RESUMEN
Between february 1992 to January 1994, anatomic correction was performed on 15 patients with transposition of the great arteries and intact ventricular septum. The mean age was 8.3 +/- 2.9 days and the mean weight 3.39 +/- 0.39 Kg. Before the operation, 13 patients (86.6%) received prostaglandin El infusion and 13 patients (86.6%) underwent Rashkind septostomy. Mean aortic cross-clamps was 56 +/- 11 minutes and mean cardiopulmonary bypass was 108 +/- 91 minutes. Hospital mortality rate was 13%. Mean extubation period was mean discharge from ICU was 13.1 +/- 12.3 days and discharge of hospital was 17.8 +/- 7.5 days. The mean followup period was 11.4 months. All the patients remained asymptomatic with adequate psychomotor and ponderal development. All patients remained in sinus rhythm. Pulmonary suture gradient was over 60 mm Hg in five patients (33%). One patient needed reintervention and four pulmonary artery angioplasty (PAA) that was successful. In the midterm follow-up pulmonary stenosis suture was the most common complication. If the stenosis is severe and PAA should be the initial approach.
