Myocardial bridging is associated with coronary atherosclerosis in the segment proximal to the site of bridging

Cholesterol; is accused for the atherosclerosis proximal to myocardial bridging?

Myocardial bridging is associated with alteration in coronary vasoreactivity.

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...

Multiple myocardial bridge in a 59 year-old woman

Introduction: Myocardial bridging is a congenital condition in which a segment of a major epicardial coronary artery has an intra myocardial route. Myocardial bridging is usually confined to a single vessel and is typically the mid segment of the left anterior descending artery. Bridging may be associated with chest pain, myocardial infarction, and sudden cardiac death, or usually asymptomati...

surgery of symptomatic myocardial bridging

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,...

High wall shear stress proximal to myocardial bridging and atherosclerosis: intracoronary ultrasound and pressure measurements.

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...
