2 Figure 1 Mitral valve anatomy. Schematic drawings of true parachute mitral valve, with all chordae attached to a single papillary muscle (A); parachutelike asymmetric mitral valve, with chordae attached to two papillary muscles, one being elongated and displaced toward mitral valve annulus (B); and normal mitral valve, with chordae distributed equally between two distinct papillary muscles (C).
