Abstract:
M-mode echocardiograms were recorded in 268 apparently healthy young male adults and the mitral valve motion during systole was analyzed. In 149 cases( 55.6%) out of 268 the predominant echo of mitral valve closure(CD line) was recorded as smooth line moving slowly anteriorly, in 48 cases(17.9%) the CD line showed an abrupt transient posterior motion during early systole, in 24 cases(9.0%) there were multiple additional echoes posterior to the CD line, 17 cases(6.3%) the mitral valve closure was recorded as pansystolic anteriorly concave echo deviating less than 2 mm from a drawn CD line, and 10 cases(3.7%) as curvilinear and anteriorly convex echo deviating from a drawn CD line. In the remaining 20 cases(7.5%), the mitral valve closure was recorded as pansystolic anteriorly concave echo deviating more than 2 mm from a drawn CD line, which was categorized to have mitral valve prolapse in the current study. However, there were no significant differneces in various echocardiographic dimensions of the heart and the aorta between those with and without mitral valve prolapse.
