SCAI 2026 CT-Guided PCI: The Emerging Role of CT for Pre-Procedural Planning-CT-Based Plaque and Calcium Assessment to Inform Lesion Preparation, Dr. Collet

CT-Based Plaque and Calcium Assessment to Inform Lesion Preparation, Dr. Collet

Video Transcription

Video Summary

The speaker explains how CT helps assess coronary calcium for planning complex PCI. CT now provides 3D views plus calcium density, revealing whether calcium is soft or hard and improving prediction of plaque modification needs and stent underexpansion. Studies show density may outperform traditional measures like arc and length in predicting rotational atherectomy and final stent expansion. Based on these findings, a new randomized trial is comparing CT-guided versus IVUS-guided calcium management in severely calcified lesions. The main conclusion: calcium density may become essential for planning complex PCI.
