Cognitive development in transposition of the great vessels.

Abstract

Ten children who had had transposition of the great vessels (TGV) repaired, deep hypothermia, and cardiac arrest were examined. Seven children with acyanotic heart disease and 12 unaffected siblings were tested for comparison. Their intelligence, academic achievement, and behaviour was studied. The group with TGV had lower performance subscores on the intelligence test, an increase in somatic complaints, and aggressive behaviour.
