SCAI 2026 Workshop on the Treatment of Pulmonary Embolism-Preprocedural Evaluation: Imaging and Device Selection, Dr. Aggarwal

Preprocedural Evaluation: Imaging and Device Selection, Dr. Aggarwal

Video Transcription

Video Summary

The speaker explains how to interpret CT imaging in suspected pulmonary embolism by distinguishing acute, chronic, and acute-on-chronic clot patterns. Chronic clot appears wall-adherent and can occlude vessels, while acute clot shows contrast flowing around the defect. Three cases illustrate this: a woman with SVT and severe chronic PE requiring ECMO and surgical endarterectomy; a man with a recent brain surgery and acute PE treated by thrombectomy; and a young woman with syncope and mixed acute/chronic disease. The key takeaway is to match treatment to the clinical and imaging phenotype, not to diagnose chronic PE by procedural failure.
