Evaluating aortic stenosis with echocardiography requires a comprehensive view of how the heart adapts to the narrowed valve, not just the valve itself. The afterload from AS drives the left ventricle to change its structure and function, so you assess LV size and geometry, how well the ventricle pumps (systolic function), and how well it relaxes and fills (diastolic function). Systolic function may stay preserved until late, while diastolic dysfunction often develops due to concentric LV hypertrophy, so parameters like EF, global longitudinal strain if available, E/A and E/e’ ratios, and LA size provide important clues about filling pressures and overall function. At the same time, it’s crucial to estimate any associated valve lesions because AS often coexists with aortic regurgitation or other valvular diseases that influence prognosis and management. You also assess the aortic root diameter since aortopathy can accompany valvular disease, especially with bicuspid valves. This broad assessment—LV size, systolic and diastolic function, and estimation of associated valve lesions—gives the complete picture. The other options are too limited, omitting either parts of LV function or concomitant valvular pathology.
