I42.4
Endocardial fibroelastosis
Clinical Classification Guidelines
Inclusion Terms
- Congenital cardiomyopathy
- Elastomyofibrosis
Medical Intelligence & Overview
Endocardial fibroelastosis is a rare heart condition characterized by the thickening of the innermost layer of the heart, known as the endocardium. This thickening involves the accumulation of fibrous and elastic tissue, which can interfere with the heart's ability to pump blood efficiently. Although it can occur at any age, it is most commonly diagnosed in infants and young children. The condition is considered a form of congenital cardiomyopathy, meaning it is present at birth and involves abnormal heart muscle structure.
Causes & Symptoms
Clinical Causes: Genetic factors: Some cases are linked to inherited genetic mutations Infections during pregnancy: Certain viral infections may contribute to the development Other congenital heart defects: May coexist with or contribute to the development of fibroelastosis Unknown factors: In many cases, the exact cause remains unidentified
Key Symptoms: Difficulty feeding or poor weight gain in infants Breathing difficulties, including rapid breathing or shortness of breath Fatigue and weakness Swelling in the legs, ankles, or abdomen due to fluid buildup Frequent respiratory infections In severe cases, signs of heart failure such as cyanosis (bluish discoloration) may occur
Diagnostic & Treatment
Diagnosis Path: Diagnosing endocardial fibroelastosis involves a combination of medical history review, physical examination, and diagnostic tests. Echocardiography (heart ultrasound) is the primary tool used to visualize the thickening of the endocardium and assess heart function. Additional tests such as electrocardiograms (ECG), chest X-rays, MRI scans, or cardiac catheterization may be employed to gather more detailed information and rule out other heart conditions.
Treatment Protocols: Medications: To manage heart failure symptoms, such as diuretics, ACE inhibitors, or beta-blockers Supportive care: Including nutritional support and oxygen therapy if needed Monitoring: Regular follow-up with a cardiologist to assess disease progression Surgical intervention: In severe cases, procedures like endocardial resection or heart transplantation may be considered Lifestyle modifications: As advised by healthcare providers, to reduce overall cardiac stress
