oa South African Medical Journal - Idiopathic dilatation of the pulmonary artery*
1. Four cases of idiopathic dilatation of the pulmonary artery are descriptionbed. 2. The differential diagnosis is discussed with special reference to congenital cardiac anomalies amenable to surgical treatment. 3. Previously reported cases are quoted. 4. The importance of cardiac catheterization and angiocardiography in the diagnosis of these cases is stressed. 5. The difficulty or impossibility of differentiating mild pulmonary valve stenosis from idiopathic pulmonary dilatation even with the aid of these special investigations is emphasized.
