CARDIAC STRUCTURE | FINDINGS |
---|---|
Left ventricle | Concentric left ventricular hypertrophy Binary septum (low sensitivity and specificity for FD) Prominent papillary muscles Preserved LV function until end-stages Diastolic dysfunction Abnormal global longitudinal or radial strain, even in the absence of LVH |
Right ventricle | Right ventricular hypertrophy Preserved RV function until end-stages Abnormal global longitudinal strain even with preserved EF |
Atrium | Biauricular dilation Increased end-diastolic pressure Reduced auricular strain |
Valves | Increase in mitral and aortic valve thickness Valvular regurgitation (generally, mild) |
Aorta | Dilation of the aortic root and the ascending aorta (not descending aorta) |
