Myocardial Bridging (MB) is a benign condition that may be considered as a possible cause of ischaemic cardiopathy up to myocardial infarction. The authors describe the autopsy case of an MB of circumflex artery in a person with a myocardial infarction of the posterior wall of the left ventricle. In this case, the chronic ischemic heart disease can be explained by the congenital anomaly and in the literature there is scientific evidence to support the thesis. The MB is a benign condition that in combination with other risk factors can cause ischemic heart disease.
