Abstract：Objective To investigate the application value of echocardiographic coronal view in diagnosis of fetal congenital cardiovascular malformation.Methods Totally 70 fetuses with congenital cardiovascular malformation,induding 51 cases of congenital vascular ring,7 cases of aorto-pulmonary septal defect and 12 cases of isolated total anomalous pulmonary venous drainage screened by echocardiography before birth in Pediatric Cardiac Center,Beijing Anzhen Hospital,Capital Medical University from January 2014 to July 2017 were retrospectively analyzed.Images of routine echocardiographic view,three vessels and trachea view and coronal view were analyzed to evaluate the diagnostic value of coronal view for different types of fetal anomalies.Results ①With combined use of coronal view,display rates of vascular ring formed by right aortic arch and the left subclavian artery in RAA accompanied by aberrant left subclavian artery were significantly increased;the discriminability between right aortic arch accompanied by left ductus arteriosus and double aortic arches was also improved;but the detectability of double aortic arches was almost the same compared with routine echocardiographic view.②Images of coronal view could clearly show the length of aorto-pulmonary septal defect and the distance between 2 groups of semilunar valves.③Imagine of coronal view could show the shape of anomalous venous arch;superimposed color Doppler could show the obstruction.Conclusion Echocardiographic coronal view can provide auxiliary and useful information for improving diagnostic accuracy of fetal congenital cardiovascular malformation.
