[Hypertrophic myocardiopathy and tetralogy of Fallot. Study of 2 cases]

The authors report two observations of concentric hypertrophic cardiomyopathy associated with Fallot's tetralogy in one case and with pulmonary atresia complicated by atrial septal defect in the other. The association of Fallot's tetralogy with hypertrophic cardiomyopathy is rare, as only 5 cases have been reported in the literature. In this connection, the mechanism of myocardial hypertrophy and the therapeutic problems posed by this association are discussed.
