The cardiac size is normal, but the left atrial appendage is prominent (LAA in the annotated image below). Main pulmonary artery (MPA) segement is just outside the left border, indicating pulmonary hypertension. The enlargement of left pulmonary artery (LPA) and right pulmonary artery (RPA) are just modest, if at all. The horizontal fissure is visible, indicating collection of edema fluid in the fissure. The aortic knuckle (Ao) is also seen well. There is suggestion of Kerley B lines near the costophrenic angles, but not typical.
