Activity Summary

Required reading for all learners: Implicit Bias impacts patient outcomes

Weaning from veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support is a real challenge and the echocardiogram is fundamental. We found as echocardiographic parameters related to weaning success a higher left ventricular outflow tract time–velocity integral, 1:1 aortic valve opening, and qualitative normal right ventricular function, highlighting the left ventricular ejection fraction (LVEF) as independent predictor with a cut-off value >33.4%.

Objectives

  • Describe the challenge of weaning patients with hemodynamic instability off of venoarterial extracorporeal membrane oxygenation (VA-ECMO).
  • Identify echocardiographic parameters during the weaning test related to final successful disconnection from VA-ECMO.
  • Find an optimal cutoff point of left ventricular ejection fraction to discriminate patients with successful VA-ECMO weaning.
