In patients with myocardial bridging, the area within the bridge usually remains free from atherosclerotic disease. The case of a 47 year old man is described who had the rare combination of myocardial bridging with an atherosclerotic plaque within the area of bridging, which was detected with intravascular ultrasound but not with coronary angiography. The clinical history of the patient demons...

BACKGROUND Myocardial bridging is present when a segment of a major epicardial coronary artery runs intramurally through the myocardium. It usually has a benign prognosis, but in some cases myocardial ischemia, infarction and sudden cardiac death have been reported. We are here reporting a case of myocardial bridging which was complicated with recurrent chest pain and transient ST-segment eleva...

Myocardial bridging (MB) is an anatomical variation characterized by narrowing during systole of some of the epicardial coronary arterial segments running in the myocardium. It can be encountered in 0.5% to 16% of routine coronary angiographies [1]. Although it is considered as a benign anomaly, it may lead to such complications as myocardial ischemia, acute coronary syndromes, coronary spasm, ...

Introduction Myocardial bridging is congenital anomaly which usually has benign prognosis but there are also reports suggesting that it can be associated with ischemic clinical syndromes presenting with chest pain. Coronary computed tomography angiography is a well-established method for detecting myocardial bridging. However, clinical significance of this anomaly still remains unclear. Metho...

Extensive myocardial bridging in the left anterior descending coronary artery was found in a 46 year old survivor of sudden cardiac near-death. Positron emission tomography and dobutamine stress echocardiography revealed ischaemia in the myocardium distal to the bridging. Spasm was excluded as cause of the ischaemia by intracoronary infusion of acetylcholine. Further evaluation of the haemodyna...

Myocardial bridging (MB) is defined as a coronary artery that tunnels through the myocardium, under overlying muscle bridge. It almost exclusively affects left anterior descending (LAD), especially middle part (midLAD).

BACKGROUND Studies have shown that myocardial bridging may prevent coronary atherosclerosis and that the segment proximal to the bridge is often sclerosed. The underlying mechanism is still unknown. METHODS Intracoronary ultrasound and pressure measurements were performed in a patient with myocardial bridging in the left anterior descending coronary artery. A 3.5 F, 20 MHz probe was used to m...

BACKGROUND Shear stress alteration has been recognized as a predisposing factor for the impairment of endothelial function. Myocardial bridging is a congenital condition associated with alteration in shear stress, however, its impact upon vasoreactivity remains undetermined. METHODS AND RESULTS This was a case-control designed study with 29 patients with myocardial bridging and 58 patients wi...
