Severe aortic valve stenosis treatment is mainly surgical treatment, after the operation need to use drugs for auxiliary treatment. 1. Surgical treatment: mainly aortic valve replacement, percutaneous aortic valve balloon angioplasty, aortic valve separation under direct visualization, and so on. (1) Aortic valve replacement: Surgery is recommended to replace the prosthetic valve when severe stenosis and symptoms occur. (2) Percutaneous aortic valve balloon angioplasty: The aim is to reduce stenosis and symptoms. (3) Directly visualized aortic valve dissection: For patients with severe stenosis of the aortic valve, the valve is separated under direct visualization in the state of deformity and calcification. (4) Minimally invasive transcatheter aortic valve replacement: it can reduce stenosis and symptoms, and this procedure can reduce complications. 2. Medication-assisted therapy, commonly used are antibiotics and anticoagulants. (1) Antibiotics: such as penicillin and clindamycin, used to prevent and treat infections. (2) Anticoagulants: such as warfarin and low molecular heparin are used to prevent blood clots. If severe stenosis of the aortic valve is diagnosed, timely consultation and standardized treatment are recommended. Specifically to follow the doctor’s prescription for treatment.
