case_images: Considering the absence of cardiovascular risk factors, we performed a coronary CT scan (Figure 2) that confirmed the absence of abnormal coronary origin and showed a MB of the left anterior descending coronary artery (LAD) with an average depth of 2.3 mm and a length of 24 mm.
case_images: Coronary angiogram, caudal view. The black arrow shows the myocardial bridging on the left anterior descending coronary artery with a systolic compression of the lumen > 50%.
