Morphometric Analysis of Papillary Muscles in Both Ventricles of Hearts
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 3
Abstract
Objective: To measure the length and breadth and attachment of papillary muscles in both ventricles of human hearts. Introduction: The papillary muscles of heart are conical in projections into the respective chamber of myocardium covered by endocardium. Functionally the papillary muscles are important part of the respective valve complex. They prevent the cusps of a valve from being everted when ventricle contracts. Contraction of papillary muscle prevents backward flow of ventricular blood into the atria by bracing the atrioventricular valves. This is due to high pressure of blood flow through the ventricles. During this process over a period the papillary muscle fibers tend to undergo wear and tear and sometimes detach themselves from the ventricular walls. In many cases rupture of papillary muscle may be caused by a heart infarct and ventricular dysfunction and resulting in ischemia and a long term complication such as prolapse of atrioventricular valves. Materials & Methods: One hundred adult human hearts irrespective of age and sex were used for the present study after obtaining necessary clearances from the Institutional Review Board and Institutional Ethical Committee of VMKV Medical College Salem, Tamilnadu, India for conducting the study. Results: The origin of septal papillary muscle was found to be attached below the anteroposterior commissure in 2%, below the posteroseptal commissure in 15% and 83% origin from near the anteroseptal commissure of ventricle of the heart.In the present study the length of left posteromedial papillary muscle was longer than the anterolateral papillary muscle. The length ranged from 9.19 to 28.98 mm with a mean of 18.89 mm ± 4.28.In the present study the breadth of left anterolateral papillary muscle was higher than all other papillary muscles in both ventricles. The breadth ranged from 2.94 mm to 12.76 mm with a mean of 6.89 mm ± 1.95. Conclusion: The mean length of posterior papillary muscle of the left ventricle was 18.89mm ±4.3 longer than the right ventricle papillary muscles which was statistically significant (p=0.01) .The breadth of the anterior papillary muscle of the left ventricle was more than all other papillary muscles. So the morphometric measurements of papillary muscles which will provide ready guides for the operating surgeon. Running Title: Morphometry of papillary muscles
