Mitral valve diseases like mitral stenosis (narrowing) and mitral regurgitation (leakage) can lead to breathlessness, fatigue, leg swelling, and heart failure if left untreated. Even a small valve defect can affect blood flow and reduce heart efficiency. Ignoring symptoms like breathlessness during walking or frequent coughing can be risky. Early diagnosis through tests and timely treatment are key. If you or your loved one experiences these symptoms, please consult your heart doctor. With proper follow-up and care, valve diseases can be managed effectively for a healthier, more active life.
