With current medical conditions, valve damage in rheumatic heart disease cannot be cured with medications, and the progression of the valve will continue to worsen once the rheumatism is active. In other words, once a patient with rheumatic heart disease needs treatment, it is recommended that the patient actively undergo surgical treatment to replace the diseased valve with an artificial heart valve, including a metal valve or a biological valve. After metal valve replacement, long-term oral warfarin may be required to prevent the formation of blood clots. In the case of biologic valves, short-term oral warfarin is sufficient after replacement, and long-term oral warfarin prophylaxis is not required. They both have advantages and disadvantages, but in any case, conservative treatment is not too effective for this disease, and only through aggressive surgical procedures can a better result be achieved.
