Escalating Support in Severe PE: Biomarker Trends, Imaging, and ECMO Criteria
Course overview
This course reviews the clinical guidelines for acute pulmonary embolism, from risk stratification and the five updated clinical categories to the selection and technique of catheter-based therapies. Lessons cover triaging response team calls, interpreting right ventricular function, anticoagulation choices, procedural endpoints, and the evolving evidence for thrombolysis and thrombectomy. Additional topics address response team design, the operationalization of randomized trials, and strategies for distinguishing acute from chronic clot in complex cases. Learn from Drs. Sanjum Sethi, Jay Giri, Trevor Cummings, Timothy Fernandes, Robert Lookstein, Hady Lichaa, Michael Barraza, and Harris Chengazi.
