# Importance of extracorporeal membrane oxygenation (ECMO) in congenital heart diseases: a systematic review

## TL;DR

This systematic review examines the role of ECMO in treating congenital heart diseases in children, highlighting its benefits and risks.

## Contribution

The study provides a comprehensive analysis of ECMO outcomes in pediatric CHD patients through a systematic review.

## Key findings

- Overall mortality rate was 45.2% among ECMO-treated patients.
- Successful weaning from ECMO occurred in 73.9% of cases.
- Common complications included bleeding (42.9%), renal failure (42.5%), and sepsis (27.5%).

## Abstract

Congenital heart diseases (CHDs) represent a significant healthcare challenge with incidence rates of 17.9 per 1000 live births. Extracorporeal membrane oxygenation (ECMO) has become an invaluable therapeutic option providing essential aid to support both cardiac as well as pulmonary failure.

A systematic search was performed using PubMed, Embase, and Scopus from 2000 till date. Observational studies involving pediatric patients with CHD undergoing cardiac surgery using ECMO were included. The main outcomes were to determine short-term mortality, weaning off ECMO, complications, hospital and ICU length of stay, and indications for ECMO. Assessment of the risk of bias of included studies was done by Newcastle–Ottawa scale.

24 retrospective observational studies, encompassing 1,658 patients, were ultimately included in our review. The overall incidence of mortality across these studies was 45.2%. Successful weaning from ECMO was achieved in 73.9% of patients. The most frequently reported complications included bleeding, which affected 42.9% of patients, renal failure in 42.5%, and sepsis in 27.5%. The mean duration of hospital stay was 47.8 ± 41.1 days, while the mean length of stay in the ICU was 33.4 ± 32.6 days.

ECMO benefits pediatric heart patients but comes with risks like bleeding and high mortality. Percutaneous techniques can reduce complications; more research on minimally invasive approaches is needed.
