Abstract

Normal aortic root dimensions are established using 334 sequential echocardiograms in 111 average-gestational-age premature infants between 600-2500 g. The aortic roots increased in diameter from 0.53 cm +/- 0.04 cm for infants weighing 600-900 g to 0.80 +/- 0.08 cm for infants weighing between 2200-2500 g.

摘要

通过对111名平均胎龄的早产婴儿（体重600 - 2500克）的334份连续超声心动图来确定正常主动脉根部尺寸。主动脉根部直径从体重600 - 900克婴儿的0.53厘米±0.04厘米增加到体重2200 - 2500克婴儿的0.80±0.08厘米。
