Comment
Osler's pathologic description of the case is given in Case V of the Montreal General Hospital Reports 1880, I: 328. Clinical details are absent because the notes were "mislaid"; however, he indicates that the 45 year-old man had "the usual symptoms of severe aortic valve disease". According to Osler, the valve was incompetent ("water pours through with great freedom"). His illustration聽and this specimen聽fit well with acute infectious endocarditis superimposed on a congenitally bicuspid valve.
