Cyanosis and unrecognised atrial septal defect in children
Abstract:
Two unusual cases of cyanosis and atrial septal defects are presented. Relative hypoplasia of the right ventricle was an associated feature. In both cases cyanosis was the presenting symptom and the usual clinical signs of atrial septal defect were absent. Chest x-rays and electrocardiograms were normal and the correct diagnosis was not made until after cardiac catherisation.
