Myocardial bridging (MB) is a common anatomical varient in which a segment of coronary artery takes an intramural path. Occasionally, it can result in symptomatic ischemia. We present four cases in which MB was treated with drug-eluting stents that subsequently fractured, leading to recurrent symptoms.
心肌桥（MB）是一种常见的解剖变异，其中一段冠状动脉走行于心肌内。偶尔，它可导致有症状的心肌缺血。我们报告4例采用药物洗脱支架治疗心肌桥，随后支架发生断裂，导致症状复发的病例。
