Incidence of congenital heart disease in Qatari children.

We surveyed the incidence of congenital heart disease in 49887 native live born children in the period between 1984 to 1994 in Qatar. Each child with clinically suspected congenital heart disease underwent echocardiographic examination. Magnetic resonance imaging, cardiac catheterization and surgical intervention were done at the discretion of the patient's pediatric cardiologist.
