During obstetrical ultrasound examinations, 200 M-mode and 35 real-time two-dimensional echocardiographic studies were performed on 180 fetuses of high-risk pregnancies. Fetal gestational ages ranged from 18 to 41 weeks. M-mode "sweeps" demonstrating mitral- and septal-aortic fibrous continuity were obtained in 115 studies. Paradoxic septal motion in 50 fetuses suggested relarive right ventricular volume loading. Congenital cardiac malformations were accurately diagnosed in a 34-week fetus with pulmonary atresia and hypoplastic right ventricle and in a 28-week fetus with a univentricular heart. Congenital complete atrioventricular block was diagnosed in a 28-week fetus and atrial flutter with variable atrioventricular block was diagnosed in a 38-week fetus. The use of echocardiographic studies to evaluate cardiac structure and rhythm in utero assists in counseling prospective parents and in planning postnatal management for their offspring.
在产科超声检查中，对180例高危妊娠胎儿进行了200次M型和35次实时二维超声心动图研究。胎儿孕周为18至41周。在115项研究中获得了显示二尖瓣和室间隔 - 主动脉纤维连续性的M型“扫描”图像。50例胎儿出现矛盾性室间隔运动，提示相对右心室容量负荷增加。在一名34周龄患有肺动脉闭锁和右心室发育不全的胎儿以及一名28周龄患有单心室心脏的胎儿中准确诊断出先天性心脏畸形。在一名28周龄胎儿中诊断出先天性完全性房室传导阻滞，在一名38周龄胎儿中诊断出伴有可变房室传导阻滞的心房扑动。使用超声心动图研究评估子宫内的心脏结构和节律有助于为准父母提供咨询，并为其后代规划产后管理。
