Maze procedure and homograft replacement of a rheumatic mitral valve.

A 64-year-old woman presented with congestive heart failure due to severe mitral valve stenosis and chronic atrial fibrillation. A Maze III procedure was performed, and the mitral valve replaced with a mitral homograft. Postoperatively, the patient regained normal sinus rhythm, had trivial mitral regurgitation, regained her atrial transport function, and had improved myocardial function.
