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.

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.

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.

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. Several studies, have concluded that cardiac transthyretin amyloidosis can be reliably diagnosed in the absence of histology provided that all of the following criteria are met: heart failure with an echocardiogram or CMR that is consistent with or suggestive of amyloidosis, intense cardiac uptake on a 99m Tc labeled bisphosphonate bone scan, no detectable monoclonal protein in serum with normal serum-free light chains. AL amyloidosis is unlikely in any patient satisfying all the above criteria. Scintigraphy shows cardiac uptake and at least one of the monoclonal protein tests is abnormal.

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

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.

2017-03-01 · Negative myocardial technetium-99 m pyrophosphate scintigraphy in amyloid heart disease associated with type AA systemic amyloidosis Am J Cardiol , 53 ( 1984 ) , pp.

Thirty-four patients with amyloidosis proved by biopsy specimen were studied using technetium Tc 99m pyrophosphate scintigraphy to assess its utility in the diagnosis of amyloid heart involvement. Of 14 patients studied retrospectively, only three had intense uptake judged to be diagnostic of cardiac amyloidosis.

negative scintigraphy cannot eliminate AL amyloidosis [2]. Gillmore et al. have concluded that cardiac transthyretin amyloidosis can be reliably diagnosed in the absence of histology provided that all of the following criteria are met: Heart failure with an echocardiogram or cardiac magnetic resonance that is consistent with or suggestive of amyloidosis, grade 2 or 3 cardiac Bone scintigraphy presents promising results for identifying patients at early stages of disease and to differentiate between cardiac amyloidosis types. 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.
