Acute aortic regurgitation occurs in:
The correct answer is
Infective endocarditis
Causes of Acute Aortic Regurgitation
Acute aortic regurgitation (AR) is a serious condition where the aortic valve doesn't close properly, allowing blood to leak back into the left ventricle from the aorta.
- Infective Endocarditis: This is a primary cause of acute aortic regurgitation. Infection damages the leaflets of the aortic valve, causing rapid destruction and severe regurgitation. The infection can directly destroy valve tissue or lead to large vegetations that impede valve closure.
- Other conditions like Ankylosing spondylitis, Marfan's syndrome, and Rheumatoid arthritis are more commonly associated with chronic aortic regurgitation due to gradual changes in the valve or aorta, rather than acute destruction.
Therefore, infective endocarditis is a direct and common cause of acute aortic regurgitation.
