Understanding Mitral Valve Stenosis: Causes, Symptoms, and Treatment
Mitral valve stenosis is a heart condition characterized by the narrowing of the mitral valve, which regulates blood flow between the left atrium and the left ventricle. When this valve becomes stiff or thickened, it restricts blood flow, causing the heart to work harder to pump blood throughout the body. Over time, this increased strain can lead to complications affecting the lungs, heart rhythm, and overall cardiovascular health.
The most common cause of mitral valve stenosis is rheumatic fever, a condition resulting from untreated strep throat or scarlet fever. Rheumatic fever triggers an inflammatory response that can permanently damage the mitral valve, making it less flexible and prone to narrowing. Although less common, other causes include congenital heart defects, calcium deposits on the valve, and certain autoimmune diseases that affect connective tissue.
Symptoms of mitral valve stenosis often develop gradually and may…
