Abstract

Background:

The presents study focused to document the discrepancies among an anterior (APM), posterior (PPM) and septal (SPM) papillary muscles in the right ventricle.

Methods:

We studied apparently normal post-mortem heart (n=60) and represent grouped as “group A” (n=41, 68.33%) and “group B” (n=19, 31.66%) based on male and female respectively. Age of the samples of heart, ranging from 20-70 years, collected from the department of forensic Medicine of DMC and SSMC. Windows, SPSS 22.0 version was used for the statistical analysis of this study. The Unpaired t- test was done to observe the importance between two groups in relation to sex.

Results:

Single number of APM was very frequent in both groups (M: F = 85%:68%) whereas double number of PPM were identified more, about 53% in both genders. (M: F = 85%:68%). Remarkably abundant pattern of SPM were 3 in numbers (M: F = 47%:68%). The highest number of papillary muscles discovered, were 4 in numbers which belonged to PPM (10%) and SPM (11%) for “group A” and “group B” respectively. The unpaired student’s t test was found statistically insignificant.

Conclusion:

The present study will give us a baseline data concerning variations of amount papillary muscles of the right ventricle in Bangladeshi population of both gender. The present research will offer a definite outlay for management & provides supplementary information to physicians, cardiologists, anatomists, physiologists and forensic inspectors who will serve them in determining the diagnosis and management of different cardiac diseases involving papillary muscles.
