We present a 74-year-old woman who underwent corrective annuloplasty for severe mitral regurgitation due to dilated cardiomyopathy. Postoperatively, congestive heart failure improved, with her New York Heart Association status changing from IV to II, although her cardiac functional improvement was minimal. Severe mitral regurgitation may be the indication for annuloplasty in symptomatic patients with dilated cardiomyopathy when cardiac transplantation is not indicated.
