Abstract

The mitral valve is not only a plain heart valve, but a very complex structure, and as such, an important part of the left ventricular chamber (Fig. 1). Valvular annulus, valve leaflets, and chordae tendineae are connected to the left ventricular wall by papillary muscles. Muscle fibers originating from the atrioventricular annulus run towards the apex, and rise from there, radiating into the papillary muscles on the inner layer of the ventricular wall [3, 16]. Consequently, the papillary muscles are not only part of the mitral valve apparatus, but also are the connecting link between the mitral valve and the left ventricular wall.
