Abstract
Congenital defects are frequent, occurring in 2-3% of live births, with high morbidity and mortality. Congenital heart defects are the most frequent, occurring in 1% of all live births. Most occur as isolated malformations, but approximately 1/3 are part of a syndrome, usually of genetic etiology. The correct etiological diagnosis is important for useful clinical follow-up and genetic counseling. Children born with congenital heart defects should be carefully examined for other malformations and dysmorphia.
