Radiological signs seen in mitral stenosis are:
§ Backward displacement of esophagus by enlarged left atrium (in lateral view X-ray). Also the earliest sign.
§ Straightening of left heart border due to enlarged left atrium.
§ Double shadow due to enlarged left atrium. Dense right atrial shadow superimposed within fainter left atrial shadow that touches the diaphragm.
§ Splaying of carina (The left main bronchus is lifted up by the enlarged left atrium)
§ Prominent upper zone pulmonary veins (Inverted moustache sign / Antler’s horn sign / Cephalisation pulmonary of blood flow)
§ Enlarged pulmonary trunk (This occurs following the development of pulmonary hypertension)
§ Kerley B lines (indicating fluid collection in the interlobular septa. 1-2 cm in length lines in lung peripheries perpendicular to and extend out to pleural surfaces.)
NOTE: Here is a chest radiograph exhibiting classic findings of chronic mitral stenosis.
