Ten patients with double orifice mitral valve and atrioventricular septal defect (AVSD) were examined. There were four cases with incomplete type, three with intermediate type and three with complete type AVSD. All patients with incomplete type AVSD were doing well after the mitral cleft repair, Leaving the accessory orifice untouched. Various valve repair procedures and prosthetic valve replacement were performed in the patients with intermediate and complete types of AVSD with left-sided atrioventricular valve regurgitation. There were three operative deaths, which included one patient with the intermediate type and two with the complete type. All of them were one-month old babies and were operated on emergency. Their general operative findings were hypoplasia of the common atrioventricular valve leaflets, abnormal attachment of the chorda tendineae and papillary muscle dysplasia. These findings increased the difficulty of the valve plasty to control mitral regurgitation.
对10例双孔二尖瓣合并房室间隔缺损（AVSD）的患者进行了检查。其中4例为不完全型，3例为中间型，3例为完全型AVSD。所有不完全型AVSD患者在二尖瓣裂修复术后情况良好，未处理副孔。对合并左侧房室瓣反流的中间型和完全型AVSD患者进行了各种瓣膜修复手术和人工瓣膜置换。有3例手术死亡，其中1例为中间型，2例为完全型。他们均为1个月大的婴儿，接受了急诊手术。其一般手术所见为共同房室瓣叶发育不全、腱索附着异常和乳头肌发育异常。这些发现增加了瓣膜成形术控制二尖瓣反流的难度。
