Abstract:
Objective To investigate the echocardiographic features and clinical significance of prenatal diagnosis of total anomalous pulmonary venous connection (TAPVC). Methods Fetal echocardiographic images of 13 fetuses with TAPVC conifrmed by pathology or postnatal echocardiography were reviewed. Echocardiographic features and clinical signiifcance of prenatal diagnosis of TAPVC were summarized. Results Twelve fetuses with TAPVC were diagnosed prenatally by fetal echocardiography, including seven cases of supracardiac type, three cases of infracardiac type and two cases of intracardiac type. The common echocardiographic characteristics of 12 fetuses with TAPVC included slightly size discrepancy of left heart and right heart, large foramen ovale with increased shunting at the atrial level, increased distance between left atrium (LA) and descending aorta, absent insertions of pulmonary veins in the LA, presence of pulmonary venous conlfuence on the top of LA and dilatation of vessels where pulmonary venous conlfuence drained. One case was missed prenatally and intracardiac type TAPVC was diagnosed by postnatal echocardiography. Among the 13 cases, three were isolated and the other ten were all in association with other abnormalities. Conclusions There are fetal echocardiographic characteristics of TAPVC. Fetal echocardiography plays an important role in prenatal diagnosis of TAPVC.
