.
