Insights
Cardiac catheterization during extracorporeal membrane oxygenation (ECMO) is feasible and safe in pediatric congenital heart disease patients. Procedures were often performed early and included interventions, supporting its role in selected cases.
Area of Science:
- Pediatric Cardiology
- Interventional Cardiology
- Extracorporeal Membrane Oxygenation
Background:
- Cardiac catheterization during ECMO is increasingly utilized for pediatric congenital heart disease.
- Evidence from Latin American populations is limited.
Purpose of the Study:
- To evaluate the feasibility and safety of cardiac catheterization during ECMO in pediatric patients with congenital heart disease.
- To assess outcomes including interventions, complications, and survival.
Main Methods:
- Retrospective, single-center cohort study.
- Included pediatric patients (<18 years) on ECMO support.
- Collected demographic and procedural data; outcomes analyzed.
Main Results:
- 51 of 140 ECMO patients (36%) underwent 59 cardiac catheterizations.
- 92% had complex congenital heart disease; 64% had transcatheter interventions.
- Survival to discharge was 43%; major complications were infrequent (3%).
Conclusions:
- Cardiac catheterization during ECMO is feasible and safe in this pediatric cohort.
- Procedures were performed early and often included interventions.
- Catheterization provided crucial diagnostic/therapeutic information, supporting its role in selected ECMO patients.
Background:
Cardiac catheterization during extracorporeal membrane oxygenation (ECMO) in pediatric patients with congenital heart disease is increasingly used to evaluate residual lesions and perform transcatheter interventions. However, evidence from Latin American populations remains scarce.
Methods:
We conducted a retrospective, single-center cohort study including patients under 18 years who underwent cardiac catheterization while on ECMO support between January 2012 and December 2024. Demographic and procedural variables were collected. Outcomes included successful ECMO decannulation, procedure-related complications, and survival to hospital discharge.
Results:
Among 140 pediatric patients supported with ECMO, 36% (n = 51) underwent cardiac catheterization, totaling 59 procedures. Most patients (92%) had complex congenital heart disease, with a predominance of single-ventricle physiology. In 64% of procedures, one or more transcatheter interventions were performed, most frequently balloon angioplasty or stenting of the pulmonary arteries. The median time from ECMO cannulation to catheterization was 1.25 days; 67% of procedures were performed within the first 24 h. Overall survival to hospital discharge was 43%. Major complications were infrequent (3%), and no procedure-related mortality was observed.
Conclusions:
Cardiac catheterization during ECMO was feasible and safe in this cohort. Most procedures were performed early and included transcatheter interventions. Although multivariable analysis did not identify independent predictors of survival, catheterization provided essential diagnostic and therapeutic information that influenced management. These findings support its role in selected pediatric patients supported with ECMO.
