case_images: Her cardiac echocardiogram showed a normal left ventricular size measuring 4.9 cm, low-normal left ventricular ejection fraction (50%), elevated right atrial pressure (dilated inferior vena cava, with respiratory size variation less than 50%), and left ventricle lateral wall abnormality (Figure 4;. https://www.youtube.com/watch?v=soLXgVLXppU).
