Tips and tricks for antegrade recanalization of chronic total occlusions using the CrossBoss catheter.

Objectives: To provide new strategies and techniques for the successful recanalization of chronic total occlusions (CTOs) with the sole use of the CrossBoss catheter. In addition, some common CTO scenarios are illustrated in detail.

Background: CTOs are one of the most challenging complex coronary lesion subsets to intervene upon.

The utility of extension catheters in transradial percutaneous coronary intervention.

Objectives: To evaluate the use of extension catheters in transradial intervention of complex coronary lesions.

Background: Complex percutaneous coronary intervention (PCI) via transradial approach remains a challenge for many interventionalists, primarily due to the difficulty in obtaining adequate guide catheter support.

Methods: A retrospective case series identified 54 patients who presented for PCI of complex coronary lesions.
