title: Fetal echocardiography guidelines to predict survival of fetuses with ascites.
abstract: In a retrospective analysis of the standard protocols for fetal echocardiographic examination, 27 fetuses (mean gestational age 29 +/- 5.4 weeks) with ascites were evaluated. Fetal cardiomegaly (increased heart area/chest area ratio), the presence or absence of atrioventricular valve regurgitation, inferior vena cava and ductus venosus Doppler flow velocity and umbilical vein pulsation were evaluated quantitatively in a group of survivors and non-survivors. A statistically significant difference between the two groups was found for the presence of atrioventricular valve regurgitation (p = 0.003), and for cardiomegaly (p = 0.009). There was no statistical difference for the presence of abnormal venous flow and umbilical pulsation (p > 0.05). Abnormal venous Doppler flow velocities in the inferior vena cava and ductus venosus were observed more frequently than umbilical vein pulsation. The mean heart area/chest area ratios in the group of survivors and in the group of non-survivors were 0.34 +/- 0.09 and 0.48 +/- 0.08, respectively (p < 0.001). The mean gestational ages at the time of diagnosis of ascites in the groups of survivors and non-survivors were 33 +/- 3.3 weeks and 28 +/- 5.1 weeks, respectively (p < 0.05); the mean gestational ages at the time of delivery were 35.6 +/- 2.3 weeks and 33.3 +/- 4.9 weeks, respectively (p = 0.33). In terms of different echocardiographic features as well as the gestational age of the unborn patient with ascites, there is apparently no single indicator of a poor prognosis. Our results suggest that the prognosis is usually poor in a fetus with ascites, when cardiomegaly is detected, as well as the presence of tricuspid and mitral valve regurgitation. This is regardless of the type of venous flow and regardless of the etiology of the ascites.
