| ==Overview==
| |
| A myocardial bridge or MB is defined as a segment of a major [[coronary artery|coronary]] [[epicardial]] [[artery]] that "tunnels" or passes intramurally through the [[myocardium]] beneath the muscle bridge during [[systole]].<ref name="pmid15764618">{{cite journal |author=Alegria JR, Herrmann J, Holmes DR, Lerman A, Rihal CS |title=Myocardial bridging |journal=[[European Heart Journal]] |volume=26 |issue=12 |pages=1159–68 |year=2005 |month=June |pmid=15764618 |doi=10.1093/eurheartj/ehi203 |url=http://eurheartj.oxfordjournals.org/cgi/pmidlookup?view=long&pmid=15764618 |accessdate=2012-07-01}}</ref><ref name="pmid12427660">{{cite journal |author=Möhlenkamp S, Hort W, Ge J, Erbel R |title=Update on myocardial bridging |journal=[[Circulation]] |volume=106 |issue=20 |pages=2616–22 |year=2002 |month=November |pmid=12427660 |doi= |url=http://circ.ahajournals.org/cgi/pmidlookup?view=long&pmid=12427660 |accessdate=2012-07-01}}</ref> Myocardial bridges are generally located in the distribution of the [[left anterior descending artery]] ([[LAD]]) and its [[diagonal branch]]es.

| ==Example==
| |
| Shown below are an animated image and two static images depicting myocardial bridge. Outlined with yellow in the image in the middle is the part of the coronary artery during diastole. This same part of the coronary artery is outlined in yellow in the image at the right during systole; note that this outlined part is narrowed compared to its shape during diastole.
