Abstract: Background ATTR cardiac amyloidosis (CA) can be diagnosed with Tc-99m-PYP scintigraphy. There are two recommended interpretative approaches: the quantitative heart-to-contralateral lung ratio (H/CL) at 1 hour and the semi-quantitative visual system at 3 hours. This… read more here.

Abstract: Two distinct types of systemic amyloidosis-transthyretin (ATTR) and light chain (AL)-account for the majority of cardiac amyloidosis (CA), which have been considered mutually exclusive. Diagnostic confusion can arise when both proteins are identified from an… read more here.
