What is Aortic Regurgitation

Aortic regurgitation is a heart condition in which the valve between the left ventricle and the aorta malfunctions. Possible structural causes of aortic regurgitation include the aortic valve itself is deformed and malfunctions or a heart deformity near the valve affects the valve’s functioning.

In acute aortic regurgitation, symptoms come on quickly since the heart has not had the time to compensate. In chronic aortic regurgitation, symptoms develop more gradually and may not be noticed for years until the condition worsens. In the case of severe acute aortic regurgitation, especially due to trauma, immediate surgery may be needed.
