A case of double mitral valve orifice associated with atrioventricular canal was found at operation. These two anomalies are frequently associated. Double mitral valve is usually subclinical and does not necessarily need to be corrected, depending on the associated anomalies, the extent of the defect, and the personal experience of the surgeon. The embryology of double mitral valve is complicated and still needs to be clarified.
手术中发现一例双二尖瓣口合并房室管畸形的病例。这两种畸形常合并存在。双二尖瓣通常为亚临床型，是否需要纠正不一定，这取决于合并的畸形、缺损程度以及外科医生的个人经验。双二尖瓣的胚胎学很复杂，仍有待阐明。
