Abstract:
PURPOSE:We previously reported in a small series of patients that (99m)Tc-3,3-diphosphono-1,2-propanodicarboxylic acid ((99m)Tc-DPD) scintigraphy tested positive in transthyretin-related (TTR) (both mutant and wild-type) but not in primary (AL) amyloidotic cardiomyopathy (AC). We extended our study to a larger cohort of patients with AC. METHODS:We evaluated (1) 45 patients with TTR-related AC (28 mutant and 17 wild-type), (2) 34 with AL-related AC and (3) 15 non-affected controls. Myocardial uptake of (99m)Tc-DPD (740 MBq i.v.) was semiquantitatively and visually assessed at 5 min and at 3 h. RESULTS:Heart retention (HR) and heart to whole-body retention ratio (H/WB) of late (99m)Tc-DPD uptake were higher among TTR-related AC (HR 7.8%; H/WB 10.4) compared with both unaffected controls (HR 3.5%; H/WB 5.7; p < 0.0001) and AL-related AC (HR 4.0%; H/WB 6.1; p < 0.0001). For the diagnosis of TTR-related AC, positive and negative predictive accuracy of visual scoring of cardiac retention were: 80 and 100% (visual score ≥1); 88 and 100% (visual score ≥2); and 100 and 68% (visual score = 3). At adjusted linear regression analysis, TTR aetiology turned out to be the only positive predictor of increasing (99m)Tc-DPD uptake in terms of both HR [β 2.5, 95% confidence interval (CI) 1.5-3.5; p < 0.0001] and H/WB (β 3.5, 95% CI 2.1-4.9; p < 0.0001). CONCLUSION:While (99m)Tc-DPD scintigraphy was confirmed to be useful for differentiating TTR from AL-related AC, diagnostic accuracy was lower than previously reported due to a mild degree of tracer uptake in about one third of AL patients. (99m)Tc-DPD scintigraphy can provide an accurate differential diagnosis in cases of absent or intense uptake evaluated by visual score.
