Factors Associated With Survival-to-Discharge in Patients With High-Risk Pulmonary Embolism Requiring Venoarterial Extracorporeal Membrane Oxygenation

•A total of 33 patients with high-risk pulmonary embolism were managed with venoarterial extracorporeal membrane oxygenation during the study period.•Seventeen patients (52%) survived to discharge.•Chronic kidney disease, higher lactate, and lower pH were all associated with in-hospital mortality.•Survivors more frequently had surgical or catheter-based treatment after cannulation.•Seventy-seven percent of patients treated with anticoagulation alone did not survive to discharge.
