Endocarditis in infancy is rare, but when it occurs it is more often associated with a septic than with a rheumatic process.1 Many such involvements are not discovered until autopsy, because the heart frequently reveals no enlargement and no murmurs. When murmurs do occur, one's first thought is of congenital malformation of the heart. In the case reported here every one who listened to the heart commented on the fact that the murmur sounded more like that of an acquired lesion than like that of one of congenital origin; even so no one gave serious consideration to the possibility of infectious endocarditis.
