Abstract
ABO blood groups were determined in 404 patients who had cardiac surgery for heart disease; 136 of these patients had rheumatic valvular heart disease and 268 had congenital heart disease. The incidence of each ABO blood group was compared to a control series of 2171 patients by means of the ϰ2 test. There was no statistical difference in the incidence of ABO blood group when patients with congenital and rheumatic valvular heart disease were compared with the control group.
