[Angiographic study of congenital aortic stenosis (author's transl)]

Left ventriculography is of great interest in the diagnosis and prognosis of congenitalaortic stenosis. It permits one to distinguish valvular stenosis, which is the commonest type, from sub-valvular stenosis, of which there exist 5 main type; type I and II are the commonest, they have a better prognosis than types III and IV. Sub-sigmoid aortography shows the appearance of the sinus of Valsalva, thus whether there exists a tricuspid or bicuspid aortic valve. In all cases, one should seek stenosis at various levels of the aortic outlet and possible myocardiography of the left ventricle, the frequency of which is well known, together with the poor prognosis.
