Insights
Extracorporeal life support (ECLS) offers excellent survival rates for children with acute fulminant myocarditis. This study found that 92.3% of pediatric patients requiring mechanical circulatory support survived.
Area of Science:
- Pediatric Cardiology
- Critical Care Medicine
- Cardiovascular Surgery
Background:
- Severe acute myocarditis in children often necessitates mechanical circulatory support.
- The clinical outcomes for pediatric patients with acute fulminant myocarditis requiring extracorporeal life support (ECLS) are not well-established.
Purpose of the Study:
- To investigate the survival rates and clinical courses of children with acute fulminant myocarditis who were treated with ECLS.
Main Methods:
- A retrospective chart review was conducted on 13 consecutive pediatric patients with acute fulminant myocarditis treated with ECLS.
- Data collected included demographics, symptoms, laboratory results, management strategies, clinical course, and follow-up status.
Main Results:
- The median age was 25.8 months, and the median body weight was 10.3 kg.
- The median ECLS duration was 140 hours, with a median intensive care unit stay of 16 days.
- Twelve out of 13 patients (92.3%) survived to discharge, with most recovering from ventricular dysfunction or undergoing heart transplantation.
Conclusions:
- Extracorporeal life support (ECLS) can serve as a primary treatment modality for pediatric acute fulminant myocarditis.
- ECLS demonstrates excellent clinical outcomes and high survival rates in this critically ill pediatric population.
Objectives:
The clinical outcome of children with severe acute myocarditis who require mechanical circulatory support is not well known. Therefore, we studied the survival and clinical courses of patients with acute fulminant myocarditis supported by extracorporeal life support (ECLS).
Methods:
We performed a retrospective chart review of 13 consecutive children with acute fulminant myocarditis who were treated with ECLS between April 2013 and April 2015. Demographics, initial symptoms, laboratory results, management, clinical courses and last follow-up status were investigated.
Results:
The median age was 25.8 months (range, 2.9 months to 11.5 years) and the median body weight was 10.3 kg (range, 5.3-47.5 kg). All patients received the ECLS procedure via peripheral approach (right neck). The median ECLS duration was 140 h (range, 51-425 h). The median intensive care unit stay was 16 days (range, 4-44 days). Viral pathogens were detected in 7 patients. Six patients underwent left-heart decompression using a catheter-based technique, which was performed using atrial septostomy and leaving a left atrial venting cannula. Eleven patients recovered from ventricular dysfunction, and 2 patients underwent successful orthotopic heart transplantation. Ultimately, 12 patients (92.3%) survived to discharge. The deceased patient succumbed to unrestored brain function due to enterovirus encephalitis, and the patient's parents chose to donate other organs.
Conclusions:
Mechanical circulatory support using ECLS can be a first-line treatment that confers excellent clinical outcomes for children with acute fulminant myocarditis.
