Mitral Valve Stenosis - Exams and Tests

Mitral valve stenosis often has no symptoms in its early stages. It may not be diagnosed until you've had the disease for some time. One or more complications may lead to its diagnosis.

The first sign of mitral valve stenosis could be a heart murmur that your doctor hears during a routine checkup.

Carotid Artery Disease: Causes, Symptoms, Tests, and Treatment

Carotid artery disease is also called carotid artery stenosis. The term refers to the narrowing of the carotid arteries. This narrowing is usually caused by the buildup of fatty substances and cholesterol deposits, called plaque. Carotid artery occlusion refers to complete blockage of the artery. When the carotid arteries are obstructed, you are at an increased risk for a stroke, the third leading cause of death in the U.S.

A review of your medical history and a physical exam can help your doctor find out if you have mitral valve stenosis. Your doctor also can use them to plan your treatment.

Medical history

Your doctor will ask about your lifestyle, activity level, and family health history. Your doctor will want to know about your symptoms. He or she will ask if you have ever had:

Physical exam

During the physical exam, the doctor will:

  • Listen for a certain heart murmur and other sounds that indicate a heart valve is not working right.
  • Take your blood pressure.
  • Check your pulse.
  • Look for swelling that can be a sign of too much fluid in your body.

Echocardiogram

An echocardiogram is used to find out if you have mitral valve stenosis and to see how bad it is. Your doctor can check your heart valve and take pictures of your heart.

In transesophageal echocardiography, a device is inserted down your throat and into your esophagus to make pictures of your heart. This may be done if your doctor wants to see a different view of your heart.

You will likely have regular echocardiograms so your doctor can keep track of any changes in your condition. Your doctor may recommend an echocardiogram every year if you have severe stenosis, every 1 to 2 years if you have moderate stenosis, or every 3 to 5 years if you have mild stenosis.1

Electrocardiogram

Electrocardiogram is used to measure the electrical activity in the heart. Small metal discs called electrodes are attached to your chest, arms, and legs. The electrodes are connected to a machine that translates the electrical activity into line tracings on paper. Your doctor looks at the tracings to check for problems.

Chest X-ray

A chest X-ray may show evidence of mitral valve stenosis. The test may show enlargement of the upper left heart chamber (left atrium) or the pulmonary arteries. Calcium deposits on the heart valves sometimes may be seen, especially if the buildup is severe.

Cardiac catheterization

Cardiac catheterization is usually done before any surgery for mitral valve stenosis to evaluate your heart, the degree of stenosis, and the health of your coronary arteries. Knowing the condition of the coronary arteries may affect later treatment decisions for stenosis.
