Morphological determinants of echocardiographic patterns of mitral valve systolic anterior motion in obstructive hypertrophic cardiomyopathy.
BACKGROUND The morphological determinants of mitral valve systolic anterior motion (SAM) and obstruction to left ventricular outflow in patients within the broad clinical spectrum of hypertrophic cardiomyopathy (HCM) are not completely understood, particularly the contribution of mitral leaflet length and size. METHODS AND RESULTS To clarify this issue, mitral valve specimens from 43 patients...

متن کاملSystolic anterior motion of the mitral valve.
APPEARANCE Appearance: Systolic anterior motion of the mitral valve (SAM) is a paradoxical motion of the anterior, and occasionally posterior, mitral valve leaflet towards the left ventricular outflow tract (LVOT) during systole (Fig. 1 and see Videos, Supplemental Digital Content 1 and 2, which demonstrate characteristic SAM with subaortic stenosis and mitral regurgitation on cine steady state...

متن کاملConservative approach to mitral valve replacement in hypertrophic cardiomyopathy with systolic anterior motion - a case report.
The authors report the case of a 60-year-old patient with hypertrophic cardiomyopathy (HCM), systolic anterior motion (SAM), and high gradient in the left ventricular outflow tract (LVOT) who underwent surgical treatment. During the surgery, myomectomy of the septum was performed using the Morrow method: despite the persisting SAM and increased LVOT gradients, the mitral valve was not replaced....
