“…Its severity was observed to be fatal with increase in age, co-morbidities, and inactive life style. Such disturbance of blood flow to the rest of the myocardium mainly occurs during systole and is resolved in the diastolic phase (9). This transient hypoperfusion was noted to be the main cause for all the cardiac related issued due to MB.…”

“…With the advancement of newer diagnostic modalities and techniques such as fractional flow reserve (FFR), intracoronary Doppler, intravascular ultrasound (IVUS), and coronary computed tomographic angiography (CCTA) have enabled the anatomic and physiologic evaluation of the coronary artery, systolic compression, and pathological effects on coronary flow in detail (3,7). To be precise, the encasement of coronary arteries by a myocardium tissue is referred as "myocardial bridging" and the artery running within the myocardium is referred to as a "tunnelled artery" (3,(8)(9)(10)(11)(12)(13)(14). The prevalence range was largely varied and reported between 0.004% to ~85% and noted mostly on coronary angiography and autopsy (9,13).…”

The pathophysiological mechanisms leading to MB include Venturi-like effect, branch steal mechanism, accelerated atherosclerosis, and supply demand mismatch, etc.…”

Objective: Myocardial bridging (MB) is an asymptomatic, benign, and congenital coronary anomaly with several possible manifestations. MB is formed by a segment of a coronary artery taking an intra-myocardial course. As of date, huge knowledge gap exists in the literature in terms of MB and its associated complications. Methods: This single-centre, observational, non-randomised study was conducted over a period of 20 months to identify the rare anomalies such as MB using coronary angiograms. Results: Eight of 400 cases screened have been found to have MB bridging in mid left anterior descending artery (LAD) segment. The male to female ratio was 7:1 all within an age range of 24 years to 45 years. Most of the patients were asymptomatic with no history of drug usage (6/8) and family history (3/8) of coronary disorders. In symptomatic cases, the most common presenting symptoms were observed to be typical chest pain, dyspnea, nausea, light-headedness, or headaches, diaphoresis, and tachycardia. In most of the patients, MB showed systolic shortening with resultant flow limitation on coronary angiography. The segments were reported to be 1 mm to 10 mm in size and traversed 1 cm to 3 cm length. All the patients were treated symptomatically and were kept on follow-up. No mortality was observed in any case with MB. Conclusion: Even though MB is a benign condition, but its vast array of related complications was reported to be life threatening and require prompt diagnosis and treatment. This study focus on such MB related risks by highlighting the importance of differential diagnosis and the treatment followed by to avoid all possible complications in all those patients presenting with possible signs and symptoms.

“…Calcium channel blockers provide similar hemodynamic effects as beta-blockers and can be used as alternative to beta-blockers in symptomatic patients who cannot tolerate beta-blockers due to active bronchospasm or other contraindications to use of beta-blockers, and the Nitrates worsen the coronary compression in MB patients. 5 , 19 …”

Myocardial bridge (MB) is a congenital coronary anomaly in which a portion of the coronary artery courses intramyocardium instead of the normal trajectory on the epicardial surface. We report a case study with a 44-year-old man from Faryab Province in Afghanistan who presented chest pain and dizziness while suffering a common cold. After full investigation, the patient underwent coronary angiography which showed a myocardial bridge at the middle portion of the left anterior descending artery (LAD) with a significant stenosis causing ischemia. We treated the patient with a calcium channel blocker as initial treatment. The patient tolerated the medication well and remained asymptomatic during two years follow-up.

“…Myocardial bridging is a rare anatomical variant in the coronary artery potentially leading to myocardial ischemia, left ventricular dysfunction, cardiac arrhythmia, and even sudden cardiac deaths [1][2][3][4]. Surprisingly, a higher prevalence is revealed in autopsy compared to coronary angiogram [5].…”

Myocardial bridging is a rare anatomical variant that can lead to detrimental cardiac consequences when undiagnosed and untreated. This rare variant can induce anginal-type symptoms due to disrupted blood flow to the myocardium during systole. The patients presented in this report of two cases had previously undiagnosed myocardial bridging of the left anterior descending artery, however clinically, they presented quite differently. Here we present two cases discussing the course of diagnosis and treatment of myocardial bridging of these two patients. The goal of this case report is to highlight the significant cardiovascular injuries that can be a result of undiagnosed myocardial bridging.
