Sudden early diastolic anterior movement of the septum in endomyocardial fibrosis.

Rheumatic heart disease and endomyocardial fibrosis: Distinguishing the etiology of mitral regurgitation in low-resourced areas

“…(33,37) On M-mode the interventricular septum motion assuming an M-shaped movement, as a result of rapid anterior movement in early diastole. (38) In early stages of EMF spontaneous contrast and ventricular thrombi may be observed in a normally contracting left ventricle. (33) Ventricular obliteration -consisting in partial or complete exclusion of a portion of the ventricle from the circulation -affects both the apex and the recesses of the posterior mitral valve leaflet excluding these parts from the ventricular cavity.…”

Role of Echocardiography in Research into Neglected Cardiovascular Diseases in Sub-Saharan Africa

“…Several authors from different parts of the world have described the clinical and echocardiographic findings in EMF (Acquatella et al, 1979;Gonzalez-Lavin et al, 1982;Vijayaraghavan et al, 1983;Okereke et al, 1991;Rashwan et al,1995), and more recently there have been attempts to use this technique for understanding its epidemiology as well define prognostic criteria prior to surgery (Mady et al, 2004).…”

“…On M-mode the interventricular septum has a rapid anterior movement in early diastole (Acquatella et al, 1979) assuming an M-shaped movement. In some patients the septal motion may be reversed (paradoxical septal movement).…”
