Overview
Endocardial fibroelastosis (EFE) is a condition characterized by excessive fibrosis of the endocardium, leading to impaired ventricular function and often associated with congenital heart disease, particularly in infants and young children 15.Diagnosis
Clinical Presentation: Symptoms may include dyspnea, tachycardia, and signs of heart failure 13.
Electrocardiography (ECG): Abnormal ECG findings indicative of left ventricular overload 3.
Echocardiography: Essential for visualizing left ventricular hypertrophy and function 3.
Cardiac Catheterization: Useful for measuring left ventricular end-diastolic pressure and ejection fraction 3.
Histopathology: Confirms diagnosis through characteristic fibrotic changes in endocardial tissue 5.
Genetic Testing: Considered in familial cases to assess inheritance patterns 16.Management
Medical Management: Diuretics, ACE inhibitors, and beta-blockers to manage heart failure symptoms 3.
Symptom Relief: Focus on alleviating symptoms and monitoring progression 3.
Surgical Interventions: Considered in severe cases with refractory heart failure 3.
Supportive Care: Includes nutritional support and management of complications 3.Special Populations
Pediatrics: EFE predominantly affects infants and young children, with variable outcomes based on severity and treatment 135.
Genetic Considerations: Familial cases suggest potential autosomal or X-linked dominant inheritance with reduced penetrance 16.Key Recommendations
Conduct thorough family history assessment to identify potential hereditary patterns in EFE management (Evidence: Moderate 16).
Utilize echocardiography and cardiac catheterization for monitoring disease progression and response to therapy (Evidence: Moderate 3).
Implement medical management strategies including diuretics and ACE inhibitors for symptom control in symptomatic patients (Evidence: Weak 3).References
