In the following conditions, aortic stenosis can coexist with aortic regurgitation (aortic incompetence).
- Congenital bicuspid aortic valve
- Calcific degeneration of aortic valve
- Atherosclerotic degeneration of aortic valve
- Infective endocarditis in a case of aortic stenosis
H0w aortic stenosis and regurgitation can coexist?
- It can be explained by the following analogy
- Consider a normal aortic valve to be a door
- It closes and opens completely during each cardiac cycle
- Now consider the door to be stuck in the mid position
- It neither closes completely nor opens completely
- Similarly, when the aortic valve is deformed, both stenosis and regurgitation can coexist
