What is endomyocardial fibrosis?
Endomyocardial fibrosis (EMF) is a disease of rural poverty that is characterized by fibrosis of the apical endocardium of the right ventricle (RV), left ventricle (LV), or both.
What is endomyocardial disease?
Endomyocardial diseases refer to a group of diseases that affect the endocardium and/or myocardium leading to myocardial injury that may range from a fully recoverable syndrome to one that leads to chronic myocardial remodelling and restrictive cardiomyopathy (RCM) [7,8].
How is myocardial fibrosis diagnosed?
Myocardial biopsies are taken from explanted hearts or during myectomy, open heart surgery or catheter-based endocardial biopsy. With heart biopsies and using appropriate staining methods, histological analysis of the volume fraction of collagen is regarded as the gold standard for detection of fibrosis (7, 10, 17).
What is Subendocardial fibrosis?
This condition is morphologically characterized by a thickened, two-layered myocardium with numerous prominent trabeculations and deep, intertrabecular recesses.
What causes endomyocardial fibrosis?
A specific single etiology of endomyocardial fibrosis (EMF) has not been established. Suggested potential causes include the following : Infectious causes, such as parasites (eg, helminths) and protozoans (eg, toxoplasmosis, malaria) Inflammatory causes: Eosinophilia.
How is an endomyocardial biopsy performed?
Myocardial biopsy is done through a catheter that is threaded into your heart (cardiac catheterization). The procedure will take place in a hospital radiology department, special procedures room, or cardiac diagnostics laboratory.
What are the symptoms of cardiac fibrosis?
The lungs and the lymph glands between the lungs are frequently affected, and symptoms may include coughing and difficulty breathing. The heart may also be affected, resulting in abnormal heartbeat patterns (conduction block, atrial arrhythmia or ventricular arrhythmia) and/or heart failure.
Why is endomyocardial biopsy performed?
Your doctor uses myocardial biopsy to: Evaluate or confirm the presence of rejection after heart transplant. Diagnose myocarditis (inflammation of the heart muscle) Diagnose cardiac amyloidosis.
What all are the indications for endomyocardial biopsy?
Indications
- Heart Failure of Unknown Etiology.
- Cardiac Sarcoidosis.
- Hypersensitivity Myocarditis.
- Suspected Anthracycline Cardiomyopathy.
- Heart Failure With a Restrictive Pattern.
- Cardiac Tumors.
- Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)
- Heart Transplant.
When is an endomyocardial biopsy needed?
Endomyocardial biopsy is absolutely necessary only for the diagnosis of a small number of diseases or conditions, including anthracycline-induced cardiomyopathy, cardiac allograft rejection, sarcoidosis, giant cell myocarditis, and hypereosinophilic syndrome, of which only allograft rejection, sarcoidosis, and …
How is endomyocardial biopsy done?
How Endomyocardial Biopsy Is Performed. While under local anesthesia, your interventional cardiologist threads a catheter (a thin, flexible tube) through a vein in your neck or groin, moving it into your heart’s right ventricle. A small piece of heart muscle tissue is then be collected.
Endomyocardial fibrosis (EMF) is a rare disease in North America but common in the tropical and subtropical regions of the developing world. It is characterized by fibrosis of the left ventricular and right ventricular endocardium which cause restrictive cardiomyopathy.
How is endomyocardial fibrosis (EIF) diagnosed?
The disease has been described in a few patients over 60 years of age and, rarely, in patients younger than 5 years of age. Echocardiography is the primary tool used to diagnose suspected cases of endomyocardial fibrosis or Loeffler’s disease. A heart muscle biopsy is sometimes obtained to confirm the diagnosis.
Is endomyocardial fibrosis associated with mumps?
In children, endomyocardial fibrosis has been associated with the mumps virus. Endomyocardial fibrosis is principally an endemic disease of the equatorial tropics. It is exceedingly rare in Europe and North America.
What is the prevalence of endomyocardial fibrosis (EMF)?
Endomyocardial fibrosis is principally an endemic disease of the equatorial tropics. It is exceedingly rare in Europe and North America. It affects all races, mostly children and young adults. The disease has been described in a few patients over 60 years of age and, rarely, in patients younger than 5 years of age.
