This episode breaks down the 2026 AHA/ACC/ACCP/ACPPE pulmonary embolism guidelines, highlighting the biggest changes to PE risk stratification, catheter-based interventions, and long-term follow-up. It also discusses how new randomized trials like STORM-PE and HI-PEITHO are shaping the future of interventional PE care.
- Biggest Change: The traditional "massive" and "submassive" PE classifications have been replaced with a new A through E risk framework, placing greater emphasis on dynamic clinical assessment and early recognition of patient deterioration.
- High-Risk Patient: The guidelines introduce Category D2, or normotensive shock, recognizing that patients with normal blood pressure but elevated lactate or signs of end-organ hypoperfusion may require urgent intervention.
- New Data Shows: Recent randomized trials demonstrated that catheter-based therapies improve right ventricular recovery and reduce clinical decompensation in intermediate-high risk PE, although long-term mortality benefits remain under investigation.
- Safety Pearl: The guidelines strongly caution against routine deep sedation in acute PE, noting a markedly increased risk of cardiopulmonary collapse with propofol in unstable patients.
- Bottom Line: These guidelines shift PE management from static risk categories to continuous reassessment and reinforce that interventional specialists should play an active role in both acute treatment and long-term follow-up.
Tune in to learn how the new PE guidelines could change which patients receive intervention and when. Wysdom recommends that you check out PECompass.org. It was founded by Dr. Mona Ranade from Stanford IR and also a co-author of this paper. It is a great app in which you put in the clinical information about your patient and it will calculate what category your patient fits into.
