Diphtheria primarily affects the respiratory system and can lead to complications such as myocarditis, which may impact the heart, including the mitral valve. The inflammation of the heart muscle can result in functional impairment of the valve, potentially leading to regurgitation or other cardiac issues. However, direct effects on the mitral valve itself are less common and typically arise as part of broader cardiac involvement rather than a primary consequence of diphtheria.
