The Research Of Color Doppler Echocardiography Diagnosis Of Fetal Congenital Heart Disease

Objective: Application of color doppler echocardiography in prenatal to fetalheart for inspection,to evaluate the application value of the diagnosis of fetal prenatalultrasonographic in screening congenital heart disease,and analyzes fetal ultrasoundscreening congenital heart disease risk factors. Methods: Hearts of6129fetus(including2022cases with the screening of the risk factors) were inspected byseven-views order section method [On the transverse abdominal-the4-chamberview-left, right ventricular outflow the edge(the crossed-relation of aorta andpulmonary artery view)-three-vessel-trachea view of the aorta-cut-ductus bow on cutsurface-inferior vena cava cut surface] fetus with congenial heart disease wereautopsied after induced labor and were contrast with the results of the follow-up afterbirth, and the screening11risk factors were analyzed, Ultrasound screening out of101patients with congenital heart disease have20an example fetus umbilical cordblood or amniotic fluid of chromosomes inspection. Results:101cases (including64cases with a screening of the risk factors) of fetal congenital heart structuredexception (dysrhythmias not including) be ultrasound screening out,100cases werefollowed up,2cases with asds misdiagnosed, in11screening high risk factors of the10screening fetal congenital heart disease were the independent risk factors, in8cases of chromosome abnormality, with18-3body more see. Conclusion:Echocardiography diagnosis of fetal congenital heart disease (especially the screeningof risk factors for fetus) is more accurate and safety of the imaging methods, andprovide the basis for the chromosome check.
