What is the common bifurcation stenting strategy?

• A. Always deploy two stents in bifurcation lesions
• B. Use drug-coated balloon only
• C. Provisional one-stent strategy with a backup plan for a second stent; kissing balloon technique if two stents are deployed
• D. Do not treat bifurcation lesions with stents

Answer: (C)

In bifurcation stenting, the most commonly used approach is a provisional one-stent strategy: treat the main vessel first and have a plan to address the side branch if needed. This means you start by placing a single stent in the main branch and then carefully evaluate the side branch after that step. If the side branch remains patent with no significant narrowing, dissection, or flow limitation, you typically don’t put a second stent. The backup plan comes into play when the side branch shows significant residual disease or compromise after main-vessel stenting. If the situation requires it and you end up deploying two stents, you perform a kissing balloon inflation. This means you inflate both stents at the bifurcation, simultaneously, to optimize the ostial openings, align the stents nicely at the carina, and ensure good flow into both branches. This technique helps prevent ostial restenosis and ensures that the bifurcation geometry is preserved. Why the other approaches aren’t the standard: deploying two stents in every bifurcation increases procedural complexity, cost, and risk without proven benefit in most cases. A drug-coated balloon–only approach is not the typical strategy for bifurcation stenting, and simply not treating bifurcation lesions with stents isn’t appropriate for lesions that require revascularization.
