99m Tc‐DPD scintigraphy is a useful imaging modality to detect amyloid in these rare sites and might also be useful for serial imaging. This technique is particularly useful in patients with IgM‐related AL amyloidosis, in which soft tissue amyloidosis accounts for 35% of patients, of whom 20% have LN amyloidosis (Sachchithanantham et al, 2016).

Tc-99m-DPD scintigraphy is a highly sensitive method for diagnosing heart involvement in ATTR amyloidosis. The objective of this study was to determine the relationship between ATTR fibril composition and Tc-99m-DPD scintigraphy outcome in patients with biopsy-proven ATTR amyloidosis. Transthyretin-related cardiac amyloidosis (ATTR) amyloidosis is an aggressive, rapidly progressive, and fatal disease, for which several promising therapies are in development. This condition is frequently underdiagnosed because of the limited specificity of echocardiography and the traditional requirement for histological diagnosis. Heart-to-skull retention was linked to levels of cardiac amyloidosis. Patients with a lower heart-to-skull score experienced a better rate of survival, free of major cardia events, at six months 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).

Background. Structure of the SAP molecule, reproduced from Nature 367, 338 – 345 (27 January 1994) In 1987 Sir Mark Pepys invented a completely new test for amyloidosis called SAP scintigraphy or SAP scanning and Professor Philip Hawkins developed it for routine clinical use. This technique shows the distribution and amount of amyloid in the organs throughout the body without the need for biopsies, which can only sample a microscopic amount of tissue from a limited number of places.

Presented by Scott Jerome, DO, FACC, FASNC, FSCCT, this webinar is designed to: illustrate the importance of quality images for optimal cardiac amyloidosis i Semi-quantitative evaluation by heart to whole body profile proved to be the most accurate ratio in determining cardiac amyloidosis by scintigraphy. Differentiating ATTR from other types of CA, or from normal population, based on myocardial uptake was emphasized by Ramsay et al. by quantifying the role of 99m Tc-HDP quantitative SPECT/CT in assessing a reference interval. [26] Cardiac amyloidosis is a multi-organ syndrome, which usually presents as restrictive cardiomyopathy (RCM).

A cardiac PYP scan uses a radioactive form of PYP called Tc99m-PYP. Why is the scan Cardiac amyloidosis is a form of restrictive cardiomyopathy caused by the accumulation of misfolded proteins, amyloid fibrils, within the myocardium.

(-) monoclonal protein, (-) scintigraphy scan: unlikely to have cardiac amyloidosis, consider cardiac MRI and possible biopsy if suspicion is still high. (-) 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.

Transthyretin (TTR) amyloidosis (or ATTR) is a subtype of amyloidosis which frequently involves heart. Cardiac ATTR, though infrequently diagnosed during lifetime, may represent a prevalent cause of RCM, especially in elderly.

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.

Further studies are necessary for the standardization of imaging protocol and development of non-invasive diagnostic tools, especially in assessing the response to treatment and disease progression, for which little is known.
