Multidetector Computed Tomography Findings of Myocardial Bridge and Its Relationship With Coronary Calcification

Q: What was the study objective regarding myocardial bridge (MB)?

To evaluate the prevalence and anatomical characteristics of myocardial bridge using MDCT and to investigate its relationship with coronary calcification and atherosclerotic burden.

Q: How was coronary calcification quantified in the study?

Coronary calcification was quantified using the Agatson score.

Q: What did the results show about MB prevalence and common symptoms?

MB prevalence was 7.7% (542 patients). Patients with MB most commonly had atypical chest pain (76%) and stable angina (24%).

Q: How does MB relate to coronary calcification severity?

Significant calcification was found in 23% of MB patients, who had higher calcification scores, particularly when coronary artery stenosis exceeded 50%.

Multidetector computed tomography (MDCT) is used to quantify the prevalence and anatomical characteristics of myocardial bridge (MB) and to examine how MB relates to coronary artery calcification and overall atherosclerotic burden. A retrospective cohort of 7024 patients undergoing MDCT between 2010 and 2020 measures MB length and thickness and applies Agatson scoring for coronary calcification. Patients are stratified by coronary stenosis (<50% vs ≥50%).

Objectives: Tis study aimed to evaluate the prevalence and anatomical characteristics of myocardial bridge (MB) using multidetector computed tomography (MDCT) and to investigate its relationship with coronary artery calcifcation and atherosclerotic burden. Methods: We retrospectively analyzed 7024 patients who underwent MDCT for cardiac complaints between November 2010 and December 2020 . Te length and thickness of MBs were measured, and coronary calcifcation was quantifed using the Agatstonscore. Patients were categorized according to the degree of coronary stenosis (< 50% or ≥ 50%) to assess the association between MB and calcifcation severity. Results: Te prevalence of MB was 7.7%(542 patients) . Te most common complaints in patients with MB were atypical chest pain (76%) and stable angina (24%). MB was most commonly detected in the middle segment of the LAD artery (65.68%) . Mild atherosclerotic plaque (31%), moderate atherosclerotic plaque (13%), and severe atherosclerotic plaque and stenosis (5%) were present in 51% of patients with MB. Signifcant calcifcation was found in 23% of MB patients, who had higher calcifcation scores, particularly those with coronary artery stenosis greater than 50% . Conclusions: MDCT serves as an efective noninvasive method not only for detecting MB but also for evaluating concomitant coronary calcifcation and early atherosclerotic changes. Early identifcation of calcifcation in MB patients may guide individualized cardiovascular assessment, focusing on noninvasive imaging, risk factor control, and preventive therapy similar to standard protocols for atherosclerosis management.

In some cases, it may be associated with serious conditions such as ischemia, infarction, arrhythmia, angina, or sudden death [1] . Various methods such as multidetector computed tomography (MDCT) or coronary angiography (CAG) can be used for the detection of MB, or it may be identifed postmortem. According to Ishikawa et al., the prevalence of MB can be detected by MDCT in 3.5%–58%, by CAG in 0.4%–15.8%, or in 4.7%–60.0% of autopsy cases [2] . Altin et al. found a 1.1% incidence of MB among 5548 patients undergoing CAG, while Altin et al. reported a 6.42% incidence in cases undergoing MDCT [3, 4] . Te most common site of MB is the middle third of the left anterior descending (LAD) artery. More rarely, it can also be observed in the right coronary artery (RCA), frst and second diagonal arteries, ramus, and marginal branch arteries [5] . In this study, we aimed to investigate the anatomical structure of MB and the prevalence of its diferent localizations in coronary arteries. Additionally, we sought to 2 Cardiology R
