Diagnosis of Aortic Stenosis

Calcification of the Left Auricle

“…Differentiation of this lesion from other heart conditions with calcification, myocardial infarction, calcification of coronary arteries, mural thrombi in mitral stenosis and after myocardial infarction, calcification of ventricular and aortic aneurysms and of the mitral and aortic valves, should be relatively simple, and might be helped by tomography of the heart (Davies and Steiner, 1949, Epstein, 1949, Lewes, 1951, and Moses, 1951), except in the case of constrictive mediastino‐pericarditis or a calcified pericardium. In these later conditions differential diagnosis may be impossible if calcification is restricted to the posterior inferior area of the heart as seen in the R.A.O.…”
