Aortic atresia is rare in the setting of a normally developed left ventricle with a ventricular septal defect. In this combination, as far as we know, it has been described only with concordant ventriculo-arterial connections, for which seven one-stage biventricular repairs have now been described. We describe here the case of a 3 1/2-month-old male infant with a similar combination but with discordant ventriculo-arterial connections and severe pulmonary hypertension. It was the right ventricle which achieved normal size in this arrangement, presumably because of the ventricular septal defect. One-stage biventricular correction was accomplished, employing a single pulmonary allograft, aided by massive doses of Prostaglandin E1. As far as we know this is the first report of the combination of aortic atresia, discordant ventriculo-arterial connections, a ventricular septal defect and balanced ventricles. We complement our surgical account, nonetheless, with a description of a comparable specimen from our anatomic museum. |
