Aims: The left anterior descending artery is the most involved vessel in the myocardial bridging of the coronary arteries. Revascularization of the left anterior descending artery (LAD) is considered an essential component of coronary artery bypass grafting (CABG) procedures. This study aims to evaluate the correlation between angiographic views of the coronary artery and intraoperative findings of the left anterior descending artery myocardial bridge (LADMB). Methods: The records of patients who underwent the CABG procedure between January 2015 and October 2022 were reviewed retrospectively. A total of 349 patients who had LADMB on coronary angiography (CAG) images and/or intraoperatively were evaluated. Patients were divided into two groups. The CAG group (n=50) consisted of patients with angiographic LADMB, and the CABG group (n=40) consisted of patients with LADMB that was detected intraoperatively. The correlation between myocardial bridge signs of the LAD in CAG and intraoperative observations was investigated. Results: In the coronary angiography group, 50 patients had signs of depression on coronary angiography, of whom 35 had LADMB intraoperatively. In the CABG group, 40 patients were found to have a myocardial bridge intraoperatively, and 5 had normal CAG images. The prevalence of LADMB was 11.5%. The sensitivity of CAG was 87.5%, the specificity was 95.15%, the positive predictive value was 70%, and the negative predictive value was 98.32%. Conclusion: The myocardial bridge signs of the LAD on CAG correlate with intraoperative observations with high sensitivity and specificity.

Background The clinical relevance and anatomic characteristics of intracavitary coronary arteries coursing within the right ventricle (RV) are largely unknown. Objectives The aim of our study was to assess the clinical and computed tomographic characteristics of patients diagnosed with intracavitary coronary arteries coursing within RV (intra-RV coronaries). Methods Electronic records from a single high-volume cardiac center were retrospectively screened for the presence of intra-RV coronaries among consecutive patients who underwent coronary computed tomography angiography (coronary CTA) from 2008 to 2019. Results Overall, 31,748 coronary CTA reports were evaluated, and 17 subjects with intra-RV coronaries were identified. None of these patients was referred for subsequent invasive coronary angiography. One patient underwent coronary artery bypass grafting, 1 patient had a history of percutaneous coronary intervention, and 1 patient had a concomitant coronary anomaly: left circumflex coronary artery originating from the right coronary artery. All of the involved coronaries (n = 17) were the left anterior descending coronary arteries (LADs). Typical segmental coronary course within RV was along the border between free RV wall and interventricular septum (beneath interventricular groove), often within trabeculae carneae of the RV. Only the midsegment and distal segment of the LAD traversed within the RV. The mean ± SD distance from the aorta to the coronary entrance into the RV was 74.5 ± 17.1 mm, whereas the mean ± SD intra-RV coronary length was 25.1 ± 14.0 mm. Conclusions Intra-RV course of the coronaries in an adult CTA population is an infrequent anatomical variant involving LAD. It may require additional attention during interventional and surgical interventions.
