摘要

小叶组织的缺乏和收缩运动受限仍然是二尖瓣修复的挑战。除了功能性或继发性二尖瓣反流外,心房功能性二尖瓣反流以慢性心房颤动、左心室功能保留和房源性小叶栓系为特征,加剧了小叶稀缺,使二尖瓣修复复杂化。为了解决这个问题,我们介绍了“肘关节补片修复”,这是一种使用自体心包覆盖补片加强二尖瓣后叶的新技术。一例65岁男性慢性心房纤颤合并严重二尖瓣反流,符合心房功能性二尖瓣反流的患者行“肘关节补片修复”联合环成形术和新脊索置入术。该入路有效地处理了后二尖瓣小叶缺损,恢复了配合面。“肘部补片”是解决心房功能性二尖瓣反流和部分卡彭迪埃ⅲ类病例小叶不足的一种简单有效的方法。需要进一步的研究来评估其长期耐久性。

Posterior Leaflet Overlay Patch Reinforcement for Mitral Valve Posterior Tethering: The Elbow Patch Repair.

The scarcity of leaflet tissue and restricted systolic motion remain challenges in mitral valve repair. In addition to functional or secondary mitral regurgitation, atrial functional mitral regurgitation, characterized by chronic atrial fibrillation, preserved left ventricular function, and atriogenic leaflet tethering, exacerbates leaflet scarcity, complicating mitral valve repair. To address this, we introduce the "elbow patch repair," a novel technique using an autologous pericardium overlay patch to reinforce the posterior mitral valve leaflet. A 65-year-old male patient with chronic atrial fibrillation and severe mitral regurgitation consistent with atrial functional mitral regurgitation underwent the "elbow patch repair" combined with annuloplasty and neochordae placement. This approach effectively managed posterior mitral valve leaflet deficiency and restored the coaptation surface. The "elbow patch repair" offers a straightforward and effective solution for leaflet shortage in atrial functional mitral regurgitation and select cases of Carpentier Class IIIb. Further studies are needed to assess its long-term durability.
