Wild‐type transthyretin cardiac amyloidosis and aortic stenosis: Can carpal tunnel syndrome help distinguish the chicken from the egg?

Background The frequent association between transthyretin wild‐type (TTRwt) cardiac amyloidosis (CA) and aortic stenosis (AS) suggests a bidirectional relationship: TTRwt‐CA could induce AS and vice versa. Systemic manifestations may highlight this interaction: systemic amyloidogenesis would lead to...

Zusammenfassung:Background The frequent association between transthyretin wild‐type (TTRwt) cardiac amyloidosis (CA) and aortic stenosis (AS) suggests a bidirectional relationship: TTRwt‐CA could induce AS and vice versa. Systemic manifestations may highlight this interaction: systemic amyloidogenesis would lead to systemic symptoms, CA, and AS, whereas the myocardial stresses induced by degenerative AS might promote local amyloidogenesis without systemic symptoms. Carpal tunnel syndrome (CTS) is the most frequently reported extracardiac symptom. Through a comparison of TTRwt‐CA patients with and without CTS, we sought to determine whether CTS serves as a reliable indicator of systemic involvement and its impact on cardiac and valvular characteristics. Methods and results A total of 411 consecutive patients with TTRwt‐CA were included. CTS, present in 70.3%, was associated with a younger age (80 vs. 84 years, p
