Representative images of patients with transthyretin amyloid cardiomyopathy (ATTR‐CM). (A) Heart failure with pulmonary congestion and pleural effusion, (B) carpal tunnel syndrome (CTS) with thenar muscle atrophy (red arrows) and numbness in the thumb to the thumb side of the ring finger (area served by the median nerve), (C) electrocardiogram with low voltage (red box) and pseudo‐infarct pattern (blue box), (D) cardiac hypertrophy [left ventricular hypertrophy (LVH) with granular sparkling] on echocardiography, (E) apical sparing on echocardiography, (F) cardiac magnetic resonance (CMR) with subendocardial late gadolinium enhancement (LGE). A ring‐shaped subendocardial contrast is observed, consistent with the endocardium. The septal site has transmural enhancement (arrow), and the right ventricle also shows contrast enhancement.
