Abstract

The Tryton-Side Branch Stent™ (Tryton Medical, Inc., Newton, MA, USA) is a dedicated stent designed to provide complete carinal coverage of bifurcational lesions. After implantation of a 18 mm cobalt chromium Tryton stent from the left circumflex into the obtuse marginal branch, recrossing with an everolimus eluting Promus stent and final kissing balloon dilatation, optical coherence tomography (OCT) (LightLab Imaging Inc., Westford, MA, USA) was performed with a non-occlusive technique with motorized pullback (3 mm/s) during continuous pump injection of iso-osmolar contrast, in both LCx and OM1. OCT imaging showed good strut apposition at the level of the carina, with full coverage and no stent protrusion at the ostium of the side branch. Few malapposed struts were present in the proximal main vessel in the segment of stent superimposition, with a maximal separation from to the vessel wall of 160 μm. The implantation of the Tryton-Side Branch Stent™ allowed full coverage of the side branch ostium with uniform apposition of the stent struts at the level of the carina assessed by OCT.
