Most cases of mild aortic regurgitation do not require any special treatment, and regular follow-up cardiac ultrasound is sufficient. For fast progressing, severe regurgitation, it is necessary to actively find and correct the cause of the disease, the common causes are rheumatic heart disease, infective endocarditis, etc.. To prevent further progression, interventional valve replacement or surgical valve replacement surgery should be used after evaluation by a doctor if necessary. 1. Rheumatic heart disease: usually due to streptococcal infection, thus causing heart valve lesions, may involve the aortic valve, resulting in mild regurgitation. Penicillin, aspirin, methylprednisone and other drugs can be prescribed for treatment, and artificial valve replacement can be performed if necessary. 2. Infective endocarditis: pathogenic microorganisms move to the heart through the blood circulation, caused by endocardial inflammatory lesions, will involve the aortic valve, resulting in mild regurgitation. It can be treated with penicillin, amoxicillin, gentamicin and other medications as prescribed by the doctor, and surgically if necessary. When the aortic valve mild regurgitation, it is recommended to consult the cardiovascular internal medicine in time, after the doctor comprehensive assessment of the condition for symptomatic treatment.
