Mitral regurgitation is one of the most prevalent valvulopathies with a disease burden that incurs significant healthcare costs globally. Surgical repair of the posterior mitral valve leaflet is a standard treatment, but approaches for repairing the anterior mitral valve leaflet are not widely established. Since anterior leaflet involvement is less common and more difficult to repair, fewer studies have investigated its natural history and treatment options. In this review, we discuss surgical techniques for repairing the anterior leaflet and their outcomes, including survival, reoperation, and recurrence of regurgitation. We show that most patients with mitral regurgitation from the anterior leaflet can be repaired with good outcomes if performed at centers with expertise. Additionally, equal consideration for early repair should be given to patients with mitral regurgitation from both anterior and posterior pathology. However, more studies to better evaluate the efficacy and safety of anterior mitral valve leaflet repair are needed.

前叶二尖瓣修复：我们做到了吗？

二尖瓣反流是最常见的瓣膜病之一，其疾病负担在全球范围内造成巨大的医疗费用。二尖瓣后叶的手术修复是标准治疗方法，但二尖瓣前叶的修复方法尚未广泛建立。由于前叶受累不太常见且更难以修复，因此调查其自然史和治疗方案的研究较少。在这篇综述中，我们讨论了修复前叶的手术技术及其结果，包括生存、再次手术和反流复发。我们表明，如果在具有专业知识的中心进行修复，大多数前叶二尖瓣反流的患者都可以得到良好的修复效果。此外，对于因前部和后部病理学原因导致二尖瓣反流的患者，应同等考虑早期修复。然而，需要更多的研究来更好地评估二尖瓣前叶修复的有效性和安全性。
