Overview

Gross anatomy dissection may be used as a diagnostic tool in the evaluation of aortic stenosis. Common findings associated with aortic stenosis include left ventricular hypertrophy and heart block.

Pathological Findings

Pathological findings of congenital or acquired aortic stenosis in adults results in thickening and calcification of aortic valve. Following patterns may be seen:^[1]

Calcified bicuspid valve involving anterior or posterior cusps
Calcified aortic valve cusps with fusion of commissures seen in post rheumatic cases
Degenerative calcific aortic stenosis which shows sinuses of valsalva filled with calcium deposits seen in age >70
