Covered stent implantation for calcified nodule to physically hinder its protrusion causing restenosis: a case report.

ABSTRACT:

Background

Calcified nodule (CN) is a phenotypic feature of calcified plaques which causes acute coronary syndrome (ACS). Recent studies reported that culprit lesions harboring CN has been shown to increase a risk of repeat revascularization after percutaneous coronary intervention (PCI) with the implantation of newer-generation drug-eluting stent (DES) or debulking device. Mechanistically, a re-protrusion of CN into the lumen has been considered as an important cause associated with repeat revascularization after PCI. These observations suggest the need for additional therapeutic approach to mitigate a risk of repeat revascularization at CN lesions. Here we report a case who received the implantation of one covered stent due to coronary artery perforation after stent implantation
