Intelligence quotient IQ in congenital heart disease in Alexandria

ABSTRACT

The study comprised 2 groups of patients with congenital heart diseases [CHD]; the first included 12 patients with cyanotic CHD and the second included 32 patients with acyanotic CHD. Their ages ranged between 2 and 27 years. Intelligence quotient [IQ] was measured for all patients as regards verbal, performance and full scales. In the cyanotic group, the mean IQ for verbal, performance and full scales were lower than those in acyanotic group, but without significant statistical differences. The IQ in the lower age groups were much lower in the cyanotic group. The greater number of patients in both groups were on the borderline. Patients with Fallot's tetralogy showed lower IQ scales than the other types of cyanotic CHD. Patients with pulmonary stenosis had higher IQ scales than the other types of acyanotic CHD
