Mitral valve prolapse is a common condition often associated with mitral regurgitation. Intuitively, one would expect a positive correlation between the severity of mitral valve prolapse and the associated regurgitation. This assumption is overturned by an unusual case of functional ventricularisation of the left atrium due to severe mitral valve ...
