We present a case study of a patient with a congenital heart block associated with a left isomerism that was diagnosed during the 26th week of gestation. The mother had type 2 diabetes mellitus that was difficult to control during the early stages of the pregnancy. A fetal echocardiogram revealed an atrioventricular dissociation, with an atrial rate of 120 bpm and a ventricular rate of 55 bpm. Subsequent examinations also revealed a left isomerism in the fetus. To increase the fetal heart rate, a continuous intravenous infusion of ritodrine was administered. The fetal ventricular rate rapidly increased to 65 bpm. The pregnancy successfully continued until term and a female infant weighing 3,182 g was born via a cesarean section. A subsequent surgery was performed to provide the infant with a permanent cardiac pacemaker, and notably, the child is now 4 months of age and her growth has been within the normal range.
我们呈现了一例 26 孕周时诊断的先天性心脏传导阻滞伴左位异构的病例。母亲患有 2 型糖尿病，在妊娠早期难以控制。胎儿超声心动图显示房室分离，心房率为 120 次/分，心室率为 55 次/分。随后的检查还显示胎儿存在左位异构。为了提高胎儿心率，给予了利托君持续静脉滴注。胎儿心室率迅速增加至 65 次/分。妊娠成功继续至足月，通过剖宫产娩出一名 3182 克重的女婴。随后进行了手术为婴儿提供永久性心脏起搏器，值得注意的是，该患儿现在已经 4 个月大，生长发育处于正常范围内。
