Background: Wild-type transthyretin amyloidosis (wtATTR) is an important cause of infiltrative cardiomyopathy in older adults. Carpal tunnel syndrome (CTS) is one of the most common extra-cardiac manifestations of wtATTR; however, the prevalence, severity, and risk of recurrence following carpal tunnel release (CTR) remain poorly understood. Methods: This retrospective cohort study reports findings from a single-centre experience of routine neurological screening of newly diagnosed wtATTR patients including nerve conduction studies. Consecutive wtATTR patients between 2014 and 2021 were included. Results: Seventy-nine wtATTR patients were included, 73 (92%) males, mean age of 79 years. Seventy-four (94%) had median neuropathy at the wrist (MNW), 50% having a prior diagnosis with the remaining 50% being diagnosed at screening. The majority with MNW were symptomatic (53, 67%) with moderate or severe disease (66, 84%) bilaterally (42, 53%) on electrophysiologic testing. Nineteen (24%) had recurrent CTS despite previous CTR. At the time of screening, 19 (24%) were prescribed wrist splinting and 36 (46%) were referred for CTR. Conclusions: Carpal tunnel syndrome is common in wtATTR. Most have bilateral disease with moderate to severe MNW at the time of wtATTR diagnosis. Recurrence of CTS after CTR is more common in wtATTR patients than in the general population.
