A 77-year-old is not necessarily a candidate for heart valve surgery. Heart valve surgery can usually be performed on elderly people who are in good health and do not have other adverse chronic conditions, after evaluation by a physician. Its use is for use on mitral or tricuspid valves with minor lesions, such as rheumatic heart valve disease, where valve replacement is often chosen. If the 77 year old is in good health, and the body indicators are normal at the time of the test results, and there are no other adverse chronic diseases, he or she can generally undergo heart valve surgery. If the elderly are in poor health and have a combination of chronic diseases such as hypertension and diabetes, the patient is generally unable to tolerate major surgery when their condition is not under stable control, so heart valve surgery is generally not recommended for this group of patients. Heart valve surgery carries a certain degree of risk, and a thorough assessment of the patient’s physical condition by a doctor is required before the surgery to determine whether the patient is suitable for surgical treatment.
