title: Cardiac function monitoring of fetuses with growth restriction.
abstract: OBJECTIVE
  To describe the time sequence of changes in cardiac function in intrauterine growth restriction.
  
  
  METHODS
  This was a prospective longitudinal study on 22 singleton pregnancies with growth-restricted fetuses. Pulsatility indices of fetal arterial and venous Doppler waveforms, systolic peak velocity in the aorta and pulmonary artery, right and left ventricular shortening fraction and atrioventricular flow E/A ratio were assessed at each monitoring session. Logistic regression was used for modeling the probability of abnormality of a variable in relation to the time interval before delivery. Trends over time were analyzed by Mann-Withney U-test.
  
  
  RESULTS
  Umbilical artery pulsatility index was the first variable to become abnormal, followed by the middle cerebral artery, right diastolic indices (right E/A, ductus venosus), right systolic indices and, finally, both diastolic and systolic left cardiac indices.
  
  
  CONCLUSIONS
  We have found an earlier and more pronounced right than left and diastolic than systolic fetal cardiac function deterioration in growth restricted fetuses monitored longitudinally.
