Refractory cardiogenic shock (RCS) in acute myocardial infarction (AMI) is associated with high rates of mortality. Smaller ventricular assist devices, such as the intraaortic balloon pump, provide limited support. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) offers more robust mechanical ventricular support, but is not widely utilized by interventional cardiologists. This study aimed to evaluate the patient characteristics and outcomes of VA-ECMO with RCS in the setting of AMI. ⋯ VA-ECMO is infrequently used in patients for cardiopulmonary resuscitation in the AMI setting. When used judiciously, it has good clinical outcomes in this group of patients. However, use of VA-ECMO should be individualized based on vascular anatomy for best results. Close cooperation among interventional cardiologists, cardiovascular surgeons, cardiologists, cardiac intensivists, and perfusionists is essential for success of this therapy for RCS in AMI.
