Q. How to investigate aortic stenosis by Roentgenogram?

Cardiac enlargement does not occur in pure compensated aortic stenosis. Post stenotic dilatation of aorta may be seen. Fluoroscopy may reveal calcified aortic valve and often concomitant mitral annular calcium. Decompensated aortic stenosis may present with signs of left ventricular dilatation and pulmonary venous hypertension. Gross left atrial dilatation on roentgenogram should suggest associated mitral valve disease. Absence of ascending aortic dilatation gives a clue that valve may not be the site of stenosis.
