Sequelae of heart valve replacement surgery can cause arrhythmia, arrhythmia, heart murmur, and cardiac insufficiency. Heart valve replacement surgery is a major surgery with high technical and equipment requirements. After valve replacement, the symptoms of shortness of breath and dyspnea can be improved, and the quality of life can be improved appropriately. However, symptoms such as arrhythmia, heart murmur and coagulation may remain for a short period of time after the surgery. Therefore, it is important to take regular anticoagulant medication after the surgery, and long-term medication that nourishes the heart muscle, protects the heart, and prevents rejection to maintain the treatment. Patients who have had their heart valves replaced have an improved quality of life, but must be careful to avoid strenuous exercise, emotional stress and other triggering factors, and need to pay attention to heart function at all times.
