Longitudinal hemodynamic evaluation of uncomplicated twin pregnancies according to chorionicity: physiological cardiovascular dysfunction in monochorionic twin pregnancy

CONCLUSIONS: Maternal cardiovascular function undergoes significant changes during an uncomplicated twin pregnancy and chorionicity influences maternal hemodynamics. In both twin pregnancies the hemodynamic changes are detected as early as the first trimester. In DC twin pregnancies the maternal hemodynamics remain stable during the rest of pregnancy. On the contrary, in MC twin pregnancies the rise in maternal CO continues in the second trimester to sustain the higher placental growth. There is a subsequent cross-over with a reduction in cardiovascular performance during the third trimester. This article is protected by copyright.
