Summary: | Intramyocardial bridging (IMB) is a congenital anomaly characterized by the tunneling of a coronary artery segment through the myocardium, potentially leading to serious cardiac complications, such as myocardial ischemia, infarction, and sudden death, challenging the traditional view of it being benign. A case involving a 42-year-old man with a seven-day history of atypical chest pain highlights the significance of considering IMB in the differential diagnosis. Despite normal troponin levels, creatine kinase (CK), CK-MB, D-dimer, a negative drug screen, a normal ECG, and chest X-ray and no apparent issues on echocardiogram, left heart catheterization revealed IMB in the left anterior descending artery. This case underscores the necessity of including IMB in the differential diagnosis for chest pain, particularly in young males with familial cardiovascular disease history. While noninvasive imaging methods are useful for diagnosis, coronary angiography is the definitive diagnostic tool. Treatment primarily involves beta-blockers and calcium-channel blockers, with revascularization as a secondary option for those unresponsive to medication. |
