Study methodology algorithm. A total of 197 patients underwent TAVR from 2019 to 2020 at our institution. There were 37 patients who were deceased on chart review. There were 105 patients who had the presence of high-risk features for ATTR. We attempted to contact these patients but were unable to contact 46 patients after multiple attempts. Of the 59 patients we were able to contact, 44 patients agreed to the referral to an advanced heart failure cardiologist. Twenty patients completed diagnostic tests; all were negative for ATTR or AL amyloidosis.

AS: aortic stenosis; ATTR: transthyretin cardiac amyloidosis; TAVR: transcatheter aortic valve replacement.
