Abstract:
Objective:To determine the safety and efficacy of the modified off-pump biatrial mini-maze procedure to treat isolated atrial fibrillation.Methods:This study retrospectively included isolated atrial fibrillation patients who underwent the modified off-pump biatrial mini-maze procedure at the Department of Cardiothoracic Surgery, Zhongshan Hospital, Fudan University from January 2021 to December 2023. These patients underwent a mini-maze procedure using the Dallas lesion set protocol. A purse-string suture was then performed on the right atrium, and 4 ablation lesions were made to the superior vena cava, the inferior vena cava, the appendix of the right atrium and the tricuspid valve annulus from the purse-string suture point using the bipolar radiofrequency clamp. After the operation, the patients were followed up at 3, 6 and 12months and every year thereafter.Results:A total of 301 patients were followed up. There were no deaths or strokes. A follow-up at intervals of 3, 6, 12, 24 and 36 months showed that the cumulative success rate free from isolated atrial fibrillation was 96.0%、91.0%、85.9%、79.5% and 72.7%.Conclusion:The modified off-pump biatrial mini-maze procedure is safe and effective and can be considered as an off-pump ablation option for patients and cardiac surgeons.
