Objectives Right atrium and left atrium of the fetal heart play a fundamental role in fetal heart circulatory physiology. Methods Excursion of fetal atria walls and tracings of foramen ovale (FO) flap movement were analyzed by M-mode echocardiography by new FO index to determine fetal and neonatal outcome in the first week and month of life in various congenital heart defects. The study group was divided into 3 subgroups: group A: neonates stable after birth (all on I.V. prostaglandin infusion) for at least 7 days, group B: neonates unstable after birth (despite I.V. prostaglandin infusion) requiring catheterization procedure or early cardiac surgery in utero demise. Results The average values of FO index: group A – 32, group B – 20, group C – 12.Schaffe test showed statistical difference of FO index between group A and B (p=0.029) and group A and C (p=0.001), but no difference between group B and C (p=0.24) The FO index of stability was determined by ROC curve analysis. Cut-off point distinguishing between postnatal stability and postnatal instability + in utero demise constituted FO index=25 (specificity 82%; sensitivity 90%). Conclusions Prenatal features of atrial M-mode echocardiography shortly before birth might be helpful to predict the short term prognosis of fetal hemodynamic stability or instability shortly after birth regardless of the type of congenital heart defects (CHD). |
