Epidemiology of congenital heart disease in the United States.

Data from the National Center for Health Statistics were examined to aid in assessing the burden of congenital heart disease in the United States. In 1979 through 1988 combined, 46,450 deaths were attributed to CHD, 26,319 occurring in the first year of life. Another 14,283 deaths were attributed to other congenital anomalies of the circulatory system. In 1988 through 1990 combined, there were > 300,000 hospital discharges with any diagnosis of CHD, with 2.7 million days of care provided. For infants aged < 1 year, the rate was 13.7 per 1000 live births per year. Another 242,049 discharges had any diagnosis of other congenital circulatory anomalies. In 1983 through 1985, > 700,000 persons reported a history of CHD. In 1989, heart malformations were reported on the birth certificate of 4621 live births in 45 states and the District of Columbia. In 1988 through 1990 there were an estimated 37,445 repairs of atrial and ventricular septa. In addition, 45,635 cardiac catheterizations were performed in patients aged < 5. Average annual percentage declines in infant mortality rates for the period 1979 through 1988 were consistent with an effect of improvements in surgical technique and intensive care. The average annual infant mortality rate for hypoplastic left heart syndrome increased 1.3%, and rates for five causes amenable to treatment such as transposition of great vessels declined. Infant mortality rates in nonmetropolitan areas were higher than in metropolitan areas, suggesting that limited access to care might be associated with mortality.(ABSTRACT TRUNCATED AT 250 WORDS)
