Prognostic impact of suspected cardiac amyloidosis in aortic stenosis patients referred for transcatheter aortic valve implantation

Background The prevalence of cardiac amyloidosis (CA) and aortic stenosis (AS) both increase with age. Transcatheter aortic valve implantation (TAVI) expands the number of patients (P) eligible for treatment of AS, emphasizing the need to understand the prevalence of CA in AS and its prognostic associations. Echocardiography with speckle tracking has emerged as a useful method to enhance the clinical suspicion and to provide prognostic...
