Congenital Malformations of the Heart and the Great VesselsPrevalence, Incidence, and Life Expectancy in San Francisco

JAMA. 1963;183(4):241-244. doi:10.1001/jama.1963.63700040001010

WHEN epidemiologic consideration is given to the problem of congenital malformations of the heart and great vessels, 3 basic questions arise: (1) how significant is the problem in a community? (2) what is the probability of being born with a cardiovascular defect? and (3) to what extent is life expectancy modified by the presence of a congenital cardiovascular defect?
