Pre-treatment TTE: Apical 4 chamber (A4C) view in systole showing reduced LV systolic function.A: Left ventricle visually appears dilated in this still image suggestive of impaired function in systole;B: The right ventricle visually appears to be contracting maximally in this still image, suggestive of normal function in systole;C: Both atria appear to be normal in size in this still image.TTE: Transthoracic echocardiogram; LV: Left ventricular.
