Figure 1 Imaging examinations during the first hospitalization. A: Right ventricular enlargement (29 mm) and thickened right ventricular wall (9 mm); B: Dilated pulmonary artery (28 mm); C: Shortening of pulmonary artery forward blood flow spectrum acceleration time (74 ms). The spectrum form was "fist indication" with visible incisure; D: Mild aortic stenosis (V_max = 336 cm/s; pressure gradient = 45 mmHg); E: Moderate aortic insufficiency; F: Computed tomography angiography showing pulmonary artery branch embolism (arrow denotes a filling defect).
