Congenital mitral valve malformations are rare, but are well known and described entities. Mitral valve malformations involve mitral valve apparatuses (leaflets and annulus) and subvalvar apparatuses (chordae and papillary muscle). Case reports of accessory mitral leaflets were already described, but were usually an appendix of the normal valve. We describe here a case report and present the images of a trileaflet mitral valve sustained by three papillary muscles in a young girl with subaortic stenosis.
先天性二尖瓣畸形很少见，但却是广为人知且已有描述的病症。二尖瓣畸形涉及二尖瓣装置（瓣叶和瓣环）以及瓣下装置（腱索和乳头肌）。关于二尖瓣副瓣叶的病例报告已有描述，但通常是正常瓣膜的附属物。我们在此报告一例病例，并展示一名患有主动脉瓣下狭窄的年轻女孩中由三根乳头肌支撑的三叶二尖瓣的图像。
