Bokhari S, Castaño A, Pozniakoff T, Deslisle S, Latif F, Maurer MS. 99m Tc-Pyrophosphate scintigraphy for differentiating light-chain cardiac amyloidosis from the transthyretin-related familial and senile cardiac amyloidosis. Patients with suspect cardiac amyloidosis without monoclonal components can have an attempted nonbiopsy diagnosis of ATTR amyloidosis with cardiac scintigraphy with bone tracers. Validated tracers are 99m Tc-diphosphono-propanodicarboxylic acid, 99m Tc-pyrophosphate, and 99m Tc-hydroxymethylene diphosphonate.

Bone scintigraphy (paired with exclusion of serum free light chains) is emerging as the technique of choice for distinguishing ATTR from light chain cardiac amyloidosis and other cardiomyopathies; it has transformed the diagnostic pathway for ATTR, allowing noninvasive diagnosis of ATTR without the need for a tissue biopsy in the majority of patients. 2020-01-09 · Bone Scintigraphy Imaging for Transthyretin Cardiac Amyloidosis: Still Much to Learn. Alexander KM(1), Witteles RM(2). Author information: (1)Stanford Amyloid Center, Division of Cardiovascular Medicine, Stanford University School of Medicine, Stanford, California; Stanford Cardiovascular Institute, Stanford University School of Medicine, Stanford, California. Cardiac amyloidosis is a disease in which misfolded proteins aggregate into amyloid fibrils and deposit into the heart, leading to predominantly diastolic heart failure and ultimately death.1Nuclear imaging with technetium-99 m pyrophosphate (TcPYP) has evolved since the initial description in patients with myocardial infarction to reliably detect transthyretin type (ATTR) cardiac amyloidosis.

PYP stands for pyrophosphate. 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.

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.

• A distinct advantage of 99mTc-PYP imaging, even when echocardiography and CMR are diagnostic for cardiac amyloidoisis, is its ability to specifically identify ATTR cardiac amyloidosis non-invasively Cardiac amyloidosis can form part of a systemic disease and coexist with the involvement of other organs or, more rarely, can involve principally the heart. When it affects the heart, it usually presents as restrictive cardiomyopathy, which leads to death due to heart failure in the majority of the patients.

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). 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.

The radiotracer 99mTc-pyrophosphate (99mTc-PYP) binds to deposited ATTR amyloid fibrils in the myocardium and can be visualized using planar and SPECT imaging. Validated in cohorts of patients with heart failure and echocardiographic and/or cardiac magnetic resonance imaging findings suggestive of cardiac amyloidosis, cardiac scintigraphy can confirm the diagnosis of ATTR-CM only when combined with blood and urine testing to exclude a monoclonal protein. 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) [ 1 ]. 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. Several case reports and larger studies dating back to the 1980s have described the utility of 99m Tc-PYP, as used in this study, in identifying cardiac amyloidosis. 2,25 – 32 However, 99m Tc-PYP scintigraphy has not yet been established for the noninvasive evaluation of cardiac amyloidosis for several reasons: results to date have been in large part conflicting and with variable sensitivity; amyloid subtype was not defined in many of the early studies and those that defined it were Background.
