Tafamidis is a drug that improves the prognosis of transthyretin amyloid cardiomyopathy (ATTR-CM), but its primary effect is inhibition rather than improvement of amyloid deposition, making it difficult to assess therapeutic efficacy. The usefulness of monitoring treatment response using extracellular volume fractions (ECVs) with magnetic resonance imaging (MRI) has been reported, and we will perform a meta-analysis to evaluate the usefulness of this method.

Inclusion criteria
Inclusion criteria: Search Strategy and Selection Criteria Following the methodology proposed by the Cochrane Collaboration and adhering to the reporting criteria outlined in the 2020 Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines, we conducted a comprehensive database search using PubMed, Web of Science Core Collection, Cochrane advanced search, and EMBASE electronic databases. Use the following keywords: "tafamidis", "extracellular volume fraction", "extracellular volume", "ECV", "MRI", "cardiac MRI". Eligibility criteria present pre- and post-treatment MRI-ECV values for tafamidis and encompass all articles discoverable with the specified keywords. Exclusion criteria will be limited to case reports, animal studies, and non-English language articles.
