Objective We aimed to evaluate fetal left modified myocardial performance index and renal artery Doppler parameter in fetuses with isolated oligohydramnios and normal amount of amniotic fluid. Material and methods In a prospective cohort study, 25 pregnancies with isolated oligohydramnios and 25 healthy gestational age matched controls between 24+0 to 36+6 weeks of gestation were recruited. Primary outcome was to compare left modified myocardial performance index and mean fetal renal artery PI and secondary outcome was to compare adverse perinatal outcomes between the groups. Results Mean modified myocardial performance index was significantly higher and isovolumetric relaxation time was longer in the isolated oligohydramnios group (p=0.001, p=0.009). Mean renal artery PI values were not different between the groups. Birthweight and gestational age at birth were significantly lower (p=0.041, p=0.001), and incidences of delivery before 37 weeks and Cesarean section due to non-reassuring fetal heart rate testing were significantly higher (p=0.034, p=0.021) in women with isolated oligohydramnios than the control group. We found no significant relationship between modified myocardial performance index and adverse perinatal outcomes. Conclusion Fetuses with isolated oligohydramnios have increased left modified myocardial performance index which may be due to mild cardiac diastolic dysfunction. Increased modified myocardial performance index is not associated with adverse perinatal outcomes and does not seem to help in the management of pregnancies before 37 weeks of gestation with isolated oligohydramnios.
