Pulmonary valve stenosis and hemophilia A. Report of three cases and discussion of a possible genetic linkage.
We treated three unrelated patients with hemophilia A and congenital pulmonary valve stenosis. In two patients, the occurrence of the cardiac malformation was sporadic and in one familial. The coexistence of hemophilia A and pulmonary valve stenosis might suggest a genetic linkage for both disorders. Review of the literature supports the hypothesis that the inheritance of pulmonary valve stenosis is dominant and X-linked.
