The largest group of CHD was ventricular septal defect, 24.0%, followed by persistent ductus arteriosus, 12.6%; atrial septal defect, 9.2%; coarctation of the aorta, 7.0%; pulmonary stenosis, 6.0%; and tetralogy of Fallot, 5.8%. The cumulated lethality for all 5249 children ws 25% at 1 month, 42% after 5 years, and 48% at the age of 15 years. CHD was found in 135 cases among 5835 siblings (2.3%).
