Abstract:
Objective To investigate the clinical application valve of prenatal ultrasound in diagnosis of fetal isolated levocardia ( IL ) . Methods Thirty-eight IL fetuses diagnosed in three prenatal diagnosis centers from 2000 to 2016 were reviewed with their prenatal ultrasound features and cardiac and extracardiac malformations . Results Thirty-eight IL cases included 19 cases of left isomerism ( LI) ,14 cases of right isomerism( RI) and 5 non-classified cases . The overall incidence of malformations in IL patients was 97 .4％with 94 .7％ in LI patients and 100％ in RI patients . The incidence of cardiac malformations was 92 .1％with 84 .2％ in LI patients and 100％ in RI patients . The most common congenital heart diseases were:right ventricle outlet obstruction , univentricular physiology and atrioventricular septal defect . Anomalous pulmonary venous connection was more commonly seen in LI patients than in RI patients . The most common extracardiac malformation was duodenal obstruction( 86 .9％ ) . Inferior vena cava interruption and polysplenia were more commonly seen in LI patients .Juxtaposition of aorta and inferior vena cava and asplenia were more commonly seen in RI patients . Conclusions IL is very rarely seen in population with high incidence of congenital heart diseases and extracardiac malformations .
