Video Summary
The discussion focused on CT-derived FFR, calcium density, and practical adoption of CT in cardiovascular care. Speakers noted that CT-FFR can predict outcomes, but its clinical benefit may not be identical to invasive FFR trials like FAME 2 because treatment effects may differ by modality and context. Calcium biology was highlighted: low-density calcium is linked to worse plaque biology, while high-density calcium may be harder for PCI. Photon-counting CT was described as a major future improvement in accuracy. They also discussed workflow barriers, the need for radiologist collaboration, and expanding CT use to peripheral artery disease and procedural planning.
