The calcified nodular deformity of the aortic valve

Cardiac Pathology in the Horse

“…Neither were the lesions similar to human calcific aortic disease (Clawson, Noble andLufkin 1938, Karsner andKoletsky 1947, Sell andScully 196.5) for calcification was not a feature of the changes in equine aortic valves although it was seen not uncommonly i n association with lesions, probably of parasitic origin, in the aorta and even in the aortic sinuses.…”

Aortic Stenosis and the So‐Called Rheumatic Valvular Diseases in a Postmortem Material

“…I n the American statistics by Karsner et al (15,1947) and by Clawson et al (6,1938), which in Table 4 have been recorded for comparison, a lower average death age is found, so that the majority of their cases have died about one decade earlier than the cases in the present series. The same can be found in Contratto's and Levine's material from 1936 (9).…”

Diagnosis of Aortic Stenosis

“…The incidence of all cases of aortic stenosis (with and without other valvular lesions) in the present series agrees precisely with the findings of McGinn and White (1934) in 6,800 routine-necropsies valvular disease. Clawson et al (1938) found that calcified nodular deformity of the aortic valve constituted 41 % of valvular deformities and 31.5% of all rheumatic heart disease. Finally, Kumpe and Bean (1948) identified isolated calcareous aortic stenosis in 0.72% of 15,016 necropsies, comparable to the present findings of nearly 1 %.…”
