Relapsing polychondritis is a multisystem disease characterized by recurrent inflammation of the cartilaginous tissue. Cardiovascular manifestations of relapsing polychondritis are rare but are the second most common cause of death in these patients. We report a case of relapsing polychondritis who underwent aortic valve replacement uneventfully but presented six months later with myocardial infarction due to bilateral coronary ostial stenosis.
