Subcostal oblique 2-dimensional echocardiography was performed in 64 infants younger than 2 years with complete transposition of the great arteries (TGA) (situs solitus, concordant atrioventricular and discordant ventriculoarterial connections). All patients examined before cardiac catheterization had a correct diagnosis by 2-dimensional echocardiography using the subcostal oblique views. Twelve patients had associated left ventricular (LV) outflow tract obstruction and 7 had right ventricular (RV) outflow obstruction. The standard parasternal views failed to diagnose obstruction in 1 patients with LV outflow obstruction and 5 with RV outflow obstruction; the subcostal left oblique cut and long axis of the left ventricle visualized all left-sided obstructions, and right-sided obstructions were correctly displayed in 5 of 7 cases using a combination of left oblique and right oblique cuts. Two-dimensional echocardiographic subcostal oblique views allow an excellent definition of the morphologic characteristics of RV and LV outflow tracts in patients with TGA and improve the diagnosis of the outflow obstruction in these malformations.
对64例2岁以下患有完全性大动脉转位（TGA）（心房正位、房室一致但心室动脉连接不一致）的婴儿进行了肋下斜位二维超声心动图检查。所有在心脏导管检查前接受检查的患者，通过使用肋下斜位视图的二维超声心动图均得到了正确诊断。12例患者伴有左心室（LV）流出道梗阻，7例伴有右心室（RV）流出道梗阻。标准胸骨旁视图未能诊断出1例左心室流出道梗阻患者和5例右心室流出道梗阻患者的梗阻情况；肋下左斜切面和左心室长轴显示了所有左侧梗阻情况，并且通过左斜切面和右斜切面的组合，7例右侧梗阻中有5例得到了正确显示。二维超声心动图肋下斜位视图能够很好地明确TGA患者右心室和左心室流出道的形态特征，并改善对这些畸形中流出道梗阻的诊断。
