Anatomical aortic valvular stenosis usually implies stiffening of the leaflets or mutual cross adherence of their free margins with consequent reduction in the size of the valve aperture due to commissural obliteration.Since aortic stenosis is one of the most common of the various valvular deformities produced by rheumatic fever, being second in frequency
