Mitral Valve Stenosis

Mitral valve stenosis occurs when the mitral valve opening is narrowed and therefore smaller than normal.  The narrowed opening blocks the blood flow between the left chambers of the heart, causing the heart to work very hard to pump blood through it. Left untreated, it can lead to heart failure, arrhythmia, blood clots and other serious conditions.

Causes

Mitral valve stenosis is most common in adults who had the infection known as rheumatic fever when they were younger. The infection can damage the mitral valve. In some cases, mitral valve stenosis is associated with aging. It can also be caused by a congenital heart defect.

Symptoms

• Chest pain
• Shortness of breath
• Frequent respiratory infection
• Heart palpitations

Diagnosis & Treatment

Tests such as echocardiogram, electrocardiogram, Holter monitor or transesophageal echocardiogram may be ordered in order to confirm a diagnosis of mitral valve stenosis. Treatment generally involves valve repair or replacement.
