Prevalence, treatment, and outcome of heart disease in live-born children: A prospective analysis of 91,823 live-born children

1989 
All 91,823 children born in 1980 in Bohemia (population 6.314 million; area 52,478 square kilometers) were examined at least four times during infancy and at the age of three and four years. All children who died were autopsied and those with heart disease were selected. A total of 779 children (8.223/1000 live births) were suspected by provincial pediatric cardiologists of having a heart disease. All of these were examined at the age of four years at our Center of Pediatric Cardiology. At this age heart disease was proved in 613 alive or decreased children (6.676/1000 live births), congenital cardiac malformations in 589 (6.415/1000 live births), and cardiomyopathies in 24. The most frequent congenital heart defects (CHD) were ventricular septal defect (VSD) (31.41%), atrial septal defect (ASD) (11.37%), aortic stenosis (AS) (7.64%), pulmonary stenosis (PS) (7.13%), coarctation of the aorta (CoA) (5.77%), and transposition of the great arteries (TGA) (5.43%), followed by persistent ductus arteriosus (PDA) (4.75%), atrioventricular septal defect (AVSD) and hypoplastic left heart syndrome (HLHS) (4.07% each), tetralogy of Fallot (TF) (3.56%), and pulmonary atresia (PA) (2.38%). A prevalence of less than 0.1/1000 live births was found for the remaining cardiovascular defects.
