The relative incidence of rheumatic valve disease in New York and Costa Rica and its bearing on the rheumatic origin of calcareous aortic stenosis

摘要: Abstract The incidence of rheumatic endocarditis the mitral valve alone, and aortic valves together, in three independent series autopsies is compared. Differences total valvular lesions were noted each series. These differences cannot be attributed to racial or geographical factors since two represent cases from essentially same types population New York area. However, relative type lesion constant Mitral stenosis more common women than men calcareous deforming lesions, limited valve, also determined autopsy found vary constantly with In males, together both valves, are about one-half times as valve. Lesions only males involve an older age group do other lesions. only, groups surviving longer 50 years series, relatively for entire however.
