Insights

Younger patients (≤40 years) treated with venoarterial extracorporeal membrane oxygenation (VA-ECMO) after cardiac surgery have better survival rates. However, mortality remains high even in this group, with limited use of heart transplantation.

Area of Science:

  • Cardiology
  • Cardiovascular Surgery
  • Critical Care Medicine

Background:

  • Post-postcardiotomy cardiogenic shock necessitates advanced support.
  • Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is a critical intervention for severe cardiogenic shock.
  • Outcomes of VA-ECMO in young adult cardiac surgery patients require detailed evaluation.

Purpose of the Study:

  • To assess early and midterm mortality in young adult patients undergoing VA-ECMO post-cardiac surgery.
  • To identify age-related differences in outcomes and treatment strategies.
  • To evaluate the impact of heart transplantation on survival in different age groups.

Main Methods:

  • Systematic literature review of studies on postcardiotomy VA-ECMO in adults.
  • Individual patient-level data analysis from 10 contributing studies.
  • Inclusion of 1268 patients from 25 hospitals, with adjusted mortality analyses.

Main Results:

  • Age 40 years was a significant cutoff for in-hospital and 24-month mortality.
  • Patients >40 years had significantly higher in-hospital (68.8% vs 43.1%) and 24-month mortality (73.7% vs 45.0%).
  • Heart transplantation was more frequent in younger patients (11.0% vs 2.9%) and associated with reduced mortality, particularly in older patients.

Conclusions:

  • Younger patients (≤40 years) demonstrate significantly lower early and midterm mortality after postcardiotomy VA-ECMO compared to older patients.
  • Despite better outcomes, mortality remains substantial in younger patients.
  • Heart-replacement therapies are underutilized in younger patients, potentially due to severe perioperative complications.
