isolated cardiac amyloidosis. utility of bone seeking tracers scintigraphy in differentiating the subtype of amyloid: a case report

Three types of amyloid are responsible for cardiac amyloidosis. differentiation of the subtype is critical for the disease progression and the therapeutic decision. myocardial scintigraphy using tc-pyp is able to differentiate the cardiac amyloid subtype with high sensitivity and specificity. the myocardial uptake of pyp is higher in patients with ttr amyloidosis. non-invasive tests for the detection of cardiac amyloidosis, like myocardial scintigraphy with bone seeking tracers, can play a major role in the diagnosis progression and therapeutic management of patients with cardiac amyloidosis.
