An Approach to Non-left Main Bifurcation Lesions: A Contemporary Review.

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Biomedical Engineering

Background:

• Coronary artery bifurcations are susceptible to atherosclerotic lesions due to low wall shear stress.
• Percutaneous treatment of bifurcation lesions presents significant challenges in complex coronary interventions.

Purpose of the Study:

• To emphasize the importance of bifurcation stenting philosophy.
• To present an individualized algorithmic approach for treating non-left main coronary bifurcation lesions.
• To discuss current scientific evidence on stenting techniques and intracoronary imaging for percutaneous coronary intervention.

Main Methods:

• Review of recent scientific evidence on bifurcation stenting strategies.
• Analysis of advantages and disadvantages of provisional side branch (SB) stenting versus upfront two-stent techniques.
• Evaluation of the role of intracoronary imaging in optimizing percutaneous coronary intervention outcomes.

Main Results:

• The choice between provisional SB and upfront two-stent strategies remains debated, especially for complex bifurcations with diseased side branches supplying critical myocardial territories.
• An individualized algorithmic approach is crucial for selecting the optimal treatment strategy.
• Intracoronary imaging plays a vital role in enhancing outcomes for bifurcation percutaneous coronary intervention.

Conclusions:

• Understanding bifurcation stenting philosophy is essential for effective treatment.
• An individualized approach, considering lesion complexity and myocardial territory, guides optimal strategy selection.
• Further research and application of intracoronary imaging can improve percutaneous coronary intervention outcomes in coronary artery bifurcations.
