[Radiological study of congenital mono and bicuspid aortic valves (author's transl)].
Bicuspid aortic valves are much more common than monocuspid valves and diagnosed by A. P. aortography and, above all, lateral views. One may distinguish the true bicuspid valves which include two Valsalva sinuses, often asymmetrical, and bicuspid valves whith a supplementary raphe, the commonest type, in which on angiography, one may distinguish three Valsalva sinuses, one of which is larger than the two others. These cases of bicuspid aortic valve may be associated with other malformations of the aorta or may occur alone. In the latter case, the main risks are aortic valvular stenosis or aortic incompetence.
