A 78-year-old man with a history of recurrent syncope undergoes surgery for aortic valve disease. A hard, markedly deformed valve is observed, but the patient expires during surgery. The aortic valve at autopsy is shown in the image. What is the appropriate diagnosis?
Bicuspid aortic valve
Calcific aortic stenosis
|D.||Hypertrophic subaortic stenosis|
Answer : C Calcific aortic stenosis
The aortic valve shows calcific aortic stenosis in a three-cuspid valve in an
elderly person. There is no commissural fusion. Calcific aortic stenosis refers to a narrowing of the aortic valve orifice as a result of the deposition of calcium in the valve cusps and ring.
There are three main causes of calcific aortic stenosis:
b.senile calcific stenosis, and
c.congenital bicuspid aortic stenosis.
Calcific aortic stenosis is related to the cumulative effect of years of trauma due to turbulent blood flow around the valve.
Bicuspid aortic valve (choice B) is incorrect because three valve cusps are shown.
