Neonates with a pansystolic murmur who had Doppler echocardiography were reviewed. Ten infants had tricuspid regurgitation (detected at a mean age of 25 hours), 12 had a ventricular septal defect (detected at 65 hours), and seven had both. Tricuspid regurgitation is the more likely cause of a pansystolic murmur at the lower left sternal border in the first day of life.
对患有全收缩期杂音且接受了多普勒超声心动图检查的新生儿进行了回顾性研究。10例婴儿患有三尖瓣反流(平均在25小时时被检测到),12例患有室间隔缺损(在65小时时被检测到),7例同时患有这两种疾病。三尖瓣反流更有可能是出生后第一天左下胸骨缘全收缩期杂音的病因。
