“…The lack of correlation between the type of vascularization and localization of myocardial bridges was confirmed in the studies of Bharambe and Arole (40). Ashraf and Nasr (38) came to the same conclusions and point out that 77.8% of myocardial bridges were on the left coronary artery, without a significant difference in regard to the type of vascularization, which is in accordance with the results of this study, where of a total 33 myocardial bridges, 25 (75.76%) were localized to the left coronary artery.…”

“…The results of this study have indicated that the incidence of arterial vascularization types is approximately same in the heart group with myocardial bridges as well as in the group without them, so it is established that there is no correlation between the presence of myocardial bridges and the type of arterial vascularization of the heart. Up to the same conclusion came Luis Erresto and his associates who investigated the Colombian population (37), as well as Ashraf and Nasr (38) among the Saudi population. However, these results are opposite to the results of Loukas and associates (39) who state that among the hearts with present myocardial bridges, the left type of vascularization is most common, in 66.6% of cases, while the right type is represented by only 24.6%.…”

“…The relation between the type of coronary circulation and the presence of myocardial bridges is rarely investigated and there is little data in the literature (37)(38)(39). The results of this study have indicated that the incidence of arterial vascularization types is approximately same in the heart group with myocardial bridges as well as in the group without them, so it is established that there is no correlation between the presence of myocardial bridges and the type of arterial vascularization of the heart.…”

Introduction: Myocardial bridges represent an anomaly of the coronary arteries' flow, which can be asymptomatic, or can lead to the coronary insufficiency and its clinical consequences. The aim of this research was to derermine whether there is a correlation between the type of arterial vascularization and presence and localization of the myocardial bridges. Material and Methods: As a material for this work, we used 45 human heart specimens from the Institute of Anatomy of the Medical Faculty in Sarajevo. At each heart, the type of arterial vascularization was determined, and in those specimens with myocardial bridges, the branch on which they were localized was recorded. Results: Out of total 45 human hearts, myocardial bridges were present at 24 (53.3%). One myocardial bridge was present in 16 hearts, two in 7 hearts and three in one heart. In the heart group with myocardial bridges, the incidence of right type of vascularization was 79.2%, and in the group without myocardial bridges 76.2%. The left type of vascularisation was least represented in both groups, with 9.5% in the heart group without bridges and 8.3% in the group with myocardial bridges present. Out of 33 detected myocardial bridges, 25 of them were on the left and 8 on the right coronary artery, so myocardial bridges are much more often localized on the branches of the left than the right coronary arteries, regardless of the type of arterial vascularization. Conclusion: There is no correlation of the type of arterial vascularization of the human hearts with the presence and localization of myocardial bridges.

The main objective of this article was to analyze prevalence data about myocardial bridging (MB) in published studies. To this purpose, we performed a meta-analysis of studies published in English literature that contained data about the prevalence of MB and its anatomical characteristics. The overall prevalence was 19% (CI: 17-21%); autopsy studies revealed an overall prevalence of 42% (CI: 30-55%), CT studies 22% (CI: 18-25%), and coronary angiography 6% (CI: 5-8%). Most bridges were located on the left anterior descending artery (82% overall, 63% on autopsy studies), had a mean thickness of 2.47 mm and a mean length of 19.3 mm. In conclusion, autopsy studies should be the gold standard in evaluating the actual prevalence of myocardial bridges, while in vivo high-resolution CT scanning should be preferred to coronary angiography studies.

“…It is difficult to say with certainty what characteristics of a bridged segment predispose it to being symptomatic. Length and depth have been proposed as important features, with segments that are at least 2–3 mm deep and 20–30 mm long contributing to more symptoms ((20), (71). Bridging is also seen very commonly in individuals with hypertrophic cardiomyopathy, but it is unclear if negative outcomes are related to the cardiomyopathy itself or the bridged segment.…”

Coronary Artery Anomalies: Benign Entities or Pathologic Findings?

Many cases of sudden, natural death have obvious gross or histologic pathology to which the death can be attributed fairly easily. Sometimes, though, one encounters a death in which an abnormal finding is identified, but there is some hesitancy in attributing the death to it as one may be unfamiliar with the significance of the finding or has encountered it many times before in cases where death was clearly due to something else. Coronary artery anomalies firmly fit into this category for many pathologists. Anomalous origin of the coronary arteries is an uncommon anomaly occurring in a fraction of a percent of individuals, so one may only encounter one or two deaths with this lesion in his/her career. Without past experiences to rely upon, one may be unsure about the severity of the lesion and inadvertently dismiss a significant anomaly or attribute death to a benign variant. Myocardial bridging is on the other end of the spectrum. This entity is seen so commonly that many consider it to be a normal variant and entirely benign and incidental. While this may be true in the majority of individuals, myocardial bridging may cause cardiac dysfunction in a small subset of people. This manuscript will review the anatomy and potential pathophysiology of these anomalies with the goal of aiding the pathologist in certifying deaths in which they are encountered.
