Cinefluorographic analysis of mitral valve motion in intact clogs provided evidence that the motility of the valve cusps is restrained by tension exerted through the chordae tendineae throughout the cardiac cycle, except for the rapid filling phase. At the onset of ventricular systole, early contraction of the papillary muscles may play an important role in approximating the mitral valve cusps. During ventricular ejection, the mitral cusps and valve ring move toward the apex of the heart… CONTINUE READING
