title: [Negativity of myocardial scintigraphy with technetium-pyrophosphate in a case of primary cardiac amyloidosis].
abstract: We describe herein the case of a 62-year-old man affected by congestive heart failure of obscure origin, in which the clinical history, the electrocardiographic and echocardiographic findings were compatible with the diagnosis of amyloid cardiomyopathy. Cardiac catheterization disclosed a restrictive physiology. Tc-99m-pyrophosphate myocardial scintiscan was negative despite the markedly increased left ventricular wall thickness on echocardiographic examination. A definite diagnosis was obtained by means of endomyocardial biopsy.
