Background This study presents the early and midterm outcomes of combining atrial fibrillation (AF) treatment with minimally invasive mitral valve surgery (MIMVS) at our center.

Methods From January 2017 to June 2022, our center treated a total of 86 patients with both MIMVS and surgical AF ablation. The patient cohort included 62 women (72.1%) and 24 men (27.9%). The average EuroScore II was 2.64 ± 1.49%, and the patients were followed up for an average period of 46.31 ± 9.84 months.

Results Postoperatively, 95.3% of patients experienced a change in sinus rhythm, and 86.2% were discharged in sinus rhythm. The hospital's mortality rate was 2.3%, with a late mortality rate of 3.5%. Survival analysis revealed an atrial fibrillation–free 5-year follow-up rate of 59.1 ± 9.1%. The 5-year survival rate was 92.7 ± 3.3%.

Conclusion Our 5-year experience demonstrates that the combination of MIMVS and surgical AF ablation can be routinely performed with favorable peri- and postoperative outcomes. This reflects our hospital's culture and guidance on patient selection, particularly when adopting minimally invasive approaches for multiple procedures.

背景 本研究介绍了我们中心将房颤 (AF) 治疗与微创二尖瓣手术 (MIMVS) 相结合的早期和中期结果。

方法 2017年1月至2022年6月，我中心共收治MIMVS联合手术房颤消融术患者86例。患者队列包括 62 名女性 (72.1%) 和 24 名男性 (27.9%)。 EuroScore II 平均为 2.64 ± 1.49%，患者平均随访时间为 46.31 ± 9.84 个月。

结果 术后95.3%的患者出现窦性心律改变，86.2%的患者以窦性心律出院。医院死亡率为2.3%，晚期死亡率为3.5%。生存分析显示 5 年随访无房颤率为 59.1 ± 9.1%。 5年生存率为92.7±3.3%。

结论 我们 5 年的经验表明，MIMVS 和手术 AF 消融相结合可以常规进行，并具有良好的围手术期和术后结果。这反映了我们医院对患者选择的文化和指导，特别是在采用微创方法进行多种手术时。
