Abstract
A case is reported of a 67-year-old negro male, who expired after a prolonged course of intractible congestive heart failure. Autopsy revealed multiple fenestrations of both the aortic and pulmonic valves; the right anterior aortic valve cusp was ruptured through the area of a fenestration. Fusion of the commissures of the aortic valve suggesting old rheumatic valvulitis was also noted. Sections of the aortic valve cusp revealed a mucinoid degeneration of the valve substance.
