[Endocardial cushion defect without ostium primum atrial septal defect associated with tetralogy of Fallot (author's transl)]. / Defecto de cojines endocárdicos sin CIA-OP asociados a tetralogía de Fallot.

A case of endocardial cushion defect without ostium primum atrial septal defect associated with tetralogy of Fallot is presented. The echocardiogram is specially interesting showing two atrioventricular valves recorded simultaneously without an intervening ventricular septum, mitral continuity with the posterior semilunar valve and impossibility of recording the anterior semilunar valve. Findings similar to those of single ventricle with pulmonary stenosis. The anatomopathological findings and their possible embryonic basis are analyzed.

[Double outlet left ventricle with pulmonary atresia]. / Ventricule gauche à double issue avec hypoplasie ventriculaire gauche.

A case of double outlet left ventricle with pulmonary atresia is reported. The hypoplasia of the left ventricule produced by the almost total absence of its trabecular zone has not been previously reported.
