Functional tricuspid valve regurgitation due to left sided valve lesions remains a common finding. Nowadays, different types of three-dimensional rings and flexible bands are considered to be the gold standard techniques for repair of such functional regurgitation. Our study aimed for long-term comparison of the durability and effectiveness of those techniques. The data of 170 adult patients with moderate or more functional tricuspid regurgitation secondary to mitral stenosis or regurgitation receiving tricuspid valve repair using either rigid 3D rings (contour 3D or MC3 ring) or prosthetic fashioned bands (Dacron or PTFE) and mitral valve surgery between March 2013 and September 2018 were collected and analysed. Patients were classified in two matched groups: ring group (group A) consisting of 90 cases and band group (group B) consisting of 80 cases. follow-up period ranged from 55.2 to 78 months (mean 67.2 ± 10.8), during this period New York heart association for dyspnea functional class evaluation and full echocardiographic assessment were done and was scheduled as following: before hospital discharge, after 6 months of surgery and finally, every 2 years. In-hospital mortality was 1(1.1%) and 2 (2.5%) with p value 0.49 after ring or band annuloplasty, respectively. No significant differences in both groups regarding hospital mortality and morbidities. There was statistically significant decrease in NYHA class, degree of TR, and PASP within the 2 groups postoperatively with p value of 0.03, 0.04, and 0.033, respectively, with no statistically significant difference between both groups (p value > 0.05). There was statistically significant difference in the freedom from recurrent TR and need for reoperation during the follow-up period between both groups with lower recurrence and reoperation rates in group A, (p value 0.03 and 0.001, respectively). Tricuspid valve repair with different annuloplasty rigid three dimensional rings or fashioned flexible bands for functional tricuspid regurgitation offers good long-term outcome. Yet, the rigid rings maintain their benefits on the rate of recurrent TR and the need for reoperation.

三尖瓣三维环与传统的柔性带瓣环成形术治疗功能性三尖瓣反流：长期比较研究

由于左侧瓣膜病变引起的功能性三尖瓣关闭不全仍然是常见的发现。如今，不同类型的三维环和柔性带被认为是修复这种功能性反流的金标准技术。我们的研究旨在对这些技术的持久性和有效性进行长期比较。三月之间在170例二尖瓣狭窄或反流继发中度或以上功能性三尖瓣反流的成年患者中，使用刚性3D环（轮廓3D或MC3环）或假体成形带（Dacron或PTFE）接受三尖瓣修复和二尖瓣手术的数据收集并分析了2013年和2018年9月。将患者分为两个匹配的组：环组（A组）为90例，乐队组（B组）为80例。随访时间为55.2至78个月（平均67.2±10.8），在此期间，纽约心脏协会进行了呼吸困难功能等级评估和全面的超声心动图评估，其安排如下：出院前，手术后6个月最后，每两年一次。环或带瓣环成形术后的院内死亡率分别为1（1.1％）和2（2.5％），p值为0.49。两组在医院死亡率和发病率方面无显着差异。两组术后NYHA分级，TR和PASP程度均有统计学意义的降低，p值分别为0.03、0.04和0.033，两组之间无统计学差异（p值> 0.05）。两组之间的随访期间，复发TR的自由度和需要再次手术的差异均有统计学意义，A组的复发率和再次手术率较低（分别为p值0.03和0.001）。三尖瓣瓣膜修复具有不同的瓣环成形术刚性的三维环或用于功能性三尖瓣关闭不全的老式柔性带，可提供良好的长期效果。但是，刚性环在TR复发率和再次手术的需要上仍能保持其优势。三尖瓣瓣膜修复具有不同的瓣环成形术刚性三维环或用于功能性三尖瓣关闭不全的可弯曲带，可提供良好的长期效果。但是，刚性环在TR的复发率和再次手术的需要上仍能保持其优势。三尖瓣瓣膜修复具有不同的瓣环成形术刚性三维环或用于功能性三尖瓣关闭不全的可弯曲带，可提供良好的长期效果。但是，刚性环在TR的复发率和再次手术的需要上仍能保持其优势。
