The prevalence of ATTR-CA detected by scintigraphy in AS patients (8–13%) in the aforementioned studies was lower than the 25% reported in autopsy studies of individuals over 80 years of age, but this value is more realistic and indicates the most accurate diagnosis of amyloid cardiomyopathy compared to TTR deposition alone [5,15,41,55]. Here, TTR is linked to aortic stenosis.
