Elbdri S, Hajar R. Cardiac amyloidosis. Heart Views 2021;22:231-2
Amyloidosis is due to the deposition of amyloid fibrils in various organs. If it affects the heart, it is known as "stiff heart syndrome." The predominant morphologic feature in the heart is an increase in myocardial wall thickness (>15 mm) without dilatation of the left ventricular (LV) cavity. This can usually be seen on echocardiography and is the hallmark of cardiac amyloidosis [Figure 1].

Amyloid deposits in the heart are diffuse and may involve the valves, myocardium, interatrial septum, and pericardium. Other conditions may produce similar echocardiographic features. Patients with cardiac amyloidosis usually have a low QRS voltage [Figure 2] or a pseudoinfact pattern on electrocardiogram (ECG). Pulse-wave Doppler inflow through the mitral shows severe diastolic dysfunction or restriction [Figure 3].

The above images belong to a female patient who was 80 years old and admitted with decompensated heart failure for which she was being treated for the last 2 years. She also was being treated for hypertension and dyslipidemia. She had numbness of fingers and symptoms similar to those of carpal tunnel syndrome. Her ECG showed low QRS voltage and her echo showed concentric LV hypertrophy with the restrictive pattern on pulsed-wave Doppler tracing of the mitral valve. These are enough data to provide comprehensive morphologic, functional, and prognostic information. She also had carpal tunnel syndrome, and amyloidosis is known to be associated with it, because of amyloid deposition in the tendon.
