You have been diagnosed with mitral valve stenosis. This means that the mitral valve, located between the left atrium (left upper chamber) and left ventricle (left lower chamber) of the heart, is stiff and doesn’t open correctly. Because the valve is narrowed, blood must move through a smaller opening. In moderate to severe cases, fluid can build up in the lungs. That can lead to coughing and breathing problems. You can also develop heart rhythm problems, such as atrial fibrillation. Over time, mitral valve stenosis may slowly get worse. Most cases of mitral valve stenosis are caused by rheumatic fever.
Many people with mild mitral valve stenosis who don't have symptoms don't need treatment. In such cases, regular monitoring of the valve with echocardiograms is typically recommended. Sometimes symptoms can be controlled with medicines alone. In some cases, you may need surgery or a minimally invasive catheter-based procedure to repair or replace the mitral valve. Your cardiologist will recommend treatment based on your own condition. Here are things you can do at home.
