Calcific aortic stenosis, abbreviated CAS, is a very common disease of the aortic valve. It typically afflicts the elderly.
In younger individuals the valve is typically abnormal (bicuspid aortic valve or unicuspid aortic valve).
General
- Somewhat similar to atherosclerosis; however, considered a separate entity.[1]
- Mitral valve is usually normal.
- Most common cause of aortic stenosis.
DDx of aortic stenosis:
- Calcific aortic stenosis.
- Bicuspid aortic valve with calcific aortic stenosis.
- Rheumatic heart disease.
Clinical (mnemonic SAD):
- Syncope.
- Angina.
- Dyspnea (shortness of breath) - first symptom.
Gross
- Thickened, calcific appearing valve.
Drop test:
- Makes a "ting" sound when landing on a metal surface.
Microscopic
Features:[2]
- Dystrophic calcification[3] - affects the valsalva side of the valve.
- It affects the fibrosa.
- Primarily at the base of the valve, i.e. there is relative sparing the free edge.
Note:
- There should be no neutrophils and no microorganisms.
- An expanded spongiosa layer may be seen in the context of calcification.[citation needed]
DDx:
- Infective endocarditis - inflammatory cells (esp. neutrophils), microorganisms (e.g. cocci).
- Bicuspid aortic valve.
- Rheumatic heart disease.

AORTIC VALVE, VALVE REPLACEMENT: - CALCIFIC AORTIC STENOSIS.
Micro
The sections show valve tissue with marked calcification of the fibrosa layer. No neutrophils are identified. No microorganisms are identified with routine stains.
