Abstract

Myocardial bridging is a common anatomical anamoly characterized by muscle bridge on the epicardial artery, Myocardial bridges may compress the coronary vessel and compromise myocardial blood supply, it is considered to be associated with myocardial ischaemia, myocardial infarction, arrhythmias and even sudden death. Materials and methods: This observational prospective study, conducted in the department of Anatomy, Fathima Institute of Medical Sciences, Kadapa, India, from April 2019 to January 2022. Eighty cadaveric human hearts collected from preserved adult human cadaveric hearts, the epicardium and fat were removed carefully from the surface of the heart. The origin and the course of all the coronary arteries and their important branches were carefully delineated and studied. Results: Of the total 80 hearts dissected, 74 showed MB in at least one coronary artery or in one of its significant branches, of which 49(66.21%) were males and 25(33.78%) were females. Myocardial bridging were found to be more common in the major branches of Left Coronary Artery (LCA). Though almost all the major branches were involved left anterior descending artery was significantly more involved. The maximum length of myocardial bridge was 4.7 cm, originated on the left anterior descending artery. Conclusion: The precise knowledge on morphological properties and pathological effects of themyocardial bridging may provide valuable information to the clinicians and cardiothoracic surgeons in efficient management of coronary disease and other cardiac ailments.
