Official title
Retrospective Identification of Scintigraphic Cardiac Amyloidosis Using Deep Learning-based Model
Overview
This study aims to determine the positive predictive value of incidental cardiac uptake on bone scintigraphy for diagnosing transthyretin cardiac amyloidosis, in patients who underwent scintigraphy for reasons other than suspected amyloidosis. The study is an observational, descriptive, multicenter, national study using retrospective data from routine care. Patients with incidental cardiac uptake will be recalled for further diagnostic assessment.
Primary outcome measures
- Cardiac amyloidosis diagnosis [Time frame: After the reassessment evaluation (one-day evaluation)]
Eligibility criteria
Inclusion criteria
- Adults (≥ 18 years)

- Incidental cardiac uptake (Perugini grade ≥2) confirmed by a nuclear medicine specialist
Exclusion criteria
- Patients under legal protection
- Patients refusing the reuse of their data after individual information
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
