Complex Congenital Heart Disease and Neurodevelopment. A Case Study of Fraternal Twins.

Congenital heart defects have been associated with adverse neurodevelopmental outcomes due to factors that result in a hypoxic-ischemic cerebral cumulative effect. We present a pair of fraternal twins: the first twin was healthy, and the second was born with a complex congenital heart defect (CCHD). They were followed for growth and neurodevelopmental outcomes to determine the comparative effect of exposure to a CCHD. Results show that exposure to a CCHD could be related to a persistent motor deficiency with hypotonia and concurrent height for age delay. CCHD requires a comprehensive neurodevelopmental approach; the pathophysiology and the surrounding stimuli are influential.
