摘要
目的:研究多普勒超声心动图宫内诊断胎儿心脏肿瘤及合并胎儿充血性心衰(CHF)的临床意义。方法:胎儿超声心动图顺序分段法检查胎儿心脏肿瘤并评价其血流动力学改变。结果:检出心脏肿瘤12例,其中7例出现心脏肥厚扩大,2例出现胎儿水肿,表现为心胸面积比增大,心房、心室的不对称增大或心肌肥厚及心室缩短率(FS%)及心输出量(CCO)改变(P<0.001);8例中至重度二、三尖瓣反流(MR、TR),3例肺动脉瓣反流;2例出现脐静脉搏动性血流,腔静脉内径增宽及血流频谱改变。结论:应用多普勒超声心动图可清晰显示胎儿心脏肿瘤,评价与CHF的相关因素。通过主动脉和肺动脉CO的总和CCO可无创获得心输出量的指标及计算FS研究量化胎儿心功能,并可评价心内及外周血流动力学变化。
Abstract
Objective: To investigate the correlation between fetal cardiac tumor with congestive heart failure(CHF), and explore possible mechanisms of CHF. Methods: Twelve fetuses with cardiac tumor underwent echocardiographic fetal cardiac function examination. Results: ①Tumors of the heart was identified in 12 cases. ②Hydrops fetalis developed in 2 cases, with decreased ventricular fractional shortening(FS%) and combined cardiac output(CCO)(P<0.001), increased fetal cardiothoracic ratio, and asymmetrical enlargement of atrium and ventricle or myocardial hypertrophy. ③Medium to severe regurgitation of mitral valve and tricuspid valve occured in 8 cases, and regurgitation of pulmonary valve in 3 cases. Conclusion: In fetuses with cardiac tumors, Doppler echocardiography is valuable in quantifying fetal cardiac function by calculating such indices as FS and CCO, and assessing both intracardiac and peripheral hemodynamics.
