Prominent main pulmonary artery and straightening of left border
Prominent main pulmonary artery (MPA) and straightening of left border can be seen in mitral stenosis with pulmonary hypertension. The double atrial shadow expected on the right cardiac border is not seen here. Upper lobe vessels are prominent, indicating pulmonary venous hypertension. Right pulmonary artery (RPA) shadow is also prominent. Left pulmonary artery enlargement as a shadow behind the cardiac silhouette, going down from the MPA segment.
