We describe a rare case of double-orifice mitral valve discovered with echocardiography. The tensor apparatus composed of four papillary muscles and anomalous attachment of chordae tendineae represents the main findings. Two supernumerary muscles in combination with the altered chordal insertion on the central portion of the anterior mitral leaflet are responsible for the V-shaped ("seagull wing") and spectacle-like features of the mitral valve in the short-axis view. These altogether allow precise identification of this congenital malformation.
我们描述了一例通过超声心动图发现的双孔二尖瓣罕见病例。由四个乳头肌和异常腱索附着组成的腱索装置是主要发现。两根额外的肌肉与二尖瓣前叶中央部分腱索插入的改变相结合，导致二尖瓣在短轴视图中呈现V形（“海鸥翼”）和眼镜样特征。这些共同使得能够精确识别这种先天性畸形。
