Outline of Final Research Achievements

We investigated congenital heart diseases in children with chromosome abnormalities. Our research is based on medical charts from five hospitals and two questionnaire surveys of the patients’ parents. The total number of patients with Down syndrome in the present research was 1310, with 626 females and 684 males. The rate of complication of congenital heart diseases in females (354; 57%) was higher than that in males (338; 49%) significantly (p=0.010). Moreover, females had significantly more medical operations related to heart diseases (199; 32%) than males (175; 26%) (p=0.018). Those heart diseases were VSD, ASD, AVSD, PDA and TOF, in the order of appearance frequency. PDA was found in more females than males.
