Percutaneous coronary intervention (PCI) for bifurcation lesions is challenging despite the use of many different techniques and strategies, and is a predictor of procedural, early and late adverse outcomes, even in this drug-eluting stent era. The current limitations of PCI for bifurcation lesions are due, in part, to the use of stents designed and refined for the treatment of lesions in straight coronary segments. This has led several groups to develop novel dedicated stents specifically designed to treat bifurcation lesions. Among them, the Tryton™ side-branch stent has several innovative features that provide complete stent coverage and uniform strut apposition at the bifurcation site with full expansion of the side-branch ostium. This device is a balloon-expandable cobalt-chromium thin-strut bare-metal stent that is designed to integrate with 'workhorse drug-eluting stents. Early clinical data are very encouraging, showing very low rates of neointimal proliferation (late loss at the branch site = 0.17 mm) and target lesion revascularization (1%). Dedicated bifurcation stents are an exciting new technology that may further simplify the management of bifurcation PCI, improving acute and long-term outcomes.
