Morphological Study on Myocardial Bridges and Its Clinical Significance
نویسندگان
چکیده
Myocardial bridging is recognized as an anatomical variation of the human coronary circulation in which an epicardial artery lies in the myocardium for part of its course. Thus, the vessel is ‘bridged’ by myocardium. The present study is aimed to studying presence of myocardial bridges over coronary arteries and their branches by dissection method. A total of 50 adult human hearts (irrespective of sex) were collected from Department Of Anatomy, Govt. Medical College, Surat. The hearts were dissected along both the coronary arteries and its branches and presence, location, and length of the bridges were noted. The overall prevalence of myocardial bridges was found to be 52%. There was trifurcation of left coronary artery(LCA) in 2 specimens(4%).The left anterior descending branch of the left coronary artery has been reported as the most common site of myocardial bridges (46.15%) but other locations have been reported.The maximum length of myocardial bridge was 45 mm over posterior interventricular branch of right coronary artery. The purpose of this study was to provide more definitive information on the vessels with myocardial bridges and the length of bridge segment. Myocardial Bridge (MB) on the coronary artery is associated with ischemic heart disease and cardiomyopathy.

BACKGROUND Myocardial bridges represent a hotly debated research topic. Myocardial bridges are considered to be a vascular heart variation due to its intermittent or enduring reducing of the arterial lumen, with a possible ischemic effect. METHODS 154 hearts were studied, having been extracted as fresh autopsy material. Coronary arteries were injected with synthetic resin and cleaned by extra...

Since its first description in 1922, the incidence and pathophysiologic significance of myocardial bridges has remained controversial due to the relatively small size and retrospective design of most studies. We assessed the incidence and clinical consequence of myocardial bridges in 2547 patients undergoing coronary arteriography over a 16-month period at our medical center. Of the 511 patient...

Myocardial bridge is a benign congenital anomaly in which a segment of major epicardial coronary arteries descends into the myocardium for a variable distance. Myocardial bridge is most often single and located in the middle part of the left anterior descending artery. The presence of more than one myocardial bridge in coronary arteries is very rare. We present a patient with more than one myoc...

OBJECTIVE To assess the arrangement of myocardial bridges. DESIGN A necropsy study of 90 consecutive hearts (56 male, 34 female). RESULTS Myocardial bridges, either single or multiple, were seen in 50 (55.6%) of the 90 hearts. The left anterior descending artery was the most commonly affected artery. Thirty five of the 50 hearts which contained in total 41 muscle bridges were dissected furt...

Background: It is assumed giving oxygen to patients with acute myocardial infraction may increase the oxygenation of the ischemic tissue; however, the usefulness of oxygen in these patients has become a challenging topic. Thus, the present study aimed to determine the effect of oxygen inhalation on cardiac biomarkers in patients with acute myocardial infarction. Methods: This randomized cli...
