A heart specimen with double-orifice tricuspid valve is described. The tricuspid valve was divided into the anterior and posterior orifices by a bridge of leaflet tissue. The valve was stenotic because of the arcade deformity of the anterior papillary muscle to which the bridging leaflet tissue had short chordal insertions. The anterior orifice was regurgitant as a result of a deficient septal leaflet. Clinical correlation was obtained by magnetic resonance imaging of the specimen. The functional significance of the malformed valve was assessed by three-dimensional reconstruction of the two-dimensional magnetic resonance images.
描述了一个具有双孔三尖瓣的心脏标本。三尖瓣被一片小叶组织桥分为前孔和后孔。由于桥接小叶组织有短腱索附着的前乳头肌呈弓状畸形，该瓣膜存在狭窄。由于隔叶缺失，前孔存在反流。通过对标本进行磁共振成像获得了临床相关性。通过对二维磁共振图像进行三维重建评估了畸形瓣膜的功能意义。
