Amyloidosis is a rare systemic disease due to the extracellular tissue deposition of a fibrillar-shaped misfolded protein, called amyloid. Only two types of proteins commonly affect the heart leading to an infiltrative cardiomyopathy: immunoglobulin light chain and transthyretin (TTR) cardiac amyloidosis (CA).

Cardiac ATTR, though infrequently diagnosed during lifetime, may represent a prevalent cause of RCM, especially in elderly. Cardiac amyloidosis is a subcategory of amyloidosis where there is depositing of the protein amyloid in the cardiac muscle and surrounding tissues. Amyloid, a misfolded and insoluble protein, can become a deposit in the heart’s atria, valves, or ventricles. Nuclear scintigraphy offers comparable performance in diagnosing cardiac amyloidosis but can also reliably differentiate ATTR from AL amyloidosis affecting the heart, when combined with a monoclonal protein screen. Heart transplantation For hereditary ATTR amyloidosis, combined heart and liver transplant has been performed in a few dozen cases around the world. This operation is only an option for a very small minority of patients, and it carries significant risks.

(-) monoclonal protein, (+) scintigraphy scan: if grade 2 or 3 uptake on the scan then this is diagnostic for ATTR cardiac amyloidosis and no biopsy is needed, if grade 1 uptake then will need a biopsy to confirm diagnosis. Technetium-labeled cardiac scintigraphy (i.e., Tc-PYP scan) has been repurposed for the diagnosis of transthyretin amyloid cardiomyopathy (ATTR-CM). Validated in cohorts of patients with heart failure and echocardiographic and/or cardiac magnetic resonance imaging findings suggestive of cardiac amyl … Several scintigraphic tracers allow the visualization of amyloid deposits, but the most used are the bone tracers (99mTc-DPD, 99mTc-HMPD, 99m Tc- MPD, 99m Tc-PYP) . They bind to cardiac amyloid deposits with a very good sensitivity for transthyretin amyloidosis (hereditary or senile), while AL amyloidosis absorbs these tracers only slightly.
