Amyloidosis Tissue Confirmation for Tafamidis Eligibility Using Transverse Carpal Ligament and Tenosynovium Biopsy

      Summary

      In most Canadian provinces, eligibility criteria for public reimbursement coverage for tafamidis for treatment of transthyretin amyloidosis cardiomyopathy (ATTR-CM) include tissue biopsy confirmation of amyloidosis. Carpal tunnel syndrome requiring surgical release is common in ATTR-CM. We report our experience performing simultaneous transverse carpal ligament and tenosynovium biopsy during CTR, with all patients positive for amyloidosis, facilitating initiation of tafamidis.
