Acute myocardial infarction caused by myocardial bridging alone confirmed by using intravascular ultrasonography

摘要

Dear Editor: Although the underlying pathogenesis of acute myocardial infarction (AMI) caused by myocardial bridging (MB) is not fully understood, high shear stress that induces endothelial dysfunction or damage that leads to thrombus formation has been mainly consid-ered. We report a case of AMI due to MB confirmed in a series of angiographic examinations, including intra-vascular ultrasonography (IVUS). Our data may pro-vide credible evidence that supports this hypothesis.
