Abstract:
Objective To search different weeks′ gestation atrioventricular size and cardiac function change in Hb Bart′s fetal edema syndrome. Methods Color Doppler echocardiography was adopted to study 67 cases with Hb Bart′s fetal edema syndrome in different weeks′ gestation.Atrial and ventricular diameter and cardiac function were measured, and compared with those of normal fetuses in same weeks′ gestation.Results In the cases with Hb Bart′s fetal edema syndrome,the heart was enlarged from 25 weeks′ gestation,right atrial enlargement came earliest, along with gestation weeks′ followed with right ventricle,left atrium and left ventricle aggravated enlargement.From 29 weeks′ gestation left and right cardiac diastolic function was involved with complicated pericardial,pleural,peritoneal effusion the damage was clearer.During 33 weeks′ gestation,left and right heart systolic function was involved.From 25 weeks′ gestation,fetal foramen ovale began to enlarge,and the enlarged foramen was difficult to be differentiated from secondary atrial septal defect.Conclusions Echocardiography is sensitive to Hb Bart′s fetal edema syndrome,and provides reliable basis for early clinical intervention.
