Overview
Restrictive cardiomyopathy is the least common cardiomyopathy. It is called this because it restricts the heart from stretching and filling with blood properly. Rhythmicity and contractility of the heart may be normal, but the stiff walls of the heart chambers (atria and ventricles) keep them from adequately filling. So blood flow is reduced, and blood that would normally enter the heart is backed up in the circulatory system. In time, restrictive cardiomyopathy patients develop heart failure.
Causes of Restrictive Cardiomyopathy
- Alpha-L-iduronidase deficiency (Hurler syndrome)
- Amyloidosis
- Carcinoid tumours and carcinoid syndrome
- Endocardial fibroelastosis
- Endomyocardial fibrosis
- Gangliosidosis GM1, type 1
- Gaucher disease
- Hemochromatosis
- Löffler's syndrome
- Mucolipidosis II alpha/beta
- Paraneoplastic syndrome
- Postradiation fibrosis
- Sarcoidosis
- Systemic sclerosis
Diagnosis
Electrocardiogram
Shown below is an example of restrictive cardiomyopathy with low voltage and flipped anterior T waves.
