The survival time of patients after heart valve surgery is related to a variety of factors and there is no precise answer, such as the patient’s own condition (including the status of heart function, whether it is combined with other diseases), whether it is aggressively treated after the operation, and so on. If we compare the heart to an engine, valves, especially the replaced mechanical or biological valves, are part of the engine. If the patient’s own condition is good, the postoperative treatment and medication are active, and there are no other serious diseases, they can be applied for a very long time, and it will not affect the patient’s life expectancy. After the operation, the patient carries out a low-salt, low-fat diet, regular aerobic exercise, regular postoperative medication and review under the guidance of the doctor to try to prolong life.
