Echocardiographic aspects of cardiac amyloidosis

Abstract

We report the M-mode and two-dimensional echocardiographic findings in a patient with familial amyloidosis. The diagnosis was made by the clinical picture and histologic evidence of amyloid in peripheral nerve biopsy. Though the patient had no clinical sign of heart failure, extensive involvement of the heart was demonstrated by echocardiography. M-mode echocardiography revealed increased right ventricular wall thickness in conjunction with symmetric increase in left ventricular wall thickness. On two-dimensional echocardiography, the entire interventricular septum and the papillary muscles were more dense than normal. These high density echoes had a "granular and sparkling" pattern. This case shows that cardiac amyloidosis can be diagnosed in the pre-clinical, asymptomatic state by M-mode and two-dimensional echocardiography. When symptomatic, confusion with constrictive pericarditis may be avoided non-invasively.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
