Once diagnosed with rheumatic heart disease, a patient’s life expectancy is related to the severity of the rheumatic heart disease and the outcome of surgery and conservative treatment. If one develops rheumatic heart disease and has surgery in a timely manner, life expectancy is within 10-20 years after surgery. If rheumatic heart disease has become too severe to be treated surgically, life expectancy is likely to be within 5 years. Therefore, once rheumatic heart disease occurs, it is important to go to the hospital for a comprehensive examination, which is mainly a cardiac ultrasound, which can assess the degree of valve damage caused by rheumatic heart disease, as well as the condition of heart function, and make an assessment plan for the next step of treatment based on the results of the examination.
