Un-Retrieved Deformed Biodegradable Polymer Coated Drug Eluting Stent after Percutaneous Coronary Intervention to Complete Occluded Right Coronary Artery: Patient at 8 Months Angiographic Follow-Up

Balloon rupture during stent deployment is rare, and can cause stent damage upon its retrieval. We described a case of inadequate drug-eluting stent expansion in a fibrotic and calcified mid right coronary artery lesion despite pre-treatment with high pressure balloon inflation, with rupture and entrapment of the balloon within the stent. Attempts of retrieval of the ruptured balloon caused severe deformity of the distal segment of the stent. The stent could not be crushed or retrieved, and was left in situ. Angiographic follow-up at 8 months time showed widely patent vessel.
