A coronary artery<unk>  refers to a split or a tear in the wall of the artery which compresses or compromises the lumen of the artery reducing blood flow. Coronary artery<unk>  occurs rarely in the absence of percutaneous coronary intervention (PCI). The risk of reduced anterograde flow and lumen narrowing is a relatively (< 3%) uncommon complication of PCI. Significant residual<unk> s are present in approximately 1.7 % of patients undergoing PCI. Intracoronary stent placement is used to stabilize the<unk> .
