In 1954, Mitchell et al.(1) reported on 40 years of experience with clinical features of 533 cases of aortic stenosis managed at the Peter Bent Brigham Hospital of Boston, Massachusetts. This patient series spanned the development of mercurial diuretics, surgical cure for aortic stenosis, and penicillin, advances that have transformed the epidemiology and prognosis of aortic stenosis. Several remarkable observations of this study remain central to the findings reported in this issue of the Journal. Mitchell et al.(1) noted significantly shorter expected survival after the onset of symptoms. The average lifespan was 4 years after the onset of angina, 3.5 years after the onset of congestive heart failure, and 3 years after syncope. Among patients with witnessed deaths, 35% died of congestive failure, 20.1% of subacute bacterial endocarditis, 2.3% of myocardial infarction, and 18.7% of sudden death; the remaining causes of death were noncardiac. Sudden death tended to occur in the later stages of disease and was associated with history of angina. However, autopsy examinations revealed that sudden death frequently occurred in the absence of
