Myocardial bridging: light in the tunnel

Abstract

Myocardial bridging is a congenital anomaly in which a segment of a coronary artery runs intramuscularly. Although traditionally considered as a benign condition, myocardial bridging may be associated with clinically important complications such as myocardial ischemia, acute coronary syndromes and sudden death. We report the case of a highly symptomatic 36 years old patient with a myocardial bridge in left anterior descending coronary artery in which surgical treatment was proposed. Previous to surgery a non invasive coronariography with cardiac CT was practised in order to define the anatomy.

Elevated troponin levels in previously healthy children: value of diagnostic modalities and the importance of a drug screen

“…18 There was one patient who had a myocardial bridge, which has been reported as a cause of myocardial injury. [19][20][21][22] The same patient tested positive for cannabis; the myocardial bridge may have been an incidental finding, or possibly myocardial ischaemia may have been exacerbated by drug use. 15 Magnetic resonance imaging was diagnostic of myocardial inflammation and demonstrated the origin and course of the coronary arteries.…”

Myocardial bridging on coronary CTA: An innocent bystander or a culprit in myocardial infarction?

“…44 The mainstay of surgical therapy is coronary artery bypass grafting to segments distal to the myocardial bridging to improve the blood flow to compromised areas, or surgical unroofing of the intramyocardial coronary segment (myotomy) to relieve the systolic compression and to directly correct the congenital anatomical defect. 84,85 Conclusions Myocardial bridging is a common anatomic variant on coronary CTA. The frequency of bridging on coronary CTA is higher than that reported for ICA, because of the strong reliance of the latter of the finding of systolic compression of the involved segment in establishing the diagnosis.…”
