Fundamentals of percutaneous coronary bifurcation interventions

Area of Science:

• Interventional Cardiology
• Vascular Biology

Background:

• Coronary bifurcation lesions (CBLs) represent a significant challenge in percutaneous coronary interventions, associated with suboptimal procedural and long-term results.
• The complexity of CBLs necessitates specialized stenting strategies beyond the default provisional technique.

Purpose of the Study:

• To review current and emerging techniques for managing complex coronary bifurcation lesions (CBLs).
• To discuss the role of intravascular imaging and controversial aspects of CBL treatment.

Main Methods:

• Review of contemporary percutaneous interventional techniques for CBLs.
• Discussion of elective double stenting (EDS) strategies, including the double kissing crush technique.
• Emphasis on the importance of intravascular imaging for strategy selection and outcome assessment.

Main Results:

• Provisional stenting is common, but EDS techniques are preferred for specific complex CBL subsets.
• The double kissing crush technique is effective but complex; newer EDS methods aim for improved stent scaffolding and reduced adverse events.
• Intravascular imaging is crucial for optimizing interventional strategies and evaluating results.

Conclusions:

• Managing complex coronary bifurcation lesions requires careful consideration of various stenting techniques.
• Elective double stenting (EDS) approaches, particularly newer methods, show promise for improving outcomes in complex CBLs.
• Intravascular imaging plays a vital role in guiding interventions and assessing results for coronary bifurcation lesions.
