myocardial bridge

my·o·car·di·al bridge

a bridge of cardiac muscle fibers extending over the epicardial aspect of a coronary artery; this finding, in cases of sudden unexpected death, has led to speculation that cardiac contraction during exertion could constrict the coronary artery.

However, on review of his cardiac MRI scan, no myocardial bridge was found.
It has many firsts to its credit such as removing a myocardial bridge -- a congenital heart defect -- using robotic technology in 2017 and the UAE's first robotic hysterectomy last year.

Fractional flow reserve measurement is not reliable for assessing myocardial bridge patients
Among those patients, 5 out of 7 (71.43%) of them coincided with the myocardial bridge. In the patients who presented with coronary spasms, involved vessels in 4 out of 7 (57.1%) were the right coronary artery, 2 out of 7 (28.6%) were the left anterior descending artery, and 1 out of 7 (14.3%) was the circumflex artery.
Stenting of a myocardial bridge is still controversial due to high restenosis rates, potential plaque prolapse, and risk of stent fracture.
Thereafter, fatty tissue was removed and arterial blood vessels prepared by careful dissection with special reference to the presence of the myocardial bridges. If bridges were detected, their length and thickness were measured by the precise electronic caliper (Black & Decker, 0.00-155.00 mm, Landscheid), while the angle between the myocardial bridge fibre axis and other axis of the crossed blood vessel was measured by a goniometer.
Anomalies of the left coronary artery (LAD) in decreasing order of frequency included myocardial bridge 71(23.3 Percent), separate origin of LAD and circumflex from LSV (absent left main trunck) 58(19.02 Percent), circumflex arising from RSV with anomalous course 28(9.18 Percent), coronary ectasia/ aneurysm 23(7.54 Percent), fistula 14(4.5 Percent), LAD arising from RSV with anomalous course 3(0.98 Percent), LCA arising from RSV with anomalous course(retroaortic) 1(0.32 Percent) and single coronary artery 2(0.66 Percent).
This condition is also accompanied by a bunch of cardiac muscle fibers that passes over those vessels like a bridge and therefore was called myocardial bridge and mural coronary artery (MB-MCA).
Objectives: To determine the frequency of atheromatous coronary artery disease in patients with myocardial bridge.
Myocardial bridge. In this anomaly, a portion of the coronary artery that is normally epicardial traverses through the myocardium.
INTRODUCTION: Muscle overlying one segment of an epicardial coronary artery, first mentioned by Reyman in 1737[1] and Black in 1805,R3]is termed a myocardial bridge and the artery running within the myocardium is called a tunnelled artery.
