Abstract
In recent years, there has been a significant increase in diagnosed cases of patients with transthyretin amyloidosis (ATTR) of the heart, predominantly with the acquired form of ATTR, also referred to as wild-type ATTR (wtATTR). This is due to the possibility of non-invasive diagnosis of ATTR based on the combination of a clearly positive finding of scintigraphic examination using technetium-labelled bisphosphonates (most often DPD scintigraphy) and a negative result of laboratory tests for AL amyloidosis.
It turns out that wtATTR is not a rare cause of heart failure or arrhythmias, particularly of conduction disorders and atrial fibrillation, in elderly patients. The aim of this article is to provide an overview of the clinical manifestations, diagnostic process, and therapeutic options for ATTR, including its specific treatment.
