title: Rheumatic mitral stenosis:cross-sectional echocardiographic analysis.
abstract: Twenty-one patients with rheumatic mitral stenosis diagnosed by both M-mode echocardiography and hemodynamic findings were subjected to detailed cross-sectional echocardiographic studies. The age of the patients ranged from 27 to 79 years with 76% females. Left ventricular longitudinal, short axis, and apical four-chamber cross-sectional echocardiographic views were obtained in each patient. Three predominant patterns of anterior mitral leaflet motion on left ventricular longitudinal view were observed and correlated with the severity of mitral stenosis: Pattern A (eight patients) with diastolic leaflet doming and restricted leaflet tip motion. Pattern B (eight patients) tip and body leaflet motion, and Pattern C (five patients) with the entire leaflet motion restricted. Mitral valve prolapse as a rebound phenomenon was observed in three patients who had marked leaflet doming in Pattern A and two had severe obstruction. The longitudinal cross-sectional echocardiography was superior to the apical view in assessing the diastolic doming motion of the anterior mitral leaflet. Thus, longitudinal cross-sectional echocardiographic analysis of the pliability and degree of doming of the anterior of the pliability and degree of doming of the anterior mitral leaflet is valuable in estimating the severity of mitral stenosis.
