Mitral aneu­rysm is com­monly asso­ciated ­with infec­tious endo­car­ditis of the ­aortic ­valve. In ­rare ­instances, it is asso­ciated ­with ­other under­lying inflam­ma­tory or meta­bolic dis­or­ders. A 62-year-old man ­with ­mitral ­valve insuf­fi­ciency ­with mod­erate ­aortic ­valve insuf­fi­ciency under­went oper­a­tion. Oper­a­tive find­ings ­were the rup­tured aneu­rysm of the ­mitral ­valve in asso­ci­a­tion ­with the cal­ci­fied quad­ri­cuspid ­aortic ­valve. ­There was no evi­dence of infec­tion in the ­mitral ­valve and the ­aortic ­valve. The ­mitral ­valve was ­repaired, the ­aortic ­valve ­replaced, and Cox ­Maze pro­ce­dure ­added. A ­rare com­bi­na­tion of ­mitral and ­aortic ­valve ­lesions ­without endo­car­ditis sug­gested ­that mechan­ical ­stress ­alone may ­induce ­mitral ­valve aneu­rysm.
