Association Between Ruptured Distal Biceps Tendon and Wild-Type Transthyretin Cardiac Amyloidosis

Figure.. Examples of Ruptured Biceps Tendon in 2 Patients With Biopsy-Proven ATTRwt Cardiac Amyloidosis

ATTRwt indicates wild-type transthyretin amyloidosis. A, Patient with prior rupture of the biceps tendon and bunching of the biceps with flexion. B, Patient with acute rupture of the biceps tendon in the left arm. The tendon rupture occurred with trivial trauma, 5 years after cardiac amyloid diagnosis.
