The number of years of survival after heart valve replacement is mainly related to the type of valve the patient has had replaced and how many complications of valvular heart disease occur, and should be analyzed on a problem-specific basis. If a mechanical valve is used, it is available for life in in vitro trials, but after being placed in the human body, certain changes may occur, usually extending the patient’s life by 30-40 years, but because the valve replacement can induce thrombosis, the patient will need to take drugs such as warfarin for life, as well as monitoring the INR value. If a biologic valve is used, the duration of use is approximately 15 years. Elderly patients over 50 years of age or in cases where they cannot be monitored for long periods of time may choose a valve based on their economic conditions and personal wishes. Patients need to take medications and prevent infection as prescribed after heart valve replacement, and can be appropriately active, emotionally stable, and regularly reviewed.
