Excerpt
Cardiac amyloidosis is characterized by the abnormal deposition of misfolded proteins in the heart.

2 A characteristic feature of amyloid proteins are the wrinkled ß-pleated sheets formed within infiltrated tissues. In the majority of cases, cardiac amyloid can be attributed to light chain amyloid (AL) or transthyretin amyloid (ATTR) protein accumulation. ATTR may be further sub-classified as wild type (senile) or gene mutation (familial).
2 Clinically, ATTR and AL can be similar and distinguishing between them may be a challenge. Scintigraphy using technetium-99m (
99mTc) labeled bone tracers is helpful in detecting cardiac amyloid and may help differentiate between ATTR and AL cardiac amyloid. …
