Isolated posterior mitral valve cleft: diagnosis by real-time three-dimensional transoesophageal echocardiography.

We report a case of an isolated cleft mitral valve with two clefts in the posterior leaflet. Our case adds to the few reports of posterior and multiple mitral valve clefts and, to our knowledge, is one of the first using real-time transoesophageal three-dimensional echocardiography for the assessment of isolated cleft mitral valve.
