Brief Summary: This study intends to conduct a prospective observation to investigate the prevalence of cardiac amyloidosis (CA) in patients with aortic stenosis (AS), compare the clinical characteristics between patients with isolated AS and those with AS complicated by CA (CA-AS), and simultaneously explore the impact of transcatheter aortic valve replacement (TAVR) on serum transthyretin (TTR) levels in patients with AS complicated by transthyretin amyloidosis (ATTR-AS), as well as its influence on the treatment outcomes of patients with isolated AS and ATTR-AS....
