Heart valve stenosis is treated with medication, interventional therapy or prosthetic valve replacement depending on the severity of the stenosis. 1. If the stenosis is only mild, no special treatment is needed. Regular cardiac ultrasound should be performed to monitor the progress of the disease, and attention should be paid to the regularity of life and diet. 2. If the valve stenosis is moderate or severe, it may cause structural changes in the heart, arrhythmia or heart failure. It can be treated with beta-blockers (propranolol, etc.), positive inotropic drugs (digitalis, etc.), diuretics (hydrochlorothiazide, etc.), and drugs to improve ventricular remodeling (captopril, etc.). Interventional therapy can also be used to dilate the stenotic valve with a balloon. 3. If the valve stenosis is severe and affects the patient’s survival. Surgery to replace the prosthetic valve may be performed, with either a mechanical or biologic valve depending on age. It should be noted that when heart valve stenosis occurs, it is important to go to the hospital in time for examination and treatment under the guidance of a doctor.
