oa Cardiovascular Journal of Africa - Great artery size in infants with large left-to-right intracardiac shunts
Patients with atrioventricular septal defects (AVSDs) are prone to develop pulmonary vascular obstructive disease (PVOD) in infancy earlier than similar patients with ventricular septal defects (VSDs) or atrial septal defects (ASDs). It was hypothesised that this would be reflected in prehilar pulmonary artery hyperplasia. Review of the catheterisation data and angiograms of 34 consecutive patients with AVSD under 1 year of age who underwent repair at our institution was undertaken, and the results compared with 10 patients with secundum-type ASDs and 10 patients with perimembranous VSDs who were matched for age, size and intercardiac shunt ratio (Qp:Qs).
