Abstract No. 167 Large-Bore Aspiration and Catheter-Based Thrombolytic Intervention for High-Risk Pulmonary Embolism in Patients on Veno-Arterial Extracorporeal Membrane Oxygenation

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) may improve outcomes in subjects with high-risk pulmonary embolism (PE) and circulatory failure. Current guidelines recommend systemic thrombolytic treatment for appropriate candidates. However, it is uncertain if additional catheter-based interventions such as mechanical thrombectomy (MT) or catheter-directed thrombolytics (CDT) during cannulation improves outcomes such as survival. This case series reviews a cohort of 23 patients on VA-ECMO with subsequent catheter-based intervention with 19 patients presenting with cardiac arrest.
