Aortic stenosis is one of the most common and most serious valve disease problems1.
It is estimated that 1 in 8 elderly Australians has Aortic Stenosis2. Up to 50% of people who develop severe Aortic Stenosis symptoms will die within an average of two years3 if they do not have their aortic valve replaced.
Aortic stenosis is defined as a narrowing of the aortic valve opening. Aortic stenosis restricts the blood flow from the left ventricle to the aorta and may also affect the pressure in the left atrium4.
Aortic Stenosis is the increased pressure load imposed by aortic stenosis results in compensatory hypertrophy of the left ventricle (LV). With time, the ventricle can no longer compensate, causing secondary LV cavity enlargement, reduced ejection fraction (EF) and decreased cardiac output. The result is an increase in exertional syncope, exertional angina and breathlessness over time5.
The severity of aortic stenosis is determined by the calcification of the aortic valve leaflets
