Mitral annular calcification (MAC) is a chronic, progressive process characterized by calcium deposition on the mitral valve annulus. There is no current grading system to relay the severity of MAC. The primary purpose of this study was to investigate the extreme end of the severity spectrum in order to describe “exuberant mitral annular calcification”, and a retrospective chart review of all patients with exuberant mitral annulus calcification evaluated at Mayo Clinic Rochester between January 1996 and December 2014 was performed. This is the first study to define criteria of “exuberant mitral annular calcification”, emphasizing the importance of identifying the extreme degree of mitral annular calcification.
