In developing countries, rheumatic disease is the most common cause of aortic insufficiency and may present in second or third decade of life. While in western countries where rheumatic disease is rare, aortic insufficiency may be due to congenital(bi-cuspid valve) or degenerative disease which may present in fourth or sixth decade. Endocarditis and aortic dissection being other causes.
The prevalence of aortic insufficiency increases with age[1] [2]with higher severity in men than in women. [3] [4]
There are two broad underlying causes of aortic regurgitation:
- Disease of the aortic valve itself and
- Disease of the aortic root leading to dilation and regurgitation of the aortic valve
Aortic regurgitation secondary to dilation of the ascending aorta has overtaken valvular aortic disease as the most common cause of aortic regurgitation.
