Abstract
Background/Purpose
To evaluate the use of StentBoost® in the Tryton™ dedicated SideBranch Stent.
Methods & Results
The Tryton™ SideBranch Stent has been effectively used to manage complex bifurcations. However, the paucity of scaffolding in the proximal part of the stent makes it often difficult to visualise under standard radiographic imaging. We set out to evaluate whether by using an augmented radiographic imaging technique it was possible to aid visualisation of the stent. In particular the so call ‘wedding ring’ band which is crucial to the procedural success. We further evaluated whether it was possible to determine the apposition of the stent at the carina, its coverage and the ability to aid recrossing of the struts closest to the carina as well as the added radiation exposure.
Conclusions
StentBoost® was found to be invaluable to the procedural success of the Tryton™ deployment without adding any extra cost to the procedure and with only a 3.7% increase in radiation to the patient. It allowed enhanced visualisation in all cases to aid apposition, recrossing and coverage.

Background
Bifurcation lesions remain one of the challenges in Interventional Cardiology . The complexity of the disease at the bifurcation lends itself to a number of strategies to deal with this lesion subtype . Many of these have involved 2-stent strategies. However, the provisional T stenting strategy remains the recommended technique for most bifurcation lesions, with endorsement by several professional bodies including the European Bifurcation Club . (See Figs. 1– 5 .)
