Abstract:
Objective To explore the feasibility of smart-planes fetal heart ( S-planes FH ) in the display of the fetal ventricular outflow views ,and to compare diameters of fetal aorta ( AO) and pulmonary artery (PA) measured using two-dimensional echocardiography(2DE) and S-planes FH . Methods One hundred and eighty-five fetuses with gestational age of 17 - 36 weeks were enrolled . Each fetus had undergone conventional 2DE examination and the three-dimensional fetal cardiac volume datasets were obtained . The volume datasets were analyzed offline using S-planes FH . The diameters of AO and PA were measured by 2DE and S-planes FH ,respectively . Pearson correlation analysis was used to evaluate the correlation between the two methods for measuring the diameters of AO and PA . The consistency of the two methods was verified by Bland-Altman analysis . Results Fetal ventricular outflow views were successfully obtained using S-planes FH in 173 ( 93 .5％ ) cases of 185 fetuses whose ventricular outflow views were satisfactorily obtained by fetal 2DE . There were close correlations between the two methods in measuring the diameters of AO and PA ( r = 0 .84 , P = 0 .04; r = 0 .81 , P = 0 .00 ) . Bland-Altman analysis showed a close consistency between the two methods ,and their 95％ confidence intervals were ( -1 .17 ,1 .00) and ( -1 .79 ,1 .02) ,respectively . Conclusions There is a close consistency between S-planes FH and 2DE in measuring fetal AO and PA . S-planes FH may have potential for the evaluation of fetal ventricular outflow .
