Functionally uni-leaflet mitral valves are extremely rare. In severe cases, they are considered incompatible with life beyond the neonatal period. We present a case series of three adults with almost complete absence of the posterior mitral valve leaflet and who are asymptomatic, with no more than mild mitral regurgitation. We believe that this is the first reported instance of such findings in a single family.
功能性单叶二尖瓣极为罕见。在严重情况下，人们认为这类情况在新生儿期之后无法存活。我们报告了一个病例系列，三名成年患者几乎完全缺失二尖瓣后叶，且无症状，仅有轻度二尖瓣反流。我们认为这是首次报道在一个家族中出现此类情况。
