S01E32: HI-PEITHO and the Management of Intermediate-Risk Pulmonary Embolism

In this episode of PRISM Rounds, we review the HI-PEITHO trial and its accompanying editorial, both published in The New England Journal of Medicine, and examine their implications for the contemporary management of intermediate-risk pulmonary embolism.The discussion focuses on a clinically consequential subgroup of patients with acute pulmonary embolism who are hemodynamically stable yet demonstrate right ventricular dysfunction, myocardial injury, and signs of physiologic distress. We analyze the trial design, inclusion criteria, primary composite outcome, and safety results, with particular attention to the finding that ultrasound-facilitated catheter-directed thrombolysis was associated with a lower risk of early clinical deterioration, driven largely by a reduction in cardiorespiratory decompensation rather than a demonstrated mortality benefit.We also discuss how these data may influence multidisciplinary Pulmonary Embolism Response Team deliberations, especially when evaluating whether selected patients with intermediate-risk PE may benefit from earlier catheter-based intervention rather than continued observation with anticoagulation alone. The episode places HI-PEITHO in the broader context of prior thrombolysis literature, evolving reperfusion strategies, and the persistent tension between preventing hemodynamic collapse and avoiding bleeding complications.Key topics include patient selection, interpretation of the primary end point, safety considerations, the role of physiologic distress in escalation decisions, and the likely effect of this trial on real-world PERT practice.Primary Article: https://pubmed.ncbi.nlm.nih.gov/41910345/Editorial:https://pubmed.ncbi.nlm.nih.gov/41910345/This episode is intended for educational purposes only and should not be construed as medical advice.
