Rare Occurrence of Syncope and Nodal Rhythm Caused by Left Anterior Descending Myocardial Bridge

Conclusion

We describe a 59-year-old man with syncope and nodal rhythm due to a 9-mm mid-LAD myocardial bridge, marked by chest pain and troponin elevation. This rare presentation underscores the ischemic potential of myocardial bridging beyond angina, urging its consideration in unexplained syncope and arrhythmias. Tailored therapy with calcium channel blockers proved effective, supporting guideline-directed management. OCT and IVUS can help in evaluation of coronary muscle bridges and determine the correct treatment strategy.
