Aortic valve replacement usually does not affect the patient’s life expectancy. The survival time of the patient is related to the patient’s physical condition and the type of valve replaced. 1. Physical condition: If the patient already has structural changes in the heart such as atrial hypertrophy or other underlying diseases before valve replacement, the patient’s physical condition will improve after valve replacement, but the disease cannot be completely eliminated, and these lesions will affect the patient’s survival time. 2. Types of replacement valves:Mechanical valves have no life expectancy, but anticoagulant medications such as warfarin should always be taken for anticoagulation to prevent the formation of blood clots. Biologic valves have a lifespan of 10 to 15 years and are usually recommended for elderly patients. It should be noted that after aortic valve replacement, it is important to pay attention to the maintenance of the valve, pay attention to diet and lifestyle.
