The patient was referred 1 year before with a history of progressive dyspnea triggered by less than ordinary activities, lower-extremity edema, and abdominal enlargement.

@naresh Restrictive cardiomyopathy may occur with a wide variety of systemic diseases. Some restrictive cardiomyopathies are rare in clinical practice and may present initially with heart failure. This type of cardiomyopathy is characterized by filling restriction, with reduced diastolic volume in one or both ventricles, normal or close to normal systolic function, and ventricular wall thickening. It may be idiopathic or associated with other diseases, such as amyloidosis, endomyocardial disease with or without eosinophilia, sarcoidosis, and hemochromatosis, among others5. In this case, the presence of amyloid deposits in the cheek mucosa biopsy indicated a diagnosis of amyloidosis, and the increase in serum beta-2 microglobulin reflected a worse prognosis
