[Extracorporeal membrane oxygenation for rescuing 12 children with acute fulminant myocarditis]

Area of Science:

• Pediatric Cardiology
• Critical Care Medicine
• Cardiovascular Surgery

Background:

• Acute fulminant myocarditis (AFM) is a severe condition in children, often leading to cardiogenic shock and life-threatening arrhythmias.
• Extracorporeal membrane oxygenation (ECMO) offers a potential rescue therapy for pediatric AFM patients refractory to conventional treatment.
• Effective management requires precise timing of ECMO intervention and skilled resuscitation techniques.

Purpose of the Study:

• To evaluate the clinical outcomes of pediatric patients with AFM treated with ECMO.
• To identify critical factors influencing survival and complications in ECMO-supported AFM cases.
• To summarize essential elements for successful ECMO cardiopulmonary resuscitation (ECPR) in pediatric AFM.

Main Methods:

• Retrospective analysis of 12 pediatric AFM patients treated with ECMO between September 2009 and August 2015.
• Focus on ECMO intervention timing for cardiogenic shock and hypoperfusion.
• Analysis of ECMO cardiopulmonary resuscitation (ECPR) essentials for cardiac arrest.

Main Results:

• Ten out of 12 (83%) pediatric AFM patients survived ECMO treatment.
• Six out of 8 (75%) patients undergoing ECPR survived.
• Common complications in survivors included cannula site bleeding, hypernatremia, intracranial hemorrhage, and cerebral injury.

Conclusions:

• Optimal ECMO intervention timing and a skilled ECMO team are crucial for improving survival rates in pediatric AFM.
• For ECPR in pediatric AFM, maintaining effective chest compressions is key to survival and long-term quality of life.
• ECMO is a viable rescue strategy for pediatric AFM, but careful patient selection and management are essential.
