Study phase:

研究设计:

连续入组 

Study design:

Sequential 

研究目的:

1.主要目的:比较不同外科治疗策略对AFMR患者术后远期生存、二尖瓣反流复发及左心房逆重构的影响。 2.次要目的: (1)探究“左心房-瓣环不匹配指数对术后MR复发的预测价值。 (2)分析中度AFMR患者中,单纯房颤消融与消融联合瓣环成形术的疗效差异。 (3)探索影响术后左心房逆重构的独立危险因素。  

Objectives of Study:

1. Main objective: To compare the effects of different surgical treatment strategies on the long-term survival, recurrence of mitral regurgitation, and left atrial remodeling in AFMR patients after surgery. 2. Secondary objectives: (1) To investigate the predictive value of the "left atrium-valve annulus mismatch index" for postoperative MR recurrence. (2) To analyze the differences in efficacy between simple atrial fibrillation ablation and ablation combined with valve annulus reconstruction in patients with moderate AFMR. (3) To explore the independent risk factors influencing postoperative left atrial remodeling.

纳入标准:

1.2005年1月1日至2025年12月31日期间,在华中科技大学同济医学院附属协和医院心脏大血管外科接受二尖瓣手术的患者。 2.术前超声心动图明确诊断为功能性二尖瓣反流,且临床表现和超声特征符合房性功能性二尖瓣反流的诊断标准。 3.手术记录证实接受了二尖瓣修复手术,包括但不限于人工瓣环成形术,可同期行房颤迷宫消融术、左心耳切除术、三尖瓣成形术。 4.具有完整的医疗记录,包括术前基线资料、手术记录、至少一份术前、一份术后早期及一份远期的超声心动图报告。

Inclusion criteria

1. Patients who underwent mitral valve surgery at the Department of Cardiovascular Surgery of Tongji Hospital Affiliated to Huazhong University of Science and Technology from January 1, 2005 to December 31, 2025. 2. Preoperative echocardiography confirmed functional mitral regurgitation, and the clinical manifestations and ultrasound features met the diagnostic criteria for atrial functional mitral regurgitation. 3. The surgical records confirmed that mitral valve repair surgery was performed, including but not limited to artificial valve ring formation, and atrial fibrillation maze ablation, left atrial appendage resection, and tricuspid valve formation could be performed concurrently. 4. Complete medical records were available, including preoperative baseline data, surgical records, at least one preoperative, one early postoperative, and one long-term echocardiography report.

排除标准:

1.器质性二尖瓣病变:由风湿性心脏病、感染性心内膜炎、二尖瓣脱垂、Barlow综合征、先天性畸形等导致的瓣叶结构异常。 2.室性功能性二尖瓣反流:由缺血性心脏病、扩张型心肌病等导致的左心室扩大、收缩功能障碍或节段性室壁运动异常。 3.既往有二尖瓣手术史。 4.同期行主动脉瓣置换/修复、冠状动脉旁路移植术、心室重建术、升主动脉替换等其他主要心脏手术。 5.关键数据严重缺失,无法用于分析。

Exclusion criteria:

1. Organic mitral valve lesion: Abnormalities in the valve structure caused by rheumatic heart disease, infectious endocarditis, mitral valve prolapse, Barlow syndrome, congenital malformations, etc. 2. Ventricular functional mitral regurgitation: Left ventricular enlargement, systolic dysfunction or segmental ventricular wall motion abnormalities caused by ischemic heart disease, dilated cardiomyopathy, etc. 3. Previous history of mitral valve surgery. 4. Concurrently undergoing other major cardiac surgeries such as aortic valve replacement/repair, coronary artery bypass grafting, ventricular reconstruction, ascending aorta replacement, etc. 5. Critical data is severely lacking and cannot be used for analysis.
