Abstract Objective: To study and analyze the clinical value of prenatal ultrasound diagnosis in fetal cardiovascular malformations. Methods: 1 000 cases of pregnant women from January 2014 to January 2017 in the First Central Hospital of Baoding were selected as the research objects, the prenatal ultrasound examination was implemented, the test results were analyzed, and the results were compared with postnatal autopsy or postpartum ultrasound examination results. Results: 57 cases of fetal cardiovascular malformations were found through prenatal fetal echocardiographic examination in 1 000 cases of pregnant women, and the malformation rate was 5.7%(57/1 000). There were 36 cases diagnosed by cardiovascular ultrasound after delivery, 11 cases confirmed by autopsy after induction of labor, and 10 cases lost to follow-up, the accuracy rate of prenatal ultrasonography was 82.46%(47/57). 2 cases of ductus arteriosus tortuosity and stenosis were re-examined after 1 month of delivery, and the results were normal; 2 cases of ventricular septal defect wereclosed after 4 months of delivery. 943 cases of maternal prenatal fetal echocardiographic examination showed no abnormalities, including 4 cases diagnosed with ventricular septal defect or atrial septal defect by echocardiography after birth; advanced age and ectopic pregnancy are high risk factors for cardiovascular malformations of the fetus. Prenatal ultrasound examination in early pregnancy and reexamination in late pregnancy are appropriate timing for ultrasound examination. Conclusion: Prenatal ultrasonography can effectively improve the quality of maternal delivery and improve the quality of life of newborns, which has important clinical value.
