Summary: Dr. Irtaza Asar and returning guest Dr. Hitesh Gidwani discuss how to manage physiologically unstable pulmonary embolism (PE), from activating a PE response team (PERT) to choosing among anticoagulation, thrombolysis, thrombectomy, surgery, and ECMO. They focus on bedside assessment and practical preparation, including the high-risk decision to intubate a patient with right ventricular strain. Key Takeaways The Power of PERT: Dr. Hitesh Gidwani explains how Pulmonary Embolism Response Teams bring together multidisciplinary expertise to coordinate timely, individualized care for patients with significant PE. Risk Stratification Beyond the Guidelines: The discussion compares traditional European risk categories with the newer AHA/ACC classification, emphasizing that clinical judgment and bedside assessment remain essential. Treat the Patient, Not the Classification: Management should be guided by the patient's clinical trajectory, hemodynamics, oxygenation, contraindications, procedural risks, and available resources rather than risk categories alone. ECMO as a Bridge: In patients with cardiac arrest or profound hemodynamic instability, ECMO may provide temporary circulatory support and serve as a bridge to definitive intervention in appropriately selected patients. Knowing When Not to Intervene: Many intermediate-risk PE patients can be safely managed with anticoagulation and close monitoring. Dr. Gidwani emphasizes avoiding unnecessary interventions driven by clinician anxiety rather than patient deterioration. Choosing the Right Reperfusion Strategy: The conversation explores systemic thrombolysis, catheter-directed therapies, mechanical thrombectomy, and surgical embolectomy, highlighting their potential benefits, procedural risks, and the limitations of comparative evidence. Optimizing the Failing Right Ventricle: Early hemodynamic monitoring, cautious fluid administration, thoughtful oxygenation strategies, and selective use of inhaled pulmonary vasodilators can help support patients with significant RV dysfunction. The High-Risk Airway: Intubation in patients with severe PE can precipitate cardiovascular collapse. When unavoidable, clinicians should optimize hemodynamics before induction, anticipate the effects of positive-pressure ventilation, and prepare rescue strategies.
