Abstract Objective: To discuss the value of echocardiography in diagnosis of premature closure and constriction of fetal ductus arteriosus, and to observe the prognosis. Methods: Analyzing the echocardiography features in 1 case of premature closure of fetal ductus arteriosus and 6 cases of constriction of fetal ductus arteriosus, observing the prognosis of all 7 cases. Results: The main echocardiography features of premature closure and constriction of fetal ductus arteriosus were truncation or narrowing of the lumen, accelerated systolic and diastolic blood flow in ductus arteriosus, tricuspid regurgitation, dilation of right heart, broadening of main pulmonary artery and increased pulmonary artery pressure. The prognosis was favorable if the treatment was appropriate. Conclusion: Echocardiography plays an important role in diagnosis of premature closure and constriction of fetal ductus arteriosus.
