Previously reported cases of uni\u2010leaflet mitral valve were primarily related to absence or dysplasia of certain leaflets. We present a case here with mitral leaflets that were not divided into anterior and posterior as usual, but developed as an integral structure instead, which is different from previously documented cases of uni\u2010leaflet mitral valves. Real time three\u2010dimensional echocardiography (<jats:styled-content style=\"fixed-case\">RT<\/jats:styled-content>3<jats:styled-content style=\"fixed-case\">DE<\/jats:styled-content>) provides a visual presentation of the abnormal mitral structure which was confirmed by surgical operation.
