Dynamic Extracorporeal Life Support in a Patient With Left Ventricular Assist Device and Electrical Storm: A Case...

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Critical Care Medicine

Background:

• Electrical storm (ES) and cardiac arrest pose significant challenges in patients with left ventricular assist devices (LVADs).
• Venoarterial extracorporeal membrane oxygenation (VA ECMO) for extracorporeal cardiopulmonary resuscitation (ECPR) in LVAD patients presents hemodynamic complexities.
• Alternative ECMO configurations may offer tailored support.

Purpose of the Study:

• To describe the management of a patient with a newly implanted LVAD who experienced electrical storm, cardiac arrest, and refractory right ventricular failure.
• To illustrate the use of staged ECMO support, including VA, hybrid VAP, and VP ECMO, in this complex clinical scenario.

Main Methods:

• The case report details a patient with a new LVAD who developed ES and cardiac arrest.
• Initial support involved VA ECMO for ECPR.
• Subsequent support transitioned to hybrid venoarteriopulmonary (VAP) ECMO and then to venopulmonary (VP) ECMO based on evolving hemodynamic requirements.

Main Results:

• The patient required complex, multi-stage ECMO support.
• Successful transition between different ECMO modes (VA to VAP to VP) was achieved.
• This staged approach addressed the patient's dynamic hemodynamic needs.

Conclusions:

• Staged ECMO support, adapting between VA, VAP, and VP configurations, can be a viable strategy for LVAD patients experiencing electrical storm and cardiac arrest.
• Tailoring ECMO mode to specific hemodynamic challenges is crucial for managing these critically ill patients.
