Background: - The myocardial bridges are the myocardium overlying coronary arteries. The coronary arteries may dip into the myocardium for varying lengths and then reappears on the heart’s surface. Aims: The present study is aimed at studying the presence of myocardial bridges over coronary arteries and their branches by dissection method. Material and Methods: - A total of 50 adult hearts procured from dead bodies from the Mortuary of the Department of Forensic Medicine & Toxicology, CSM Medical University, Lucknow were included in this study irrespective of sex. The hearts were meticulously dissected along both the coronary arteries and the presence and location of myocardial bridges was noted along with the part of the artery and/or its branch it was crossing. Results: - The overall prevalence of myocardial bridging was found to be 42%. They were mostly seen over the left anterior descending coronary artery. In maximum cases, they were seen over the middle 3rd of the left anterior descending coronary artery. The reported incidence of myocardial bridges varies 5-58%. Conclusion: - They may be associated with a wide range of clinical problems, including acute coronary syndromes and arrhythmias. The contraction of the myocardial bridge may result in vessel compression and myocardial ischaemia.
