provisional stenting
Bifurcation intervention strategy involving main vessel stenting with side branch treatment only if significant compromise occurs.
Full Definition
A stepwise approach to coronary bifurcation intervention that prioritizes main vessel treatment while preserving side branch access for bailout intervention if needed. The strategy begins with main vessel stenting, followed by assessment of side branch flow and stenosis. Additional side branch intervention is performed only if significant compromise occurs, defined by flow reduction, severe stenosis, or clinical evidence of ischemia. This approach contrasts with upfront two-stent strategies and has become the preferred initial technique for most bifurcation lesions based on clinical trial evidence.
