[Case of lifetime diagnosis of isolated primary amyloidosis of the heart]

The article presents a case of intravital diagnosis of a rare heart disease, isolated primary amyloidosis. The clinical onset of the disease was heart failure (HF) that was resistant to treatment; chemotherapy was ineffective and was poorly tolerated by the patient. The diagnostics was based on a combination of refractory HF and changes in echocardiography data (atrial dilatation, small size of the left ventricular cavity, interventricular septal hypertrophy with the presence of hyperechoic inclusions of the "granular fluorescence" type), and changes detected by contrast-enhanced cardiac magnetic resonance imaging. The diagnosis of amyloidosis was confirmed by results of pathohistological examination of the material obtained during autopsy.

AL-amyloidosis with cardiac involvement. Diagnostic capabilities of non-invasive methods

There are presented the literature data and a description of the clinical course of the disease in isolated/predominant cardiac amyloidosis. Amyloid cardiomyopathy is the most common phenocopy of hypertrophic cardiomyopathy. The modern possibilities of non-invasive diagnostics using osteoscintigraphy for the differential diagnosis between amyloid cardiomyopathy caused by AL- and transthyretin amyloidosis are described in detail.
