Heart valves are relatively easy to repair, and current heart valve surgeries are usually minimally invasive and do not have a major impact on the body. Heart valve repair usually refers to cardiac valvuloplasty, the principle of which is to repair already damaged valves, usually for less severe lesions of the mitral and tricuspid valves, the biggest advantage of valve repair is that the repaired valves do not need to undergo lifelong anticoagulation, and do not need to monitor the coagulation function on a regular basis. Prosthetic valves can also be implanted to repair heart valves. The surgery is usually less difficult and relatively fixed, and the shape and function of the valve can be restored after the surgery, but it is necessary to do a good job of preventing recurrence after the surgery, and it is necessary to take oral anticoagulation with warfarin, and it is usually anticoagulated for 3 to 6 months for patients who have a bioprosthetic valve, while patients who have a mechanical valve usually need to be anticoagulated for the rest of their lives.
