Abstract

Objective:

To evaluate the outcomes of patients with single ventricle physiology supported with extracorporeal membrane oxygenation as a bridge to first-stage palliation.

Methods:

This was a retrospective registry-based study. Data from the Extracorporeal Life Support Organization registry were used to identify single ventricle physiology patients supported with extracorporeal membrane oxygenation prior to palliation from 2016 to 2021. Descriptive statistics and multivariate analyses for associations with mortality were conducted.

Results:

Primary outcome was death before hospital discharge. Patient characteristics including demographics and associated complications were evaluated as secondary outcomes. Sixty-five patients met inclusion criteria. Survival to discharge was 42%. Twenty-four (37%) patients died while on extracorporeal membrane oxygenation. There was no significant difference in demographics between survivors and non-survivors. Non-survivors had a significantly longer median duration on extracorporeal membrane oxygenation compared to survivors, 99-hrs [IQR (Interquartile Range), 160, 300] vs. 59-hrs [43, 124] (p<0.001). Multivariate analysis demonstrated extracorporeal membrane oxygenation duration (adjusted-OR [Odds Ratio] 1.01, 95% CI [Confidence Interval] 0.98, 0.99; p = 0.03) and requiring renal replacement therapy (42% vs. 19%; p = 0.04) were associated with mortality prior to discharge.

Conclusions:

Clinicians managing decompensated patients with single ventricle physiology may consider extracorporeal membrane oxygenation as a bridge to palliation. Survival to discharge was 42%. Evidence of renal injury and longer extracorporeal membrane oxygenation durations were associated with mortality. These data may be used to guide providers and to counsel families. However, more data are needed to refine indications and assess associations related to outcomes and decision-making.
