Cardiac amyloidosis--diagnosis by 2-dimensional echocardiography.

: In the past, the precise diagnosis of amyloid cardiomyopathy without resort to invasive techniques has been difficult. Recent experience with 2-dimensional echocardiography in cardiac amyloidosis has suggested that there are characteristic, and perhaps unique, features that are regularly imaged. We describe a case where usage of this non-invasive technique allowed accurate definition of cardiac involvement by amyloid.
