The diameters of the great arteries at their origin and also more distal are important parameters for deciding which operation technique should be performed in cyanotic congenital heart diseases. In 130 normal newborn and infants (age between 1 day and 3 years, with a weight of 2,2 through 20 kg) who were examined because of heart murmur diameters of main pulmonary artery, right pulmonary artery, left pulmonary artery, aortic root, ascending aortae, aortic arch, and isthmic region were measured echocardiographically. Then correlations between age and diameters, and weight and diameters were calculated. The mean diameter of ascending aorta grew from 0.84 cm through 1.4 cm, of main pulmonary artery from 0.75 cm through 1.4 cm, of right pulmonary artery from 0.43 cm through 0.86 cm, of left pulmonary artery from 0.42 cm through 0.88 cm, of aortic arch from 0.68 cm through 1.44 cm, and of isthmic region from 0.47 cm through 0.83 cm. The best correlation was found using linear functions between weight and diameters. The "growing-velocity" of ascending aorta was 0.043 cm/1 kg weight gain and 0.05 cm/1 kg weight gain for main pulmonary artery (0.033 cm/1 kg weight gain for right and 0.035 cm/1 kg weight gain for left pulmonary artery). The great arteries grow linearly within the first 3 years of life. The echocardiography was a reliable tool to calculate "growing-velocities".
大动脉起始处及其更远处的直径是决定对青紫型先天性心脏病采取何种手术技术的重要参数。对130例因心脏杂音而接受检查的正常新生儿和婴儿（年龄在1天至3岁之间，体重2.2至20千克）进行超声心动图检查，测量主肺动脉、右肺动脉、左肺动脉、主动脉根部、升主动脉、主动脉弓及峡部区域的直径。然后计算年龄与直径、体重与直径之间的相关性。升主动脉平均直径从0.84厘米增长至1.4厘米，主肺动脉从0.75厘米增长至1.4厘米，右肺动脉从0.43厘米增长至0.86厘米，左肺动脉从0.42厘米增长至0.88厘米，主动脉弓从0.68厘米增长至1.44厘米，峡部区域从0.47厘米增长至0.83厘米。体重与直径之间采用线性函数时相关性最佳。升主动脉的“生长速度”为每增加1千克体重增长0.043厘米，主肺动脉为每增加1千克体重增长0.05厘米（右肺动脉为每增加1千克体重增长0.033厘米，左肺动脉为每增加1千克体重增长0.035厘米）。大动脉在生命的头3年内呈线性生长。超声心动图是计算“生长速度”的可靠工具。
