provisional stenting strategy
Bifurcation intervention approach prioritizing main vessel stenting with conditional side branch treatment based on post-procedural assessment.
Full Definition
Provisional stenting strategy is the preferred approach for most coronary bifurcation lesions, involving initial stent deployment in the main vessel with side branch intervention only if significant compromise occurs. This technique begins with main vessel preparation and stenting, followed by assessment of side branch patency, flow, and stenosis severity. Side branch intervention is performed only if there is >75% stenosis, TIMI flow <3, or significant clinical symptoms. The strategy minimizes procedural complexity, reduces dual antiplatelet therapy duration, and maintains good long-term outcomes for most bifurcation lesions. Advanced techniques such as proximal optimization technique (POT) and final kissing balloon inflation may be incorporated to optimize results while maintaining the provisional approach philosophy.
