Background: Cardiac amyloidosis results from the deposition of amyloid fibrils in the myocardial extracellular matrix, leading to restrictive cardiomyopathy and heart failure. Diagnosis has traditionally been challenging owing to non-specific clinical features and reliance on endomyocardial biopsy. Advances in cardiova...
