Myocardial bridging is a congenital anomaly in which a segment of a coronary artery takes a “tunneled” intramuscular course under a “bridge” of overlying myocardium. This may cause vessel compression in systole, resulting in haemodynamic changes that may be associated with angina, myocardial ischaemia, acute coronary syndrome, left ventricular dysfunction, arrhythmias, and even sudden cardiac death [1]. Myocardial bridging, first described anatomically by Reyman in 1737 [2] is a congenital variant of a coronary artery in which a portion of an epicardial coronary artery (most...

CTA was performed using prospective electrocardiogram gating on 128-slice, dual-source CT scanner, (Somatom Definition Flash, Syngo CT 2011A, Erlangen, Germany). Patients were positioned appropriately in supine position, ECG leads were attached, and large intravenous access (18 gauge) was established for the injection of the contrast agent (Omnipaque 350 or Visispaque 320) followed by normal saline at a rate of 6ml/s. Most of the patients were pre-medicated with short-acting nitroglycerin sublingual spray and the intravenous beta-blocker (5-15mg of intravenous metoprolol) given only for the patient with...

2999 CTA’s were performed with 70 cases of myocardial bridging identified (incidence 2.4%), in patients with an age range of 29-82 years and an average age of 49.5 years (median). There were 52 males (74%) and 18 females (26%). 60 cases had myocardial bridging involving the LAD only, 5 cases involved the right coronary artery (RCA) only, 2 cases involved the LAD and the obtuse marginal (OM) artery, and 1 involved the Ramus Intermedium (RI) only. 2 patients had a malignant course of the RCA...

Myocardial bridges were an uncommon finding with the majority being found in male patients, with 86% of cases involving the LAD. RCA bridges seemed to be more common in women and interestingly we had 2 malignant course RCA’s in the bridging patients. MDCT coronary angiography is accepted as a reliable non-invasive method for the diagnosis of myocardial bridging because MDCT directly depicts the length and depth of the tunneled segment, along with its degree of compression during systole. MDCT is also efficient in showing the...
