Overview

Chest X-ray may be used as a diagnostic tool in the evaluation of aortic stenosis. Findings associated with aortic stenosis include left ventricular enlargement and calcification of the aortic valve.

Chest X Ray

Chamber Enlargement:

• Chest X-ray may show hypertrophied left ventricle if there is aortic stenosis. In later stages of disease, the left ventricle dilates and the patient may have signs of pulmonary congestion on X-ray.
• In case of severe aortic stenosis for a long time, the left atrium, the pulmonary artery, and the right side of the heart may become enlarged too.

Shown below are images of chest X-rays showing left ventricular enlargement due to aortic stenosis.

Calcification:

• Calcification of the valve is found in nearly all adult patients who have significant aortic stenosis.
• If calcification of the aortic valve is present on a chest x ray of an adult, the aortic valve gradient is usually greater than 50 mm Hg.
