**2.4.6 The pattern of 'overturned mitral valve'**

The pattern of 'overturned mitral valve': this kind of mitral lesion resembles the mitral valve flail as general echocardiographic aspect, but in the 'overturned mitral valve' the chordae are not ruptured (Figure 8). There is only an excessive elongation of the chordae and an obvious prolapse of the mitral valve into the left atrium.

Fig. 8. Transthoracic echocardiography 4 chamber view, showing the obvious prolapse of the posterior mitral leaflet, due to the 'eversion' of the mitral valve. There is a loss of leaflet coaptation due to an excessive elongation of the mitral chordae (verified in the operating theatre).
