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).

av B Pilebro · 2017 — Background Hereditary transthyretin amyloid (ATTRm) amyloidosis is a systemic DPD scintigraphy, cardiac biomarkers, clinical data and

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. Supporting amyloidotic organ function Dubrey et al. The Clinical Features of immunoglobulin light-chain (AL) amyloidosis with heart involvement.

Methods and results.

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.

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.

Either 99mTechnetium diphosphonate (Tc-DPD) or pyrophosphate (Tc-PYP) scintigraphy plays a relevant role in diagnosing transthyretin cardiac amyloidosis (CA), and labeled radiotracers have been extensively studied in diagnosing CA. Few studies have analyzed and validated 99mTc-Hydroxymethylene diphosphonate (Tc-HMDP).

(-) 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. With the advent and optimization of nuclear scintigraphy protocols using bone-avid radiotracers, cardiac amyloidosis caused by transthyretin protein (ATTR) can now be diagnosed noninvasively without a costly tissue biopsy. The radiotracer 99mTc-pyrophosphate (99mTc-PYP) binds to deposited ATTR amyloid fibrils in the myocardium and can be visualized using planar and SPECT imaging.

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.

The cardiac MRI could not be performed because of claustrophobia. The 24h ECG Holter was normal. MIBG scintigraphy showed a normal uptake with a heart to mediastinum ratio of 2.4 (normal value >1.85). DPD "bone" scintigraphy showed a cardiac uptake with a Perugini grade 3 with a heart to lung ratio of 4, and attenuation of bone uptake.

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.
