Infantile intracardiac thrombus in severe encephalo-myocarditis

Area of Science:

• Pediatric Cardiology
• Infectious Diseases
• Critical Care Medicine

Background:

• Myocarditis is an uncommon pediatric disease with varied presentations, demanding high clinical suspicion.
• Intracardiac thrombus formation secondary to myocarditis is a rare complication with undefined management protocols.

Purpose of the Study:

• To report a case of fulminant viral myocarditis with encephalitis and intracardiac thrombus in a child.
• To describe the challenges in managing this rare complication and propose treatment guidance.

Main Methods:

• Case report of a pediatric patient with viral prodrome, multi-organ failure, and subsequent myocarditis and encephalitis.
• Detailed description of the diagnostic and therapeutic interventions employed.

Main Results:

• The patient presented with rapid deterioration, fulminant viral myocarditis, encephalitis, and intracardiac thrombus formation.
• Successful medical treatment was achieved, despite the complexity of the presentation.

Conclusions:

• Fulminant viral myocarditis with intracardiac thrombus is a severe pediatric condition requiring prompt recognition.
• This case underscores the importance of a high index of suspicion and suggests factors for guiding treatment in similar complex pediatric cases.
