Bifurcation Cases With OCT and Coronary CT-OCTOBER and P4 Trials-3D Plaque Assessment for Bifurcation CT-Based PCI Planning

Video Transcription

Video Summary

The webinar focuses on innovative approaches to coronary CT-guided percutaneous coronary intervention (PCI), specifically in bifurcation cases. Dr. Carlos Kalei introduces the P4 study which explores using CT for planning and guiding complex bifurcation procedures. CT aids in understanding complex bifurcations by detailing not just geometric information but also plaque distribution, which is crucial for predicting risks and planning procedures. Dr. Kalei suggests CT can become essential for bifurcation planning as it allows detailed mapping of the coronary artery disease, including assessing plaque characteristics and severity, aiding in treatment decisions.<br /><br />The P4 study compares CT guidance with intravascular ultrasound (IVUS) during PCI, aiming to demonstrate non-inferiority. It evaluates the comprehensive use of CT for mapping anatomy and physiology pre-procedure, aiming to standardize treatment and reduce outcome variability seen in current practices. Photon-counting CT represents future prospects for better resolution and detailing. Despite limitations—like inability to use intravascular imaging post-procedure in this study—findings may show CT’s effectiveness in enhancing PCI outcomes by providing substantial pre-procedural insights.
