Scintigraphic characterization of amyloid cardiomyopathy.
Amyloidosis is an important entity in the differential diagnosis of cardiac failure of undetermined etiology. In this case report, the typical pattern of combined systolic and diastolic impairment in amyloid cardiomyopathy was demonstrated by analysis of the cardiac blood pool study. In addition, the patient described had mild uptake of Ga-67 citrate, as well as the characteristically intense myocardial uptake of Tc-99m pyrophosphate. Scintigraphic assessment may be particularly helpful when the diagnosis of amyloidosis is being considered in a patient with unexplained cardiac failure.
