目的探讨超声心动图对胎儿三尖瓣下移畸形的诊断价值。方法回顾性分析5例经胎儿超声心动图检查诊断为三尖瓣下移畸形的声像图与随访结果,总结其二维及彩色多普勒血流声像图特点。结果 5例胎儿经尸解均证实为三尖瓣下移畸形。胎儿三尖瓣下移畸形的主要声像图特点表现为四腔心不对称,右心房增大,三尖瓣叶附着点下移,三尖瓣重度反流,反流起源点降低,反流面积大、反流速度低。结论超声心动图诊断胎儿三尖瓣下移畸形方法简单、可靠,对胎儿三尖瓣下移畸形的诊断具有重要的临床价值。
Objective To investigate the diagnostic value of echocardiography in fetal tricuspid regurgitation. Methods We retrospectively analyzed the sonography and follow-up results of 5 cases of tricuspid regurgitation diagnosed by fetal echocardiography, and summarized the features of two-dimensional and color Doppler flow imaging. Results 5 cases of fetal autopsy confirmed tricuspid valve deformity. Fetal tricuspid valve deformity of the main sonographic features of the performance of the four chambers cardiac asymmetry, right atrium increased, tricuspid valve attachment point down, severe tricuspid regurgitation, reflux point of origin decreased, reflux Large area, low reflux rate. Conclusion Echocardiography is a simple and reliable method for the diagnosis of fetal tricuspid regurgitation. It has important clinical value in the diagnosis of fetal tricuspid regurgitation.
