What are equipment options for bifurcation lesions?

• A. Larger catheter (7F or 8F)
• B. Two guide wires, two balloons/stents and inflation devices
• C. Intravascular ultrasound only
• D. One guide wire and one balloon

Answer: (B)

The key idea is that bifurcation lesions often require access and treatment in both the main vessel and the side branch, with a strategy that protects and treats two pathways simultaneously. Having two guide wires—one in each branch—allows you to wire and maintain access to both lumens as you work. Two balloons or stents plus inflation devices give you the tools to deploy and optimize devices in both branches and to perform various two-stent or provisional techniques without losing access to either vessel. This setup provides the flexibility needed to ensure good scaffolding and patency of both the main and side branches.

Larger catheters aren't inherently required just for bifurcation treatment, and intravascular ultrasound, while helpful for imaging and optimization, is an adjunct rather than the essential equipment set. A single guide wire and a single balloon cannot adequately address the need to treat both branches and protect the side branch during stenting.
