We present 15 patients with atrioventricular and ventriculoarterial discordance diagnosed with two-dimensional echocardiography from January 1973 to June 1991. The 15 had situs solitus and six dextrocardia. A different level of insertion of the atrioventricular valves worth from 0.77 +/- 0.3 cm, was observed in all the cases which didn't perimembranous inlet ventricular septal defect. Ten patients, presented septal insertion of one of the chords of the left atrioventricular valve, while, this insertion wasn't observed in the right atrioventricular valve. The ventricular morphology and trabeculation, permitted the identification of both ventricles in all the cases. The subxifoidea view resulted in being fundamental, for the examination of the ventriculoarterial connections. Ten cases (66.6%) had an obstruction in the pulmonary outflow tract (6 in the valve and 4 in subvalvular area) and nine (60%) ventricular septal defect (7 perimembranous and 2 muscular). We believe that the two-dimensional echocardiography gives enough information to arrive at the correct diagnosis of this cardiac malformation and of the associated anomalies. This information can be completed with the use of the color-flow Doppler.
我们呈现了1973年1月至1991年6月期间通过二维超声心动图诊断出的15例房室和心室动脉不一致的患者。这15例患者中，1例为心脏位置正常，6例为右位心。在所有无膜周部入口室间隔缺损的病例中，观察到房室瓣的插入水平不同，差值为0.77±0.3厘米。10例患者中，左房室瓣的一根腱索出现间隔插入，而右房室瓣未观察到这种插入情况。通过心室形态和小梁结构，在所有病例中均能识别出两个心室。剑突下视图对于检查心室动脉连接至关重要。10例（66.6%）患者存在肺动脉流出道梗阻（瓣膜处6例，瓣膜下区域4例），9例（60%）存在室间隔缺损（膜周部7例，肌部2例）。我们认为二维超声心动图能够提供足够的信息来正确诊断这种心脏畸形及相关异常情况。使用彩色多普勒可完善这些信息。
