Which statement about selective engagement of the left coronary system is true?

• A. It cannot be achieved with JL shapes
• B. It uses only Amplatzer left shapes
• C. It commonly employs JL, JL-type, AL, and XB shapes
• D. It is performed only with transradial access

Answer: (C)

Engaging the left coronary system selectively relies on using catheter shapes that align the tip with the left ostium while providing enough backup to secure and stabilize the catheter. The Judkins Left family, including JL-type variants, is the classic choice for left coronary engagement because their curves are designed to reach the left ostium smoothly with favorable torque and adequate support. When the anatomy is challenging—such as a high takeoff, sharp ostial angle, or tortuous aorta—Amplatz Left catheters offer a stronger backup and a different orientation that can make engagement easier. Extra Backup catheters add still more support for stubborn anatomies or difficult catheter seating. Because of these tools, selective engagement of the left coronary system is commonly accomplished with JL-type shapes, Amplatz Left shapes, and XB shapes. Access route can be radial or femoral; transradial is common but not the only option.
