Myeloma - associated (primary) amyloidosis : Cardiac involvement occurs in approximately 90% of cases of myeloma-associated (primary) amyloidosis. In either form of cardiac amyloidosis, the dominant imaging finding is the appearance of cardiac "hypertrophy." The "hypertrophy" on imaging represents amyloid fibril deposition rather than myocyte hypertrophy/hyperplasia, which explains why ECG voltages are decreased rather than increased. Definition / general Light chain (AL) amyloidosis is the most common form of systemic amyloidosis (Clin J Am Soc Nephrol 2006;1:1331) Monoclonal immunoglobulin deposition disease with visceral and soft tissue Ig deposition resulting in organ dysfunction Amyloidosis is an increasingly recognized cause of heart disease, caused by the deposition of misfolded protein within the heart.

It may present to almost any specialty, and diagnosis is frequently delayed. 1 Cardiac involvement is a leading cause of morbidity and mortality, especially in primary light chain (AL) amyloidosis 2017-04-13 · Amyloid deposition (amyloidosis) is a systemic disease that is rare in B6C3F1, BALB/c, and C3H/HeJ mice and in rats but is common in CD-1, A, Swiss Webster, SJL, and C57BL/6 mice. In B6C3F1 mice, vascular deposits can be limited to a single tissue (e.g., jejunum, pancreas, testis).

Amyloid protein– SAA (serum amyloid A). Pathogenesis– Long-standing inflammatory disorders or infections (rheumatoid arthritis, familial Mediterranean fever (FMF), inflammatory bowel disease, and chronic infections) lead to overproduction of SAA, an apolipoprotein that is an acute-phase reactant. Another type of ATTR amyloidosis is not hereditary. This is called wild-type ATTR amyloidosis, or senile systemic amyloidosis. In this condition, the amyloid deposits mainly affect the heart and can also cause carpal tunnel syndrome in some people.
