The treatment of moderate-to-severe aortic stenosis needs to be decided according to the clinical manifestations, and can be categorized into conservative treatment and surgical treatment. Conservative treatment of moderate-to-severe aortic stenosis currently favors asymptomatic patients who do not require treatment and are followed up regularly with follow-up examinations (cardiac ultrasound, etc.) every 6 to 12 months, while avoiding strenuous physical activity. Surgery is required once symptoms appear, and typical symptoms include dyspnea, angina, and syncope. The first symptoms are exertional dyspnea, which can progress to pulmonary edema as the disease progresses. Surgery should be considered for moderate-to-severe aortic stenosis whenever clinical symptoms occur, and commonly used surgical procedures include prosthetic valve replacement, direct visualization of the aortic valve separation, percutaneous aortic ball valvuloplasty, percutaneous aortic valve replacement, and so on. Aortic valve stenosis symptoms, if not actively dealt with, the development of the disease is faster, the mortality rate is higher, so once diagnosed, should be treated as soon as possible to avoid the development of the disease caused by the adverse consequences.
