Introduction: Coronary arteries and their branches travel along the surface of heart under epicardium. However a portion of these arteries may be embedded in the muscle called MB and the submerged coronary artery is called mural coronary artery. The knowledge about the number, length and depth of myocardial can help in identifying the people at risk. Coronary artery disease (CAD), also known as ischemic heart disease (IHD), is a group of diseases that includes: stable angina, unstable angina, myocardial infarction, and sudden cardiac death. With the above background, the present study has been undertaken to study the prevalence of myocardial bridges in the coronary arteries

Method and Material: The study had included the 50 adult human cadavers used for the routine dissection procedure. The coronary arteries were dissected from origin to termination. During their course MB were observed on the branches of coronary arteries. The morphological study of MBs which were found during dissection was done.

Results

1. 20 hearts showed MBs.

2. Out of 20 MBs, 12 were noticed on left coronary artery (LCA) and 8 were found on Right Coronary Artery (RCA

Conclusion

1. MBs are frequently seen in human hearts.

2. Left Anterior Descending Artery (LADA) was the commonest site to show MB
