There are many types of heart valve disease, and if symptoms are present but not treated, they may get worse and even lead to death. Common types of heart valve disease include mitral stenosis and insufficiency of closure, aortic stenosis and insufficiency of closure, and polyvalvular disease, whose main cause is rheumatic fever. If you are diagnosed with heart valve disease but have no symptoms, your condition may not change, but you need to be reviewed regularly. If symptoms such as hemoptysis, dyspnea, and angina are not treated, they may become more and more serious, along with complications such as arrhythmia, bleeding, atrial fibrillation, pulmonary edema, and thromboembolism, and ultimately death from heart failure, thromboembolism, and infective endocarditis, or even death within a short period of time, so it is recommended that heart valve disease be treated as early as possible after it is detected.
