Apical three-chamber (long-axis) view and obvious SAM of the anterior leaflet of the mitral valve with LV outflow obstruction visualized. Note thick interventricular septum, elongated anterior (right on the screen towards the noncoronary cusp of the aortic valve) leaflet of the mitral valve. Also note during systole (when aortic valve is opened) anterior leaflet of the mitral valve is moving forward, touching thickened interventricular septum (SAM), which result in additional outflow obstruction. CMP, cardiomyopathy; SAM, systolic anterior motion.
