严重的围产期危急状态,特别是窒息和低血糖能引起新生儿一过性的心脏功能不良。这些婴儿表现的特点为心脏扩大、一过性杂音、青紫并常有充血性心力衰竭。作者在某新生儿重症医护中心观察了14名有明显围产期危急状态的足月婴儿,他们都有一过性心肌功能不良伴以三尖瓣闭锁不全。以前,除有个别报导外,这些发现并未被识别。材料和方法近年来,在Florida大学,对5名有明显三尖瓣闭锁不全的新生儿进行了心导管检查(第1组),另9名婴儿是按临床观察诊断为一过性三尖瓣闭锁不全的(第Ⅱ组)。
Severe perinatal crisis, especially asphyxia and hypoglycemia can cause neonatal transient cardiac dysfunction. These infants are characterized by enlarged heart, transient murmur, bruising and often congestive heart failure. The authors examined 14 full-term infants with a significant perinatal crisis in a neonatal intensive care center who had transient myocardial dysfunction with tricuspid regurgitation. In the past, these findings have not been identified except for individual reports. Materials and Methods In recent years, at the University of Florida, 5 neonates with obvious tricuspid regurgitation had a cardiac catheterization (group 1) and 9 others had been clinically diagnosed as transient tricuspid Incomplete (Group II).
