Abstract
A case of double-orifice mitral valve (duplication of the mitral valve) in an 18 mo. old baby is presented. The valve showed significant regurgitation and was replaced with a No. 20 Lillehei-Kaster mitral prosthesis. The patient is kept on dipyridamole (Persantin) 10 mg/kg and aspirin 50 mg/kg daily to avoid postoperative thromboembolic complications. Valve replacement should be the treatment of choice in severe mitral regurgitation associated with double-orifice mitral valve.
