Mild aortic regurgitation usually does not require special treatment, and regular follow-up cardiac ultrasound is recommended for observation. This condition may be a physiologic condition, and if it is a pathologic condition, usually mild regurgitation, and will not affect the structural function of the heart. The aortic valve is a valve structure between the left ventricle and the aorta. If there is regurgitation, it means that the blood ejected from the left ventricle into the aorta returns to the left ventricle, resulting in the left ventricle repeating its work. For mild regurgitation, observation is sufficient, and regular cardiac ultrasound is recommended. It is usually recommended to review the cardiac ultrasound once every 3 to 6 months. In case of severe regurgitation, surgical valve replacement or medical transcatheter aortic valve implantation may be required. If mild aortic regurgitation is present on examination, and the patient has no other problems with the structure of the heart and no cardiac function abnormalities, regular cardiology visits for review of the cardiac ultrasound are recommended. If there are other heart diseases, actively treat their primary heart disease to control the condition and try to avoid the aggravation of regurgitation.
