Subthreshold Aortic Valve Calcium Scores in Severe Aortic Stenosis and Transthyretin Cardiac Amyloidosis

We have clinically observed that some patients with transthyretin cardiac amyloidosis and severe aortic stenosis may have lesser degrees of calcification than one might expect. We report a case series of 3 patients with transthyretin cardiac amyloidosis and severe aortic stenosis despite discordant aortic valve calcium scores. (Level of Difficulty: Intermediate.).
