Contemporary approaches to bifurcation stenting.

Area of Science:

• Interventional Cardiology
• Cardiovascular Medicine
• Medical Device Technology

Background:

• Bifurcation lesions in coronary arteries are frequent and linked to increased risks of major adverse cardiac events and restenosis post-percutaneous coronary intervention (PCI).
• Effective management necessitates a thorough understanding of lesion complexity, stent attributes, and available therapeutic strategies.

Purpose of the Study:

• To review and compare the evidence supporting provisional versus two-stent techniques for treating coronary artery bifurcation lesions.
• To delineate specific clinical scenarios and procedural techniques where a two-stent approach is indicated.

Main Methods:

• Systematic review of existing evidence on provisional and two-stent strategies for bifurcation PCI.
• Detailed description of procedural steps for two-stent techniques.
• Emphasis on critical elements including lesion preparation, intracoronary imaging, proximal optimization (POT), and kissing balloon inflation.

Main Results:

• Provisional stenting is identified as the preferred strategy for the majority of bifurcation lesions.
• Specific criteria and indications for employing a two-stent technique are outlined.
• The importance of meticulous procedural execution, including POT and kissing balloon, is highlighted for optimal outcomes.

Conclusions:

• Provisional stenting provides a suitable approach for most coronary artery bifurcation lesions.
• Two-stent techniques should be reserved for complex anatomies and specific challenging situations.
• Optimal outcomes in bifurcation PCI depend on careful lesion assessment and precise procedural techniques.
