High-risk/massive pulmonary embolism (PE) has a high mortality rate, especially when cardiac arrest occurs. Venoarterial (V-A) extracorporeal membrane oxygenation (ECMO) can rapidly restore and maintain circulation while a decision regarding further care or performance of other interventions takes place. Catheter-based embolectomy (CBE) is a technology that allows for percutaneous access, clot removal, and potential resolution of shock while avoiding sternotomy required for traditional pulmonary embolectomy. Rapid placement of V-A ECMO in patients with high-risk/massive PE prior to CBE may confer circulatory protection before, during, and after the procedure.
