Key result
RT-3DE visualizes a rare uni-leaflet mitral valve confirmed on surgical inspection.
Why the study?
Numerical abnormalities of mitral leaflets represent a special entity in congenital mitral malformations, with previously reported uni-leaflet mitral valves related to absence or dysplasia of leaflets.
Case Report (n=1)
RT3DE is useful for visualizing rare congenital mitral valve malformations such as an integral uni-leaflet structure.
RT3DE may aid visualization of rare mitral anomalies in select cases; leaves broader adoption open pending prospective data.
Numerical abnormalities of mitral leaflets is a special entity in congenital mitral malformations. Previously reported cases of uni-leaflet 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-leaflet mitral valves. Real time three-dimensional echocardiography (RT3DE) provides a visual presentation of the abnormal mitral structure which was confirmed by surgical operation. To the best of our knowledge, this unusual form of uni-leaflet mitral valve has not been reported yet.

Zhang et al. (2017) conducted a case report in Congenital uni-leaflet mitral valve with severe stenosis (n=1). Real time three-dimensional echocardiography (RT3DE) was evaluated on Visual presentation and surgical confirmation of abnormal mitral structure. Real time three-dimensional echocardiography successfully visualized an unusual integral uni-leaflet mitral valve structure, which was subsequently confirmed by surgical operation.
