Article Abstract
Background: VA-ECMO with concomitant Impella support (ECpella) is an emerging treatment modality for cardiogenic shock (CS). Survival outcomes by CS etiology with ECpella support have not been well-described.
Methods: This study was a retrospective, single-center analysis of patients with cardiogenic shock due to acute myocardial infarction (AMI-CS) or decompensated heart failure (ADHF-CS) supported with ECpella from December 2020 to January 2023. Primary outcomes included 90-day survival post-discharge and destination after support. Secondary outcomes included complications post-ECpella support.
Results: A total of 44 patients were included (AMI-CS, = 20, and ADHF-CS, = 24). Patients with AMI-CS and ADHF-CS had similar survival 90 days post-discharge ( = .267) with similar destinations after ECpella support ( = .220). Limb ischemia and acute kidney injury occurred more frequently in patients presenting with AMI-CS (013; = .030). Patients with initial Impella support were more likely to survive ECpella support and be bridged to transplant (=.033) and less likely to have a cerebrovascular accident =.016). Sub-analysis of ADHF-CS patients into acute-on-chronic decompensated heart failure and de novo heart failure demonstrated no difference in survival or destination.
Conclusion: ECpella can be used to successfully manage patients with CS. There is no difference in survival or destination for AMI-CS and ADHF-CS in patients with ECpella support. Patients with initial Impella support are more likely to survive ECpella support and bridge to transplant. Future multicenter studies are required to fully analyze the differences between AMI-CS and ADHF-CS with ECpella support.

Harlequin Syndrome in Venoarterial ECMO and ECPELLA: When ECMO and Native or Impella Circulations Collide - A Comprehensive Review.

Harlequin syndrome, also known as differential hypoxia (DH) or North-South syndrome, is a serious complication of femoro-femoral venoarterial extracorporeal membrane oxygenation (V-A ECMO). Moreover, Harlequin syndrome is caused by competing flows between the retrograde oxygenated ECMO output and the anterograde ejection of poorly oxygenated blood from the native heart. In the setting of impaired pulmonary gas exchange, the addition of an Impella device (ECPELLA configuration), although beneficial for ventricular unloading and hemodynamic support, may further exacerbate this competition and precipitate DH.

Cardiogenic shock during liver transplantation (LT) is a significant challenge, particularly in patients with comorbidities like end-stage renal disease (ESRD). Mechanical circulatory support (MCS), including veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is increasingly used to manage refractory shock in these complex cases. This case report discusses the management of a 69-year-old patient who developed intraoperative refractory cardiogenic shock while undergoing combined liver-kidney transplantation and was supported with VA-ECMO and Impella 5.

Cardiogenic shock (CS) is a complex, multifactorial syndrome with substantial morbidity and mortality. Despite neutral results from randomized controlled trials, venoarterial extracorporeal membrane oxygenation (VA-ECMO) may be reasonable for select patients with refractory CS. A 37-year-old woman with morbid obesity and dilated nonischemic cardiomyopathy presented with Society of Cardiovascular Angiography and Intervention stage D biventricular CS, requiring vasopressor support and emergent escalation to ECPELLA, the combination of VA-ECMO and Impella (Abiomed), as a bridge to decision.

Background: Takotsubo syndrome (TTS) is a transient cardiac condition primarily affecting left ventricular function and is often triggered by physical or emotional stress. Biventricular involvement in TTS has been recently reported, and such cases are associated with a more severe clinical presentation. However, biventricular TTS with cardiogenic shock (CS) requiring mechanical circulatory support (MCS) is rare.

Background: The combination of VA-ECMO and Impella, known as "ECpella" offers an alternative to the method of left ventricle unloading with intra-aortic balloon pump (IABP). Limited information is available to inform anticoagulation management in cases of concomitant use of Mechanical Circulatory Support (MCS) devices.
Methods: This retrospective study included 34 patients receiving hemodynamic support through concomitant MCS for cardiogenic shock for a duration exceeding 24 h.
