Diagnostic and prognostic value of cardiac imaging in amyloidosis

Figure 1 Algorithm for diagnostic patients with suspected cardiac amyloidosis[78]. AL: Light chain amyloidosis; ATTR: Transthyretin amyloidosis; ATTRv: Variant transthyretin amyloidosis; ATTRwt: Wild-type transthyretin amyloidosis; CA: Cardiac amyloidosis; ECG: Electrocardiogram.

Figure 2 Transthoracic echocardiography imaging from a patient with transthyretin amyloidosis-cardiac amyloidosis. A: Strain imaging by transthoracic echocardiography; B: Reduced mid and basal values with apical sparing.

Figure 3 Native T1-mapping images. Abnormally elevated values of T1 native (1120 ms) in a patient with amyloidosis-cardiac amyloidosis.
