Abstract:
Objective To calculate Z-score for mitral and tricuspid color blood flow widths in normal fetuses and fetuses with dilated coronary sinuses ( CS ) using fetal echocardiography ,and explore the application value of Z-score of the color flow widths of atrioventricular valves in normal fetuses and fetuses with dilated CS . Methods Two hundred and thirty-eight normal fetuses (control group) with a gestational age of 16 to 38 weeks were studied by color Doppler echocardiography . Gestational age ( GA ) ,biparietal diameter (BPD) ,femoral length (FL) ,aortic inner diameter (AOd) ,pulmonary artery diameter (PAd) ,and heart area ( HA) were measured as independent variables ,and mitral and tricuspid valve color flow widths were measured as the dependent variables . Z-score models were established by regression analysis . Thirty fetuses with dilated CS (dilated CS group) from 22 to 33 weeks'gestation were involved . The Z-score of the CS fetus was calculated based on the established Z-score models and were compared with those of the normal fetuses . Results The independent sample t-test showed that there were no significant differences in the Z-scores of the blood flow width of the fetal mitral and tricuspid valves between dilated CS group and control group ( P >0 .05) . Conclusions The simple dilated CS does not affect the mitral valve diastolic blood flow ,so there is no significant effect on the filling of left ventricular blood flow .
