Conversations in Interventional Cardiology: Early Clinical Experience with CrossFAST, a Novel Microcatheter-Led Delivery System for Complex Percutaneous Coronary Intervention-CIC: CrossFAST

Video Transcription

Video Summary

The discussion centered on a new guide extension catheter system, CrossFast, recently reported in J-SKY. Dr. Yang described four successful complex PCI cases using the device, including severely calcified, tortuous coronary anatomy where conventional delivery methods had failed. CrossFast uses a microcatheter-led design with a smooth tapered transition, a snap-fit mechanism, and a stiff hypotube to improve trackability and reduce vessel trauma, dissections, and the need for balloon-assisted tracking.  <br /><br />Drs. Woolmoth and Serhal emphasized its potential value in CTOs, calcified lesions, bifurcations, and challenging anatomy, while noting possible limitations such as size, compatibility with imaging and specialty balloons, and cost. Overall, the panel viewed CrossFast as a promising, safer, and more deliverable alternative to traditional guide extensions, with further studies and larger device sizes needed to define its role.
