Technetium-99m-labelled 3,3-diphosphono-1,2-propanodicarboxylic acid ( 99m Tc-DPD) is a sensitive method for imaging cardiac transthyretin (ATTR) amyloid. We report utility and limitations of 99m Tc-DPD scintigraphy in 321 patients with suspected cardiac amyloidosis. Methods and results.

12,15–17 Older autopsy studies have shown cardiac ATTR amyloid 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). 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. [26] Cardiac amyloidosis is a multi-organ syndrome, which usually presents as restrictive cardiomyopathy (RCM).
Cardiac amyloidosis is a disorder caused by amyloid fibril deposition in the extracellular space of the heart [ 1 ]. This topic will review the clinical manifestations, natural history, and diagnosis of amyloid cardiomyopathy. The treatment of amyloid cardiomyopathy and an overview of amyloidosis is discussed separately. In older men with an echocardiogram consistent with cardiac amyloidosis, a technetium scintigraphy showing uptake of ⁹⁹ᵐTc-PYP or ⁹⁹ᵐTc-DPD in myocardial tissue increases the suspicion of wild-type TTR (ATTRwt) amyloidosis.

The Clinical Features of immunoglobulin light-chain (AL) amyloidosis with heart involvement. QJ Med. 1998;91(2):141-157; Sayed RH et al. A study of implanted cardiac rhythm recorders in advanced cardiac amyloidosis with cardiac involvement. Eur heart J. (2015) 36, 1098-1105. 99m Tc-DPD scintigraphy is probably positive in all patients with clinically significant cardiac ATTR amyloidosis; however, it is not completely specific for this condition and cardiac localisation does occur in a small proportion of patients with advanced cardiac AL amyloidosis and cardiac ApoA1 amyloidosis.

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

• 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. 4.
