Isolated mitral regurgitation complicating relapsing polychondritis

Abstract

The reported incidence of mitral regurgitation in relapsing polychondritis ranges from 2 to 3% and is associated with aortic regurgitation. There are no reports that mitral regurgitation can be an isolated cardiac complication of relapsing polychondritis. This case report demonstrates that partial chordal rupture and consequent severe mitral regurgitation can be the only features of cardiac involvement in relapsing polychondritis.
