title: Echocardiographic features of mitral regurgitation due to ankylosing spondylitis.
abstract: A report of echocardiographic features of an extension of "subaortic bump" producing mitral regurgitation in a patient with ankylosing spondylitis and left-sided bivalvular regurgitation is described for the first time. The anatomic and echocardiographic features of "subaortic bump," specifically found in patients with ankylosing spondylitis, have been previously reported. A review of the literature on ankylosing spondylitis and mitral regurgitation is discussed.
