Mitral Valve Stenosis: Understanding the Causes, Symptoms, and Treatments
Mitral valve stenosis is a heart condition that affects the flow of blood between the left atrium and the left ventricle. The mitral valve, which lies between these two chambers, functions as a gateway that opens and closes to regulate blood flow. When this valve becomes narrowed or stiff, it restricts the passage of blood, causing the heart to work harder and potentially leading to serious cardiovascular complications.
The most common cause of mitral valve stenosis is rheumatic fever, which can occur after an untreated or poorly treated strep throat infection. The inflammation caused by rheumatic fever may damage the mitral valve leaflets, leading to thickening or scarring over time. In some cases, the condition can also result from congenital abnormalities, calcium buildup on the valve, or radiation therapy to the chest area.
