Two children with tetralogy of Fallot and supravalvular mitral membrane are reported. In both, the diagnosis was established before surgery. In the first case, clinical data suggested the associated mitral lesion and a two-dimensional echocardiogram demonstrated a supravalvular membrane. In the second patient, mitral obstruction was diagnosed by Doppler echocardiography and the supravalvular membrane was visualized by means of the angiographic study. Despite the rare association of both malformation, the importance of its clinical recognition is mainly related to the surgical correction of both lesions.

[Double-outlet left ventricle].

Two cases of double-outlet left ventricle with ventricular septal defects and pulmonic stenosis are described. Both had atrial situs solitus, one with concordant and another with discordant atrioventricular connections. Considering the clinical behaviour of the malformation, the diagnosis is difficult. Although the echocardiographic findings suggest the abnormality, angiocardiography is the best procedure for the accurate diagnosis.
