Heart valve replacement normally does not affect life expectancy. Survival is related to the patient’s own condition and the type of valve replaced. 1. The physical condition of the patient, if the patient has more serious heart valve lesions and complications before the valve replacement surgery, such as atrial fibrillation, arrhythmia, heart enlargement and other diseases, after the surgery can have a certain degree of improvement, but not fully recovered, these will affect the life expectancy of the patient, but has nothing to do with the surgery itself. If the patient is in good health before surgery, life expectancy is usually not affected. 2. There are two types of replacement valves: mechanical and biologic. Mechanical valves do not have a life expectancy, but anticoagulant medications such as warfarin must be taken at all times to prevent the formation of blood clots. Biologic valves usually have a service life of 10 to 12 years and do not require constant anticoagulation. After 10 years, follow-up should be intensified to determine if there is any insufficient closure or stenosis of the valve. It should be noted that after valve replacement, it is important to have regular follow-ups, examinations, and medications as prescribed by the doctor.
