The frequency of cardiac involvement varies among other types of amyloidosis. Cardiac amyloidosis leads to systolic and diastolic dysfunction with symptoms of heart failure. Cardiac magnetic resonance (CMR) findings are helpful in supporting the diagnosis of amyloid cardiomyopathy. We report a case of a 73-year-old man who presented with shortness of breath. Echocardiography showed a hypertrophic, diffusely hypocontractile left ventricle with a restrictive filling pattern. The diagnosis of an isolated amyloidosis was made on CMR.
