The actual scenario of pharmaceutical approaches for ATTRv amyloidosis includes five main groups: TTR stabilizers, TTR mRNA silencers, TTR fibril disruptors, inhibitor of TTR fibril seeding and gene therapy. Patisiran is a small, double-stranded interfering RNA encapsulated in a lipid nanoparticle, able to penetrate into hepatocytes, where it selectively targets TTR mRNA, reducing TTR production. We report and discuss 9 cases of different patients with ATTRv amyloidosis successfully managed with patisiran in the real clinical practice. Literature data, as well as the above presented case reports, show that this drug is effective and safe in improving both neurological and cardiovascular symptoms of ATTRv amyloidosis, and to maintain a good QoL, independently form the stage of the disease and the involved mutation. Recent studies correlated improved functional and biochemical outcomes with a regression of amyloid burden, especially at the cardiac level. Today, patisiran can be considered a valid therapeutic option for the management of patients with ATTRv amyloidosis and polyneuropathy and cardiovascular symptoms.Keywords: hereditary transthyretin amyloidosis, patisiran, real-life, case reports
