Endomyocardial fibrosis in the child

Area of Science:

• Pediatric Cardiology
• Cardiovascular Surgery
• Rare Diseases

Background:

• Endomyocardial fibrosis (EMF) is a rare pediatric cardiac condition, primarily seen in tropical regions.
• The exact cause of EMF remains unknown, posing diagnostic and therapeutic challenges.
• Recent advancements in surgical techniques have improved survival rates for affected children.

Purpose of the Study:

• To report on four pediatric cases of endomyocardial fibrosis, detailing their presentation, diagnostic findings, and surgical management.
• To evaluate the efficacy of surgical interventions in improving clinical outcomes for children with EMF.
• To highlight the diagnostic capabilities of echocardiography in identifying EMF.

Main Methods:

• Case series involving four pediatric patients (one Swiss boy, three African girls) with advanced heart failure (NYHA Class III-IV).
• Diagnostic workup included echocardiography (bidimensional and Doppler) and cardiac catheterization.
• Surgical procedures included endocardectomy and valve repair/replacement.

Main Results:

• Echocardiography revealed typical findings of decreased ventricular distensibility and impaired filling.
• Three patients underwent surgical intervention (endocardectomy, valve repair/replacement), with two showing significant clinical improvement (NYHA Class II).
• One patient died; surviving patients exhibited persistent restrictive cardiomyopathy despite surgical palliation.

Conclusions:

• Surgical intervention for pediatric endomyocardial fibrosis provides palliative benefits, improving symptoms and functional class.
• Bidimensional and Doppler echocardiography are crucial for accurate diagnosis of EMF.
• EMF remains a challenging condition, with surgery offering temporary relief rather than a cure.
