Atrioventricular septal defect with common atrioventricular junction, common arterial trunk, and severe coarctation of the aorta in a patient with Down's syndrome.

Atrioventricular septal defect with common atrioventricular junction is rarely associated with either a common arterial trunk or coarctation of the aorta. We report, as far as we are aware, the first case of Down's syndrome with atrioventricular septal defect with common atrioventricular junction, common arterial trunk, and severe coarctation of the aorta.
