Rheumatic heart disease is a type of organic heart disease caused by a hypersensitivity reaction in the body due to infection by Streptococcus pyogenes. This leads to pathological changes in the heart valves, including the tricuspid and mitral valves, resulting in stenosis or insufficiency which affects hemodynamics. This condition is known as rheumatic heart disease. Patients with rheumatic heart disease should actively seek treatment under the guidance of a doctor in the early stages to control the occurrence of complications.
