Background: The amyloidoses are a rare and heterogeneous group of disorders that are
characterized by the deposition of abnormally folded proteins in tissues ultimately leading to …

Cardiac amyloidosis (CA) is related to the aggregation of insoluble fibrous deposits of
misfolded proteins within the myocardium. Transthyretin amyloidosis (ATTR) and …

Cardiac amyloidosis is one form of systemic amyloidosis caused by abnormal amyloid fibrils
deposited in the extracellular space of the myocardium causing heart failure because of …

Background: Atrial arrhythmia (AA) is common among patients with cardiac amyloidosis
(CA), who have an increased risk of intracardiac thrombus. The aim of this study was to …

Left-to-right differences in the histopathologic patterns of transthyretin-derived amyloid
(ATTR) deposition in the atria of older adults have not yet been investigated. Hence, this …

Cardiac involvement is the most important factor determining prognosis in patients with
systemic amyloidosis. This retrospective observational study of 98 patients with amyloidosis …

Amyloidosis is a broad class of diseases all of which result in deposition of misfolded
extracellular protein that result in organ dysfunction. Once considered a rare condition …

Background Recent studies have reported atrial involvement and coexistence of aortic
stenosis in transthyretin (ATTR) cardiac amyloidosis (CA). However, pathological reports of …

Atrial amyloidosis is primarily caused by atrial natriuretic peptide (ANP) amyloid deposition.
The main precursor protein causing cardiac amyloidosis is transthyretin (TTR), also known …
