Endocardial fibroelastosis. Clinico-pathological study of 38 cases
Pathology, Research and Practice
|March 1, 1984
Summary
Endocardial fibroelastosis (EFE) is a heart condition primarily affecting infants. This study found EFE often occurs with congenital heart defects and may result from various damaging factors impacting the endocardium.
Area of Science:
- Cardiovascular Pathology
- Pediatric Cardiology
- Developmental Biology
Background:
- Endocardial fibroelastosis (EFE) is a rare cardiac condition characterized by thickening of the endocardium.
- Infants are disproportionately affected, with a high incidence in the first year of life.
- EFE can be primary or secondary to other congenital heart malformations.
Purpose of the Study:
- To investigate the clinico-pathological features of endocardial fibroelastosis (EFE).
- To determine the prevalence of primary versus secondary EFE.
- To explore potential etiological factors associated with EFE.
Main Methods:
- A retrospective clinico-pathological study.
- Analysis of 38 autopsy cases diagnosed with endocardial fibroelastosis (EFE).
- Histological examination of cardiac tissues to assess endocardial involvement and associated pathologies.
Main Results:
- 82% of EFE cases occurred in infants under one year old.
- Primary EFE was identified in 55% of cases, while secondary EFE associated with congenital heart defects was found in 44%.
- Maternal pathological conditions during pregnancy were noted in 24% of cases; left heart chambers were most affected, but right chambers also showed histological changes.
Conclusions:
- Endocardial fibroelastosis (EFE) presents a diverse morphological spectrum, suggesting a common reactive pathway.
- EFE likely represents the endocardium's response to various damaging agents.
- The high association with congenital heart malformations underscores the complexity of EFE etiology.

01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
01:27Myocarditis II: Clinical Features and Diagnostic Tests
Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
01:22Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:25Cardiomyopathy I: Introduction and Classification
Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...
01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
