title: Metal fatigue in myocardial bridges: stent fracture limits the efficacy of drug-eluting stents.
abstract: 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.
