Core Tip
Core tip: Stenting the coronary segment with myocardial bridging is known to have increased risks of in-stent restenosis, stent fracture and coronary perforation. Myocardial bridging is also increasingly recognized to be pro-atherosclerotic and potentially involved in acute coronary syndrome, including ST elevation myocardial infarction (STEMI). The safety and efficacy of stenting the culprit lesion with overlying myocardial bridging in STEMI as primary reperfusion therapy has not been established. Here we present a case where plaque herniation or prolapse occurred after stenting a culprit lesion in STEMI, where overlying myocardial bridging was recognized by post-stenting intravascular ultrasound. The plaque herniation at the stented segment with myocardial bridging contributed to acute stent thrombosis which required a second layer of stent deployment. This case highlighted that plaque herniation or plaque prolapse after stenting a segment with myocardial bridging in STEMI is a potential etiology for acute stent failure, and emphasized the important role of intravascular ultrasound in primary percutaneous coronary intervention.
