| | Heart Disease and Restrictive Cardiomyopathy |
 | | Restrictive cardiomyopathy, the rarest form of cardiomyopathy, is a condition in which the walls of the lower chambers of the heart (the ventricles) are abnormally rigid and lack the flexibility to expand as the ventricles fill with blood. |
 | | In some cases, restrictive cardiomyopathy may be confused with constrictive pericarditis, a condition in which the layers of the pericardium (the sac that surrounds the heart) become thickened, calcified, and stiff. |
 | | Restrictive cardiomyopathy is diagnosed based on medical history (your symptoms and family history), physical exam, and tests: such as blood tests, electrocardiogram, chest X-ray, echocardiogram, exercise stress test, cardiac catheterization, CT scan, MRI and radionuclide studies (Multigated Acquisition Scan). |
