What is unroofing of a myocardial bridge?

Myocardial bridge is a segment of coronary artery which tunnels through the myocardium. Myocardium is the technical term for heart muscle. Coronary arteries are blood vessels supplying oxygenated blood to the heart muscle. Myocardial bridges are usually an incidental finding on coronary angiography, the X-ray imaging of blood vessels after injecting radiocontrast medication. But occasionally myocardial bridge can cause chest pain and heart attack. Though most myocardial bridges are left alone, sometimes a stent is inserted in the blood vessel when there is recurrent chest pain not relieved by medications. Rarely some of them may be bypassed by an operation as well. But stents which are tiny metallic spring like material used to prevent blood vessel closure, may get fractured by the powerful contraction of a myocardial bridge. Bypass may also fail sometimes. Another option is unroofing of the myocardial bridge.
