1, what is heart valve disease: in short, it is the heart valve opening and closing problems, resulting in blood flow forward blocked, or abnormal regurgitation, will cause the heart burden, heart enlargement, and ultimately heart failure. In general, the mitral and aortic valves play the largest role in the heart, so they are also the most susceptible to disease. Symptoms and manifestations of valvular disease mainly include: chest tightness after activity, panic, shortness of breath is the most common symptom, some manifestations of fatigue, dizziness, sweating, chest pain, coughing, coughing up sputum, abdominal distension after eating, lower limb edema, and in the later stage of serious night can not lie down or even sit up and breathe, etc. Most of them can be found in routine physical examination. Most of the routine physical examination can be found in the heart murmur, confirm the diagnosis needs to be heart ultrasound examination. 2, how to treat heart valve disease: most valve diseases require surgery. Early mild lesions can be controlled by medication, but most of the lesions will continue to progress so that the heart function is seriously affected, and if the heart function fails, the time for surgery may be missed. As long as surgery is performed in a timely manner, the success rate and long-term results are satisfactory. There are two types of surgery: valve replacement and valve repair. In valve replacement surgery, the diseased valve is removed and replaced with an artificial heart valve. Valve repair surgery retains its own valve structure and does not require anticoagulation therapy, so its long-term results and quality of life are very high. 3.Types of artificial heart valves: There are two main types of valves used in valve replacement surgery, biological valves and mechanical valves. Biological valves are derived from living organisms and are closer to the body’s own valves; mechanical valves are made of carbon or other materials. Both have their advantages and disadvantages. The advantage of biologic valves is that they do not require lifelong anticoagulant medication, while the disadvantage is that they are not durable and generally have a lifespan of about 15 years. Therefore, biologic flaps are generally used in elderly patients over 65 years of age and in young women with fertility requirements. Mechanical flaps have the advantage of being long-lasting and can be used for life without replacement; the disadvantage is that they require lifelong use of anticoagulant medications (warfarin). Different patients can choose different types of valves according to their needs.
