Systolic 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...

The influence of saddle-shaped annuloplasty on leaflet curvature in patients with ischaemic mitral regurgitation.

OBJECTIVES Reports indicate that repair procedures for ischaemic mitral regurgitation (IMR) are less durable than previously thought. Repair failure has been shown to be stress related. Leaflet curvature is the major determinant of valve stress. Theoretical and animal experiments have shown that saddle-shaped annuloplasty optimizes leaflet curvature when compared with standard flat ring annulop...

Cardiac Myxoma Originating from the Anterior Mitral Valve Leaflet

Primary cardiac tumors are rare and myxoma is the most common tumor among them. Cardiac myxoma usually occurs in the left atrium. Myxoma originating from mitral valve is extremely rare. We report a case of mitral valve myxoma. The tumor originated from the anterior mitral valve leaflet. The tumor was completely removed and replacement of the mitral valve was not done.
