Human myocardial bridging is a normal anatomic variation in which a coronary artery is bridged by a short segment of myocardium. It can cause variable degrees of systolic obstruction. The majority of patients are asymptomatic. A wide variety of syndromes can occur, including myocardial infarction and sudden death. All patients with myocardial bridges have systolic artery compression, but it is ...

Myocardial bridging is a segment of coronary artery that runs intramurally through the myocardium. Though it is commonly seen in the anterior interventricular artery and less commonly in right coronary artery, it can cause limitation in the blood flow, which leads to myocardial ischaemia. Left dominance increases cardiac mortality because of association with the congenital bicuspid aortic valve...

Abstract Background Myocardial bridging (MB) is a congenital epicardial coronary abnormality, in which segment of the artery runs through myocardium, determining dynamic stenosis during systole. Whether MB can be responsible by itself for myocardial ischemia remains unclear. Thus, we aimed to evaluate whether related cause signs and symptoms ischemia. Methods We enrolled 41 consecutive patients...

Myocardial bridging with systolic compression of the left anterior descending coronary artery (LAD) may be associated with myocardial ischemia. In symptomatic myocardial bridging unresponsive to medical treatment, surgical unroofing of the left LAD can be performed. Little information is available about the long-term prognosis of patients with this coronary anomaly after the surgical unroofing,...

Muscle overlying the intramyocardial segment of an epicardial coronary artery, first mentioned by Reyman1 in 1737, is termed a myocardial bridge, and the artery coursing within the myocardium is called a tunneled artery (Figure 1). It is characterized by systolic compression of the tunneled segment, which remains clinically silent in the vast majority of cases. An in-depth analysis of autopsy s...

A previously healthy 26 year old woman who was exposed to smoke during a house fire developed acute anterior myocardial infarction complicated by ventricular fibrillation. Subsequent left ventriculography confirmed anterior infarction, but coronary arteriography was normal apart from myocardial bridging over a segment of the left anterior descending artery. The development of acute myocardial i...

We successfully rescued a patient whose coronary artery perforated following implantation of a drug-eluting stent (DES), by deploying a stent-graft in symptomatic myocardial bridging. Our case demonstrated that coronary perforation could be handled without difficulty when perforated myocardial bridging is confined to the interventricular groove.
