Abstract

Introduction: - The human heart comprises four chambers with openings to facilitate blood inflow
and outflow. These openings are safeguarded by valves that ensure planned and controlled blood
flow. The annulus, the periphery where the valves are attached, plays a crucial role in this process.
Two atrioventricular valves, tricuspid and mitral (bicuspid), are named after the number of cusps they
possess and are located between the atria and chambers on both sides. The pulmonary valve regulates
blood flow in the pulmonary trunk while the aortic valve regulates the flow through the aorta.
Materials and Methods: - The study took place in the anatomy department of Index Medical
College Indore, Madhya Pradesh , where 45 formalin-fixed heart specimens were examined. The
hearts were dissected, allowing for visual examination of the interior to identify the tricuspid and
bicuspid valves. Results:- Our current study observed that the annular Circumference of the
Tricuspid valve ranges from 46.09 to 131.92 mm, with a mean of 90.28±17.86. While annular
Circumference of the bicuspid Valve ranges from 64.18-128.15 mm with a mean of 84.11 ±14.25
Conclusion:- A thorough understanding of the anatomical features of the atrioventricular valve can
enhance our comprehension of its structure and function. This knowledge can play a key role in
improving the outcomes of conservative treatments and facilitating a return to normal anatomical and
functional states
