Abstract
Introduction: Fetal echocardiography is the ultrasonic evaluation of the human fetal cardiovascular system
Aim: The study was conducted with the aim of evaluating the role of AV valve flow pattern in early detection of IUGR pregnancy
Material and Methods: Using Ultrasonography A comparative study of E/A value was done in normal and IUGR fetuses in different gestational age group from 15th to 37th gestational weeks. At term cases were categorized as normal and IUGR on the basis of fetal weight. Correlation of E/A value with gestational age was calculated and compared in both group to find any statistically significant difference.
Result: A positive correlation was observed between E/A value and gestational age in both groups. Low E/A values of mitral and tricuspid valves show significant correlation with low birth weight (IUGR).As ventricular stiffness decreases with advancing gestation, E/A ratio increases from 0.53 ± 0.05 in the first trimester to about 0.70 ± 0.02 in the second half of pregnancy. Indeed E/A ratios around 0.82 ± 0.04 are noted at term. The rise in E/A ratio with advancing gestation suggests a shift of blood flow from late to early diastole
Discussion: By our study, B-Mode & Spectral wave analysis of flow of Atrio-ventricular valve for early detection of IUGR with good accuracy, sensitivity, specificity, positive predictive value & negative predictive value.
Conclusion: We concluded that we can use B-Mode & Spectral wave analysis of flow of Atrio-ventricular valve for early detection of IUGR withstrong positive linear correlation with gestational age.
