Valve replacement at the age of 50 usually does not affect life expectancy. Survival time is mainly related to the patient’s condition and the type of valve replaced. 1. If the patient has a structural heart disease or complication before valve replacement, such as arrhythmia, atrial fibrillation, heart enlargement, etc., it will get better after valve replacement but will not be completely reversed, which will affect the patient’s life expectancy, but has nothing to do with valve replacement. 2. For patients younger than 60 years of age, mechanical valve replacement is recommended. Mechanical valves have a longer lifespan, but require lifelong use of anticoagulant medications such as warfarin to prevent thrombosis. 3. Patients over 70 years of age are recommended to have a biologic valve, which does not require lifelong anticoagulation and has a life expectancy that is greater than the patient’s remaining life expectancy. It should be noted that regular follow-up visits to the hospital are required after heart valve replacement.
