This review provides a detailed, image-guided anatomical description of the hybrid ablation procedure for atrial fibrillation (AF), addressing a critical need for precise anatomical knowledge in cardiac surgery. Hybrid ablation merges the durability of epicardial surgical lesions with the precision of endocardial catheter mapping, offering superior efficacy for persistent AF compared to standalone approaches. The core of this paper is a step-by-step intraoperative guide through right and left thoracoscopy, detailing trocar placement, pericardial sac dissection, and crucially, the creation of surgical access through the transverse and oblique pericardial sinuses. High-quality perioperative images illustrate the dissection and ablation of key structures with emphasis on the clinical anatomy of these targets, explaining their role in arrhythmogenesis. Furthermore, the review highlights the anatomical rationale for specific surgical maneuvers. Finally, we identify significant gaps in anatomical evidence, particularly concerning the vasculature of the arrhythmogenic substrates, including pulmonary veins, vestigial fold, and left atrial appendage. This work serves as an essential anatomical atlas for cardiac surgeons and electrophysiologists, aiming to enhance the safety, efficacy, and understanding of the hybrid ablation procedure.
