心房功能性二尖瓣反流(AFMR)是由心房颤动和左房增大引起的。本研究旨在评价左房折叠术(LAP)治疗AFMR的疗效。本院2000年1月至2019年5月共收治二尖瓣手术患者1164例，其中22例行二尖瓣反流手术。根据是否行LAP分为两组(LAP + 组，n = 9例；LAP − 组，n = 13例)。术前、术后CT测量二尖瓣角度(MV角)(二尖瓣水平倾斜度)。排除二尖瓣反流、 <； 左心室射血分数55%、左室舒张内径 >； 男性60 mm、女性 >； 55 mm、主动脉瓣病变、二尖瓣钙化、肥厚型梗阻性心肌病、“重做”和急诊病例。行二尖瓣置换术6例，二尖瓣环成形术16例。随访期内无二尖瓣返流复发或瓣膜结构恶化。无住院死亡；在随访期内发生3例死亡。与LAP − 组相比，LAP + 组的MV角(16.6 ± 8.1°vs.1.2 ± 6.9°，p <； 0.01)和左房内径(18.4 ± 7.0 mm vs.6.9 ± 14.6 mm，p = 0.02)显著减小。AFMR手术效果满意。LAP可能适合于纠正二尖瓣水平倾斜的角度。未来需要考虑更多的案例。
Atrial functional mitral regurgitation (AFMR) is caused by atrial fibrillation and left atrial enlargement. Our study aimed to evaluate the efficacy of left atrial plication (LAP) for AFMR. Of 1164 mitral valve surgery patients at our hospital from January 2000 to May 2019, 22 patients underwent surgery for AFMR. Our retrospective analysis divided the patients with AFMR into two groups according to whether LAP was performed (LAP + group, n = 9; LAP − group, n = 13). Mitral valve angle (MV angle) (horizontal inclination of mitral valve) was measured by pre- and post-operative computed tomography scan. Individuals with type II mitral regurgitation, left ventricular ejection fraction of < 55%, males with left ventricular endo-diastolic dimension of > 60 mm and females with > 55 mm, aortic valve disease, mitral valve calcification, hypertrophic obstructive cardiomyopathy, and both “redo” and emergency cases were excluded. Mitral valve replacement was performed in 6 patients and mitral ring annuloplasty in 16 cases. No recurrence of mitral regurgitation or structural valve deterioration occurred during the follow-up period. There were no hospital deaths; 3 deaths occurred during the follow-up period. Compared to the LAP − group, the LAP + group demonstrated a significantly greater decrease of MV angle (16.6 ± 8.1° vs. 1.2 ± 6.9°, p < 0.01) and left atrial dimension (18.4 ± 7.0 mm vs. 6.9 ± 14.6 mm, p = 0.02). Surgical results of AFMR were satisfactory. LAP may be appropriate for correcting the angle of a mitral valve tilted horizontally. More cases need to be considered in the future.
