Abstract
BACKGROUND: Carpal tunnel syndrome (CTS) is considered an early sign of cardiac amyloidosis (CA) because amyloid deposition is often confirmed in the tenosynovium removed during carpal tunnel release (CTR); however, the prevalence of concomitant CA is unclear. METHODS AND RESULTS: Tc-PYP scintigraphy and were diagnosed with wild-type transthyretin CA. Concomitant CA was observed in 6/120 (5%) CTR patients with amyloid deposition and 50% (6/12) in patients with left ventricular hypertrophy (≥12 mm) with increased hs-cTnT levels. CONCLUSIONS: Amyloid deposition was frequently observed in the removed tenosynovium of elderly men with CTS. Cardiac screening may be useful for early diagnosis of CA in patients undergoing CTR with amyloid deposition.
