Coronary perforation in PCI occurs in 0.2–0.3% of cases, depending on PCI complexity, and is associated with increased mortality risk [1, 2]. For grading of coronary perforation, the Ellis classification is most commonly used . Implantation of a covered stent is one of the therapeutic options, though with an increased risk of in-stent thrombosis and restenosis .
In our patient, a covered stent was subsequently implanted to seal the perforation (Fig. 1b). Although the clinical course was complicated by recurrent episodes of mild pericarditis, our patient could be discharged five days after the PCI. This case emphasises that stenting of intra-mural coronary arteries, even when partially intramural, should be discouraged.
