Cardiac amyloidosis in hereditary neuropathic amyloidosis diagnosed by endomyocardial biopsy. 1978

J P Galichia, and F L Gobel, and C S Alexander

A 57 year old male first developed progressive neuropathy of the lower extremities and then similar involvement in the upper extremities. Two years later he developed dyspnea and then complete atrioventricular block requiring the use of a permanent cardiac pacemaker. An older brother had an almost identical clinical course, including the installation of a permanent pacemaker. Both died of left ventricular failure. An endomyocardial biopsy revealed extensive amyloidosis and fibrosis of the myocardium. This is the first report of a myocardial biopsy showing amyloid on electron microscopy.

D009202	Cardiomyopathies	A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).

D000686	Amyloidosis	A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits.	Amyloidoses
