Vutrisiran Treatment and Cardiovascular MRI-Detected Changes in Cardiac Structure, Function, and Amyloid Burden in ATTR-CM

MedXY Editorial Team•Aug 13, 2026•Cardiology

Vutrisiran therapy leads to significant improvements in biventricular systolic function and reductions in left ventricular mass in patients with transthyretin amyloid cardiomyopathy (ATTR-CM).
Cardiovascular magnetic resonance (CMR) imaging with extracellular volume (ECV) mapping enables sensitive, noninvasive tracking of cardiac amyloid burden and treatment-related regression.
Post hoc analysis of the UK HELIOS-B cohort demonstrates that vutrisiran associates with amyloid regression in a subset of patients and markedly reduces amyloid progression compared to placebo over three years.
Echocardiographic secondary outcomes corroborate structural and functional cardiac benefits, underscoring vutrisiran’s impact on clinical outcomes.
