Resumen

Se presenta el caso de un recién nacido ingresado a los 20 días de vida por insuficiencia cardíaca congestiva gra-ve. El ecocardiograma reveló hipertrofia ventricular iz-quierda con estenosis valvular aórtica crítica y coartación de aorta severa. El diámetro del anillo valvular era de 5,2 mm. En el cateterismo se obtuvo un gradientevalvular de 104 mmHg y de 58 mmHg a través de la coartación, que tenía un diámetro de 1,4 mm.La aorta transversa y el ist-mo presentaban hipoplasia moderada. Tras dos procedi-mientos de dilatación consecutivos,con un intervalo de mes y medio, el gradiente valvular se redujo a 32 mmHg y el de la coartación a 14 mmHg y sdiámetro se incre-mentó a 5,4 mm.

We present a 20-day-old male infant with severe con-gestive heart failur.Echocardiography showed left ven-tricular hypertrophy secondary to critical aortic valve stenosis and severe coarctatio of the aorta. The size of aortic annulus valve was 5.2 mm. At catheterization, the gradient of aortic valve stenosis was 104 mmHgand the gradient through aortic coarctation, measuring 14 mm in diameter, was 58 mmHg. Transverse and isthmic aorta showedmoderate hypoplasia. After two dilatation pro-cedures performed at an interval of 45 days, the pressure valve gradient decreased to 32 mmHg, that of the coarc-tation of the aorta decreased to 14 mmHg and the diame-ter increased to 5.4 mm.
