ECHOCARDIOGRAPHIC PREDICTORS OF TRANSTHYRETIN CARDIAC AMYLOIDOSIS

Transthyretin cardiac amyloidosis (TTR-CA) is an under-recognized cause of heart failure. Technetium pyrophosphate (PYP) scintigraphy provides a method of diagnosing TTR-CA non-invasively while transthoracic echocardiography (TTE) is often the imaging modality that first raises the suspicion of TTR-CA. We aimed to compare the clinical and echocardiographic characteristics of patients with TTR-CA versus those with suspected but no TTR-CA among patients who underwent PYP scans.
