Coronary perforation during DES implantation for myocardial bridging can be successfully managed with a covered stent, and may not cause immediate hemodynamic instability if confined to the interventricular groove.
May support covered stent bailout for contained perforation in myocardial bridging; leaves open need for prospective data on durability and generalizability.
We successfully rescued a patient whose coronary artery perforated following implantation of a drug-eluting stent (DES), by deploying a stent-graft in symptomatic myocardial bridging. Our case demonstrated that coronary perforation could be handled without difficulty when perforated myocardial bridging is confined to the interventricular groove.
