Video Summary

Dr. Rucha Parikh, a cardiologist, presents on interpreting coronary CT angiography (CTA) using the CAD-RADS 2.0 system for assessing plaque types, stenosis severity, and ischemia to guide clinical decisions. CAD-RADS grades stenosis from 0% (no disease) to 100% (occlusion) and classifies plaque burden (P1-P4) based on calcium scores and vessel involvement. Ischemia is evaluated with CT-based tests (CTFFR/perfusion). Three patient cases illustrate CAD-RADS application: a low-risk 44-year-old woman with no plaque (CAD-RADS 0); a 71-year-old man with mild stenosis, high plaque burden (P3), but no ischemia (CAD-RADS 2, I-); and a 61-year-old man with severe LAD stenosis (70-99%), high-risk plaque features, and a CAD-RADS 4A rating, treated with stenting. Another case involved a 47-year-old man with severe RCA stenosis (CAD-RADS 4A), confirmed by angiography and stented. The presentation emphasizes integrating anatomical and functional data to tailor preventive and interventional management.
