title: [Isolated stenosis of the aortic orifice].
abstract: Five known to-day causes of the isolated aortal valve stenosis are reviewed: 1) atherosclerosis, 2) premature calcinosis of congenital bicuspidalis aortal valve; 3) rheumatism; 4) infectious endocarditis; 5) mesenchymal dysplasia. The authors consider that aortal valve calcinosis developing against the background of valve atherosclerosis complicates the above diseases and differential diagnosis of aortal stenosis causes.
