Figure 1.

Pulmonary angiography imaging findings. A: left pulmonary angiography showed no obvious filling defect, suggesting the pulmonary embolism of left pulmonary artery was ruled out; B: right pulmonary angiography showed no obvious filling defect, suggesting the pulmonary embolism of right pulmonary artery was ruled out.

Figure 2.

The echocardiography results. A: before treatment, the right heart was enlarged, the end-diastolic diameter of the right ventricle was 34 mm, the size of the right atrium was 56 mm×53 mm, the left heart was compressed, showing a “D” sign, and the pulmonary arterial pressure was 66 mmHg; B: normal echocardiography after treatment with a pulmonary artery pressure of 43 mmHg.
