T-Stenting Approach
Dissatisfaction with a single stent provisional strategy has led to the development of many dedicated two-stent strategies to treat bifurcation lesions (Table 1). The simplest approach is T-stenting, where a stent is placed in the side-branch precisely at the side-branch origin, after which a main vessel stent is placed, ˜jailing™ the side-branch. Efforts are then made to re-access the side-branch through the deployed stent in order to complete the procedure with kissing balloon inflations.
