[Necropsy study of the mitral valve transected according to five echocardiographic planes].
OBJECTIVE
To study, in anatomic specimens, the regions of the mitral valve transected by the parasternal long axis, the apical 5 chamber, the apical 4 chamber, the apical 2 chamber and the left ventricle apical long axis echocardiographic views.


METHODS
15 patients' hearts, after fixation through intra-ventricular injection of formalin, were cut according to the five above referred echocardiographic views.


RESULTS
Only the apical 5 chamber view studied adequately the most anterior regions of both mitral cusps. The apical 4 chamber and the parasternal long axis views examine the most posterior segments of the mitral valve. Heart sections made according to the apical 2 chamber view are not adequate to study both cusps on a anatomo-pathologic view. The left ventricle apical long axis is the one which better defines the length of both cusps.


CONCLUSIONS
Its necessary to know precisely the regions of the mitral valve sectioned by different longitudinal echocardiographic views in order to visualize through that method localized mitral valve prolapse.
