Summary

Right ventricular dominance was observed in 22 (6.6%) out of 332 patients with atrioventricular septal defects. Their mean age was 2.24 ± 2.73 months. Chromosomal anomalies were seen in only three patients (Down's syndrome in two and trisomy nine in one). Seventeen patients underwent surgical treatment. A pulmonary artery banding was performed in eight of them with one long-term survivor who underwent a successful staged orthoterminal repair. A Norwood-type of palliation was attempted in four without success. Biventricular repair was performed in four additional patients with two mid-term survivors, in one of whom the patch used for closure of the atrial septal defect was fenestrated. One patient underwent successful heart transplantation at seven months of age. Pathophysiological problems and surgical options are discussed.
