Isolated posterior mitral valve cleft (MVC) is a rare congenital anomaly that can be easily overlooked with standard 2-dimensional imaging.
A 94-year-old woman with progressive heart failure symptoms was found to have severe mitral regurgitation due to an isolated posterior MVC. Three-dimensional echocardiography provided detailed visualization of the lesion's anatomy and confirmed the diagnosis. After excluding a percutaneous repair due to the cleft's complexity, she underwent minimally invasive surgical repair, resulting in substantial symptomatic improvement.
Posterior MVCs are infrequently reported and often missed by conventional imaging. Advances in 3-dimensional echocardiography have enhanced diagnostic accuracy, guiding targeted interventions. This case shows the importance of comprehensive imaging for such rare anomalies and the feasibility of surgical repair, even in elderly patients.
孤立性二尖瓣后叶裂（MVC）是一种罕见的先天性异常，在标准二维成像中很容易被忽视。
一名94岁有进行性心力衰竭症状的女性被发现因孤立性二尖瓣后叶裂导致严重二尖瓣反流。三维超声心动图提供了病变解剖结构的详细可视化并确诊。由于裂的复杂性排除经皮修复后，她接受了微创外科修复，症状得到显著改善。
二尖瓣后叶裂报道较少，常被传统成像漏诊。三维超声心动图的进展提高了诊断准确性，指导靶向干预。本病例显示了对于此类罕见异常进行全面成像的重要性以及外科修复的可行性，即使是老年患者。
