Objective: Myocardial bridging (MB) is a congenital anomaly in which an epicardial coronary artery courses intramyocardially. MB-related compression is often asymptomatic but can rarely cause sudden cardiac death, arrhythmia, or ischemia. This study aimed to investigate the prevalence, demographic characteristics, and gender differences of MB. Materials and Methods: A total of 2950 patients who underwent invasive coronary angiography (CA) were retrospectively evaluated. Clinical characteristics, biochemical/hematological parameters, and angiographic findings were compared between genders. Results: MB was identified in 119 (4%) patients, of whom 75 (63%) were males and 44 (37%) were females. The mean age of patients was 61.4±10.6 yr. Among patients with MB, 60.5% had hypertension, 31.9% had diabetes mellitus, 53.8% had coronary artery disease, and 47.9% were smokers. MB was most frequently detected in the mid segment of the left anterior descending artery (LAD) in 61 patients (51.3%). No significant gender differences were observed in MB length, vessel distribution, or compression rate. Conclusion: MB is not an uncommon finding during invasive CA in middle-aged patients. The prevalence was 4% in our study. The most common site was the mid segment of the LAD. No gender-based differences were observed in MB length, vessel distribution, or compression rate.
