Mild aortic regurgitation does not require any treatment. The aortic valve is the valve between the left ventricle and the aorta. When the heart is contracting, the aortic valve should open so that blood from the ventricles can smoothly hit the aorta and supply all organs of the body. During diastole, the aortic valve should close to prevent blood from flowing backwards into the left ventricle. If the aortic valve is not closed properly, it can cause mild regurgitation of the aortic valve. During diastole, a small amount of blood in the aorta will regurgitate into the left ventricle, and mild regurgitation will not cause any symptoms. The common cause of mild aortic regurgitation is degenerative aortic valve degeneration. It is recommended to develop good lifestyle habits, control blood pressure, blood lipids and blood sugar, and slow down the process of aortic valve calcification to avoid aggravating aortic regurgitation.
