Global longitudinal strain analysis. Global longitudinal strain is -7% in this patient, and the polar map shows a characteristic apical sparing pattern consistent with cardiac amyloidosis. ANT, anterior; ANTS, anteroseptal; INFS, inferoseptal; INF, inferior; INFL, inferolateral; ANTL, anterolateral

FIG2
Echocardiography showed ejection fraction of 36%, septal thickness of 1.3 cm, and reduced global longitudinal strain with a characteristic apical sparing pattern (Figure 2).

Cardiac magnetic resonance imaging (MRI). A diffuse subendocardial late gadolinium enhancement pattern is noted in the short axis (A) and four-chamber (B) images on this cardiac MRI. The arrows point to the white subendocardial stripe of late gadolinium enhancement in the anterolateral wall

FIG3
Echocardiogram showed ejection fraction of 35% and septal thickness of 1.8 cm, and cardiac magnetic resonance imaging (MRI) showed diffuse subendocardial late gadolinium enhancement consistent with amyloidosis (Figure 3).

Electrocardiogram. A 12-lead electrocardiogram demonstrating normal sinus rhythm with diffuse low voltage, incomplete right bundle block, and a pseudoinfarct pattern in anterior and inferior leads. aVR, augmented vector right; aVL, augmented vector left; aVF, augmented vector foot

FIG4
Electrocardiogram showed sinus rhythm with first-degree atrioventricular (AV) block and diffusely low voltage (Figure 4).
