Mitral Valve Stenosis - Exams and Tests


Electrocardiogram is used to measure the electrical activity in the heart. Small pads or patches 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.
