Myocarditis in Paediatric Patients: Unveiling the Progression to Dilated Cardiomyopathy and Heart Failure

Area of Science:

• Cardiology
• Pediatric Medicine
• Pathology

Background:

• Myocarditis presents a significant health challenge in children, potentially causing severe illness and progressing to dilated cardiomyopathy.
• Diverse causes exist, with viral infections being most common in developed nations, though bacterial, protozoal infections, and drug hypersensitivity are also implicated.
• Diagnosing pediatric myocarditis is complex due to a wide range of clinical presentations, from asymptomatic cases to sudden cardiac death.

Purpose of the Study:

• To review recent advancements in understanding pediatric myocarditis.
• To explore the disease's progression to dilated cardiomyopathy.
• To discuss updated diagnostic and therapeutic approaches.

Main Methods:

• Literature review focusing on recent studies of pediatric myocarditis.
• Analysis of diagnostic modalities including endomyocardial biopsy and non-invasive tools.
• Examination of treatment strategies, including the role of intravenous immunoglobulin.

Main Results:

• Myocarditis pathogenesis exhibits a triphasic nature, influencing management strategies.
• Endomyocardial biopsy is the definitive diagnostic standard, supported by various non-invasive methods.
• The efficacy of intravenous immunoglobulin in treating pediatric myocarditis remains under investigation.

Conclusions:

• Understanding the triphasic nature of myocarditis is crucial for effective patient management.
• Accurate diagnosis relies on a combination of biopsy and non-invasive techniques.
• Further research is needed to clarify treatment outcomes, particularly for intravenous immunoglobulin therapy in pediatric cases.
