Cardiac Abnormalities in Acromegaly Patients: A Cardiac Magnetic Resonance Study

Figure 1

Typical cardiac abnormalities in acromegaly patients evaluated by cardiac magnetic resonance imaging. (a) Interventricular septum (IVS) hypertrophy and left ventricular (LV) hypertrophy shown. (b) Normal IVS thickness and LV mass index. The red lines shown in (a) and (b) indicate the lines along which IVS thickness was measured, and the areas surrounded by green lines reveal the LV mass used for calculations. (c) LV and right ventricular (RV) systolic dysfunction at end-diastolic stage. (d) LV and RV systolic dysfunction at end-systolic stage. The images shown in (c) and (d) were recorded from the same patient. The red area represents the LV volume, and the blue areas represent the RV volume. (e) Mid-wall late gadolinium enhancement (LGE) of the IVS myocardium (red arrow “1”) and the LV myocardium on the cardiac short axis (red arrow “2”). (f) Mid-wall LGE of the basal anterior LV myocardium on the cardiac long axis (red arrow “3”).
