Introduction: Chordae tendineae are fibrous collagenous structures supporting the leaflets of atrioventricular valve. Chordae tendineae form one of the important components of atrio-ventricular valve complex.They convey the contraction of the papillary muscles to the valve and so prevent the latter’s eversion. Dysfunction of these subvalvular components of tricuspid valve isfrequent. Materials And Methods: The present work was done by dissecting 42 formalin fixed adult human hearts. The sex of human was not considered. The following observations were taken (a) types of chordae tendineae (b)number of chordae tendineae attached to each papillary muscle and their mode oforigin, insertion and distribution. Observations And Results: In present study, five different types of chordae tendineae were found i.e. rough zone, fan shaped, free edge, deep and basal. The average number of chordae tendineae arising from each papillary muscle were as follows-APM-5.07, PPM- 3.04 and SPM – 2.1.The average number of chordae tendineae inserted into each cusp was as follows –anterior cusp-5.64, posterior cusp-4.07, septal cusp -8.64 and at each commissure -0.9.Thus the average number of chordae attached to the tricuspid valve was 19.25. Conclusion: This knowledge may help cardiac surgeons during surgical procedures conducted for correction of valve defects.
