Percutaneous coronary intervention (PCI) for bifurcation lesions (BLs) is considered high risk due to increased procedural adverse events when compared to non-bifurcation lesion. Dedicated bifurcation stents, specifically designed to allow minimally traumatic implantation in the main vessel and/or side branch while providing adequate scaffolding of the side branch ostium may offer an advantage over utilization of conventional stents. Coronary perforation as a complication of PCI is a rare but potentially lethal complication that is associated with a high rate of morbidity. Coronary artery perforation during PCI has been reported repeatedly. To our best knowledge perforation in a BL, PCI with the Tryton Side-Branch Stent has not been reported. This case highlights that the Tryton to be an easy-to-use device in BLs, also operator should be careful, not too aggressive, their potential risks should be born in mind and a graft stent must be available in catheterization laboratory for emergencies.
