Isolated muscular ventricular septal defect was identified in 9 of 159 consecutive preterm neonates by color Doppler echocardiography, a prevalence of 56.6/1,000 live births. The neonates with ventricular septal defects appear clinically healthy, and in 87.5% of them the defect spontaneously closed within 6 to 11 months. The prevalence and rate of spontaneous closure are similar to those in full-term neonates.
在159例连续的早产新生儿中，通过彩色多普勒超声心动图发现9例孤立性肌部室间隔缺损，活产儿患病率为56.6/1000。患有室间隔缺损的新生儿临床外观健康，其中87.5%的缺损在6至11个月内自然闭合。其患病率和自然闭合率与足月儿相似。
