Three adult patients with a double-orifice left atrioventricular valve (AV) were studied by both precordial and transesophageal ultrasound imaging, (two transverse plane and one biplane studies) to compare and contrast the information obtained by either imaging modality. In two patients, this pathologic condition was associated with other congenital heart malformations--a muscular inlet ventricular septal defect in the first, atrioventricular and ventriculoarterial discordance and an unrestrictive ventricular septal defect in the second. In the third patient, the double-orifice left AV valve existed as an isolated lesion. In the first and second case, both orifices were of similar size; in the third the additional orifice was of diminutive size and was demonstrated only by transesophageal longitudinal plane scanning. In summary, in this adult patient group, transesophageal echocardiography with color flow mapping was superior to precordial scanning in the assessment of both the morphology and functional status of a double-orifice left AV.
对三名患有双孔型左房室瓣（AV）的成年患者进行了胸前区和经食管超声成像研究（两项横断面研究和一项双平面研究），以比较和对比两种成像方式所获得的信息。在两名患者中，这种病理状况与其他先天性心脏畸形相关——第一名患者伴有肌部流入道室间隔缺损，房室和心室动脉不一致，第二名患者伴有非限制性室间隔缺损。在第三名患者中，双孔型左房室瓣为孤立性病变。在第一例和第二例中，两个瓣口大小相似；在第三例中，额外的瓣口尺寸较小，仅通过经食管纵向平面扫描才能显示。总之，在这个成年患者组中，经食管超声心动图彩色血流成像在评估双孔型左房室瓣的形态和功能状态方面优于胸前区扫描。
