We describe a forme frustrée of hammock valve involving only the posterior mitral leaflet. Three adult patients were referred to surgery with the diagnosis of severe mitral regurgitation due to fibrosis of the posterior mitral leaflet. The final diagnosis was done intraoperatively. In all of them the posterior leaflet was attached to some accessory papillary muscles arranged en palisade, with three to four fused muscle heads producing restrictive leaflet motion in systole. Repair consisted in division of the papillary muscles, patch augmentation, and ring annuloplasty. This previously unreported lesion is congenital but manifests itself in adulthood.
我们描述了一种仅累及二尖瓣后叶的隐匿型吊床样瓣膜。三名成年患者因二尖瓣后叶纤维化被转诊至外科手术，诊断为严重二尖瓣反流。最终诊断在术中作出。在所有患者中，后叶附着于一些呈栅栏状排列的附属乳头肌，三到四个融合的肌头导致收缩期瓣叶运动受限。修复包括乳头肌离断、补片扩大和瓣环成形术。这种先前未报道的病变是先天性的，但在成年期表现出来。
