Maternal hemodynamic adaptation in the first weeks of pregnancy is defective in IUGR pregnancies, presumably associated with a concomitant inadequacy of the vascular filling state.

The Ross procedure for congenital aortic valve disease in children and young adults offers excellent hemodynamics, with the added advantage of real potential for growth. It should be considered the treatment of choice in this age group.

Fetal growth restriction is preceded by defective volume adaptation very early in pregnancy. It appears that the maternal compensation mechanisms are unable to resolve the transient state of vascular underfill seen in this period in normal gestation.
