Overview

Chest X-ray in a patient with mitral stenosis might reveal left atrial enlargement. Chest X-ray findings include double right heart border, a prominent pulmonary artery (suggestive of an elevation in the pulmonary artery pressure), and kerley lines (suggestive of interstial pulmonary edema).

Shown below is a chest X-ray in a patient with mitral stenosis. Note the following findings:

In blue: outline of the heart (mildly enlarged)
In yellow: double right heart border
In red: straightening of the left border of the heart suggestive of enlargement of the left atrium

In addition, the chest X-ray reveals Kerley lines.
