Background & Objective: Aim of present study was morphological and morphometric observation of papillary muscles of tricuspid valve of human heart. Methodology: This study was carried out in 36 human (24 males and 12 females) heart from adult cadavers, which were dissected according to standard technique. All papillary muscles were observed for their shapes, numbers and dimensions in centimeters. Data were tabulated and statistical comparison were done using “chi square†and “z†test. Results: The average length of anterior, posterior and septal papillary muscle was 1.42 ± 0.29 cm, 0.94 ± 0.23 cm and 0.18 ± 0.08 cm while average breadth of anterior, posterior and septal papillary muscle was 0.41± 0.12 cm, 0.29± 0.09 cm and 0.11± 0.01 cm respectively. The anterior papillary muscles presented 1 head in 27.78% and 2 heads in 25%, while posterior papillary muscles presented 1 head in 27.78% and 2 heads in 25%. All the septal papillary muscles presented with 1 head. Single anterior papillary muscle was found to be 97.22% while posterior papillary muscle was found to be single in 72.28% and double in 27.78. Septal papillary muscle was found to be single in 25% cases and absent in 38.89% cases. Conclusion: Data obtained from this study might be helpful for reparative surgical procedures of tricuspid valve.
