Coronary Myocardial Bridge and Coronary Plaques on MDCT

Myocardial bridging is a condition in which a segment of a coronary artery passes through the heart muscle instead of running on its surface. This study aims to determine the prevalence of coronary myocardial bridging and investigate its relationship with coronary atherosclerotic plaques using multidetector computed tomography coronary angiography (MDCT-CA). The study will include at least 50 patients referred for coronary CT angiography at Sohag University Hospital and New Sohag University Hospital. CT images will be evaluated to identify myocardial bridges, determine their location, measure their length and depth, and assess the presence, location, and characteristics of coronary atherosclerotic plaques. The findings will be analyzed to investigate the association between myocardial bridging and coronary atherosclerotic plaques.

Inclusion Criteria: * All patients referred to the Radiology Department of Sohag University Hospital and New Sohag University Hospital for coronary CT angiography. Exclusion Criteria: * Patients with contraindications to CT examination due to radiation-related risks. * Patients with known allergy to iodinated contrast media or impaired renal function (serum creatinine \> 1.5 mg/dL or estimated glomerular filtration rate \< 30 mL/min). * Patients with heart rate or rhythm incompatible with electrocardiographically gated scanning (heart rate \> 70 beats/min or uncontrolled atrial fibrillation). * Patients with an Agatston calcium score \> 400. * Uncooperative patients or those who do not provide informed consent
