Novel Parametric T1-mapping on Cardiovascular Magnetic Resonance versus DPD Imaging to Monitor Response to Therapy in Transthyretin Amyloid Cardiomyopathy

Transthyretin amyloid cardiomyopathy (ATTR-CM) is an increasingly-recognised disease characterised by progressive accumulation of misfolded protein fibrils. It manifests as an infiltrative cardiomyopathy with increased myocardial wall thickness, conduction disease, heart failure, and poor prognosis.

Novel cardiovascular magnetic resonance (CMR) imaging biomarkers such as parametric mapping are highly promising for quantitatively assessing disease burden in patients with ATTR-CM. This project will explore novel and conventional imaging biomarkers for monitoring disease progression and response to treatment in ATTR-CM patients. Quantitative imaging biomarkers that reliably track treatment effects have multiple clinical applications across the spectrum of cardiovascular disease, including potential to inform guidelines, therapeutic regulations, and future clinical trial design in the rapidly evolving field of novel targeted therapies.
