“…Using coronary angiography, they are detected in as little as 0.4-12% (23)(24)(25)(26). Using dissection method, myocardial bridges are detected in a significantly larger number, so that the frequency of 53.3% determined in this paper coincides with the results of other authors using the same method and reported a frequency of 34.5% (27), 54% (28), 56% (29) and 58% (30).…”

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 ventral merger of the atria represents the clearest case for a feature that is not shared by all birds, and that may occur only within Passeriformes and Psittaciformes. This feature has not been described previously to the best of our knowledge, and is different from the myocardial bridges that embrace coronary vessels in mammals (Polá cek, 1961;Van Nie & Vincent, 1989;Lee & Chen, 2015;Hostiuc, Negoi, Rusu, & Hostiuc, 2018). Given that the ventral merger was found in five out of five hearts of the Blackbird, it seems likely that it is a stable feature within a species even though it may exhibit much variation between species.…”

Mammals and birds acquired high performance hearts and endothermy during their independent evolution from amniotes with many sauropsid features. A literature review shows that the variation in atrial morphology is greater in mammals than in ectothermic sauropsids. We therefore hypothesized that the transition from ectothermy to endothermy was associated with greater variation in cardiac structure. We tested the hypothesis in 14 orders of birds by assessing the variation in 15 cardiac structures by macroscopic inspection and histology, with an emphasis on the atria as they have multiple features that lend themselves to quantification. We found bird hearts to have multiple features in common with ectothermic sauropsids (synapomorphies), such as the presence of three sinus horns. Convergent features were shared with crocodylians and mammals, such as the cranial offset of the left atrioventricular junction. Other convergent features, like the compact organization of the atrial walls, were shared with mammals only. Pacemaker myocardium, identified by Isl1 expression, was anatomically node‐like (Mallard), thickened (Chicken), or indistinct (Lesser redpoll, Jackdaw). Some features were distinctly avian, (autapomorphies) including the presence of a left atrial antechamber and the ventral merger of the left and right atrial auricles, which was found in some species of parrots and passerines. Most features, however, exhibited little variation. For instance, there were always three systemic veins and two pulmonary veins, whereas among mammals there are 2–3 and 1–7, respectively. Our findings suggest that the transition to high cardiac performance does not necessarily lead to a greater variation in cardiac structure.

“…Myocardial bridging (MB) is a congenital abnormality characterized by the presence of an intramural course of a coronary artery that can give rise to systolic flow disturbances. According to a recent published meta-analysis the overall prevalence of MB was 19%, in autopsy studies 42%, in CT studies 22% and coronary angiography studies 6% 37 . The authors concluded that autopsy studies are the gold standard in evaluating the prevalence of MB and that high-resolution CT scanning of coronary arteries should be preferred over coronary angiography studies.…”
