The Tryton-Side Branch Stent (Tryton Medical, Newton, Massachusetts) is 1 dedicated bifurcation system, designed to be implanted in the side branch (SB) along with placement of a standard drug-eluting stent (DES) in the main vessel (1). The procedure is completed by a final kissing balloon dilation of both stents, which requires crossing of the Tryton-stented SB through the main branch stent struts (Fig. 1). Motorized fractional flow reserve (FFR) pullback (at 1 mm/s) during hyperemia was used to allocate intracoronary pressure gradient variations, allow coregistration with anatomical, optical coherence tomography (OCT)-derived imaging, and verify optimal morphological and functional result of the dilation of the bifurcation stenoses (Fig. 2).
