Drug-Coated Balloons in Coronary Bifurcation Disease: A State-of-the-Art Review

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Medicine

Background:

• Coronary artery bifurcation lesions present unique challenges for percutaneous coronary intervention (PCI).
• Traditional approaches like provisional stenting or two-stent techniques carry risks of side branch compromise and procedural complexity.
• Target lesion failure is a significant concern in managing these complex anatomies.

Purpose of the Study:

• To review the current evidence on drug-coated balloons (DCBs) for coronary bifurcation lesions.
• To evaluate the evolving role of DCBs in PCI strategies for bifurcations.
• To identify patient- and lesion-specific factors influencing the choice of DCB treatment.

Main Methods:

• Systematic review of existing literature on DCB use in coronary bifurcations.
• Analysis of clinical trial data and observational studies.
• Synthesis of expert opinions and guidelines regarding DCB application.

Main Results:

• DCBs deliver antiproliferative medication directly to the vessel wall, promoting healing without metallic implants.
• Emerging evidence suggests DCBs can simplify PCI procedures at bifurcations.
• DCBs show potential for reducing target lesion failure in select bifurcation cases.

Conclusions:

• Drug-coated balloons represent a promising advancement in managing coronary bifurcation disease.
• DCBs may offer a less complex and effective alternative to traditional stenting techniques.
• Further research is needed to define optimal patient and lesion selection for DCB therapy at bifurcations.
