A: Two dimensional echocardiogram in a patient with amyloidosis showing thick ventricles, dilated atria, thick interventricular septum and a pericardial effusion. Left ventricular systolic function is depressed.

B: Strain echocardiography showing relatively preserved longitudinal strain in the apex (red) compared to the mid and basal myocardial segments. More negative values on the color scale depicts regions with normal longitudinal strain.

Director: Prem Soman, MD, PhD

Tc-99m pyrophosphate (PYP) scintigraphy:

Tc-99m PYP is a bone scan agent. It is normally not taken up by the myocardium. (Left Panel). Avid myocardial uptake is diagnostic of cardiac ATTR amyloidosis (Right Panel).


Cardiac Magnetic Resonance Imaging

Director: Eric B. Schelbert, MD, MS


Left Panel: Characteristic cardiac magnetic resonance (CMR) image showing thick ventricles, decreased longitudinal excursion of the myocardium, thickened interatrial septum and dilated atria. Right Panel: Gadolinium enhancement shows diffuse delayed enhancement of the myocardium and rapid clearance of gadolinium from the blood pool.
