Key result

VA-ECMO and IABP enable neurologically intact survival and LVEF recovery to 50% following STEMI arrest.

Key Points

To evaluate the clinical utility of veno-arterial extracorporeal membrane oxygenation as a rescue therapy for refractory cardiac arrest and severe myocardial stunning following acute coronary syndrome.
Clinical presentation and intervention in a 39-year-old male with multi-vessel acute coronary occlusion who experienced intraprocedural cardiac arrest during percutaneous coronary intervention.
Implementation of rescue hemodynamic management combining veno-arterial extracorporeal membrane oxygenation (VA-ECMO), an intra-aortic balloon pump (IABP), and inotropic support following prolonged resuscitation with 50 minutes of low-flow time.
Severe metabolic shock with blood lactate exceeding 17 mmol/L was stabilized following initiation of combined VA-ECMO and IABP support.
The patient was successfully weaned from mechanical and pharmacological circulatory support after two weeks in the intensive care unit.
Left ventricular ejection fraction improved from 35% to 50% at discharge, with no permanent neurological sequelae.

Caccamo et al. (2026) conducted a case report in Inferior STEMI complicated by cardiac arrest and cardiogenic shock (n=1). Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) was evaluated. A 39-year-old man with inferior STEMI and cardiac arrest was successfully supported with VA-ECMO and IABP, resulting in survival without neurological sequelae and recovery of LVEF to 50%.
