Mitral valve prolapse in children usually requires surgical treatment. Mitral valve prolapse refers to lesions of the mitral valve membrane or the tendon cords and papillary muscles below the valve, etc. Surgery is usually required for mitral valve prolapse in children. Typical symptoms of mitral valve prolapse in children may include palpitations (rapid heartbeat, often accompanied by panic), intermittent dull pain in the anterior chest area, and dyspnea. Prompt treatment can prevent serious complications from becoming life-threatening in children, such as mitral regurgitation, atrial fibrillation, or infective endocarditis. Children with mitral valve prolapse that interferes with normal life and causes the body to experience symptoms such as heart enlargement and increased mitral regurgitation should require early surgical treatment. If you encounter any of the above problems, it is recommended that you consult with a medical professional in order to ensure that your child’s health is the primary concern.
