CathMasters # 3Jun 16, 2026Crisis Control: VA-ECMO - An Ischemic Leg!
CathMasters tackle the management of limb ischemia — one of the most feared complications of peripheral VA-ECMO (veno-arterial extracorporeal membrane oxygenation) and large-bore mechanical circulatory support (MCS). Through the case of a 50-year-old woman with ischemic cardiomyopathy on VA-ECMO and Impella CP who develops right leg ischemia, the team walks through bedside assessment of the ischemic limb, equipment and technique for placing a distal perfusion catheter (DPC) on an existing ECMO circuit, strategies to mitigate limb ischemia with Impella, assessment of vascular patency during large-bore access removal, and the recognition and management of compartment syndrome.

Proctor’s Playbook: VA-ECMO
CathMasters walk through the step-by-step procedural approach to VA-ECMO (veno-arterial extracorporeal membrane oxygenation) cannulation. Building on the Data to Delivery episode, this Proctor Playbook episode covers pre-procedural planning, cannula selection, team composition and equipment, the role of the distal perfusion cannula (DPC), decision-making on mechanical left ventricular (LV) unloading, anticoagulation dosing and timing, the cannulation procedure itself, and vascular closure strategies during decannulation. The hypothetical case continues with the 36-year-old man with fulminant myocarditis, biventricular failure, and cardiogenic shock. Audio editing for this episode was performed by CardioNerds Intern, Dr. Julia Marques Fernandes.

Data to Delivery: The Evidence Base for VA-ECMO
This episode examines the foundational principles of veno-arterial extracorporeal membrane oxygenation (VA-ECMO). Utilizing a case study of a 36-year-old patient with fulminant myocarditis and biventricular failure, the panel analyzes the VA-ECMO circuit’s anatomy, clinical indications and contraindications, and the supporting evidence across various shock etiologies. The discussion also covers the debate over left ventricular (LV) unloading, the vital function of multidisciplinary shock teams, and strategies for informed consent and family counseling. This episode serves as an introduction to future discussions on cannulation techniques and complication management.
