99m-technetium pyrophosphate (Tc-PyP) single-photon emission computed tomography (SPECT) is increasingly used to diagnose cardiac amyloidosis (CA)
1. A heart-to-contralateral (H/CL) ratio of >1.5 has been reported to be specific and sensitive in diagnosing transthyretin (TTR) CA
2. We present two cases in which SPECT imaging revealed a low H/CL in the setting of a prior infarct. …
