Amyloidosis and Thoracic Aortic Disease: A Scoping Review
Abstract
Background and Objectives: Amyloidosis is a systemic disorder characterized by extracellular deposition of misfolded protein fibrils, most commonly light-chain (AL) or transthyretin-derived (ATTR) ones. Cardiac involvement is well recognized, but large-vessel complications, including thoracic aortic aneurysms (TAA) and dissections, are rare and under-reported. The aim of this review article is to provide insights into pathophysiology, clinical diagnosis and the therapeutic opportunities in amyloidosis-related thoracic aortic diseases. Methods and Materials: The PRISMA Extension for Scoping Reviews (PRISMA-ScR) Guidelines were followed. An extensive search of the available literature in the English language, published between 1 January 2000, and 31 December 2025, in three large-scale scientific databases was undertaken by two independent reviewers. The terms "amyloidosis", "thoracic aorta", "thoracic aortic aneurysm", "aortic dissection", and "aortopathy" were used both as specific items, as well as in MeSH Terms. Studies reporting on the pathophysiology, diagnosis, clinical manifestations, treatment options and prognosis of amyloid deposition on the thoracic aorta were included in the review. Because of the nature of the existing literature, only a narrative review was possible. Results: Twenty-nine studies were included. Owing to the rarity of reporting, data was derived mainly from case reports and series, as well as autopsy studies. Amyloid infiltration of the aortic wall…
