An 88-year-old man was referred for consideration of transcatheter aortic valve implantation (TAVI) to treat severe aortic stenosis (AS). Transthoracic echocardiography confirmed severe AS, but also showed disproportionate left ventricular hypertrophy, with restrictive diastology and impaired global longitudinal strain, with an apical sparing pattern. In view of these echocardiographic appearances and a history of bilateral carpal tunnel decompressions, the patient was referred for 99mTc-3,3-diphosphono-1,2-propanodicarboxylic

acid (DPD) scintigraphy prior to TAVI, which revealed Perugini Grade 2 cardiac uptake diagnostic of cardiac amyloidosis. Extracellular volume (ECV) quantification was also performed, as part of the TAVI work-up computed tomography (CT), using a single 3-min post-contrast acquisition. The ECV was elevated (base 51 ± 4%, mid 46 ± 5%, apex 41 ± 5%), consistent with cardiac amyloidosis.
