Coronary perforation due to sirolimus-eluting stent’s strut rupture with post-dilatation

Abstract

Coronary artery perforation is a rare and dangerous complication of percutaneous coronary intervention. Its consequences may range from minimal dye staining of the pericardial cavity to haemodynamic collapse, and it requires urgent treatment. Nearly half of cases occur due to the use of stiff and hydrophilic guidewires. Perforations due to stent deployment or strut rupture are seen more rarely, but have a more serious prognosis. We present a case of coronary perforation due to rupture of a sirolimus-eluting stent’s strut. The perforated site was occluded immediately with the implantion of two consecutive bare metal stents.
