It is the almost unanimous opinion of those who have studied aneurysm of the ventricle complicating occlusion of the coronary artery that the diagnosis of this condition is a difficult clinical task. The rarity of occurrence of the lesion has been somewhat overemphasized. Libman1 reported that it was found fifteen times as frequently as Hodgkin's disease, and Applebaum and Nicolson2 found aneurysm of the ventricle to have been present in 57 (or 38 per cent) of 150 cases of occlusive disease of the coronary arteries of the atherosclerotic group. Of the 57 aneurysms, 56 were located in the left ventricle.
Pletnew3 has shown the difficulty of diagnosis by purely physical means; he reported 0.5 per cent successful diagnoses in 300 cases. Kahn,4 in 1922, stated that roentgenographic and fluoroscopic examination are of little aid in the diagnosis of this condition, but more recently several authors5 have detected the sacculation by
