Trans-thoracic echocardiography (Figure 1.1) revealed severe RV dilation and moderate RV dysfunction with moderate tricuspid regurgitation and elevated pulmonary artery systolic pressure (pulmonary artery systolic pressure (PASP): 45 mmHg). A chest computed tomography (CT) scan showed a wedge consolidation in left lower lobe of lung (Figure 1.2 left). According to the above findings, PE was diagnosed for the patients and chest CT angiography was done, which demonstrated a large filling defect in main pulmonary artery and both main bronchi (Figure 1.2 right). In brain CT scan, hemorrhagic transformation in territory of prior CVA was reported (Figure 1.3 left). Pulmonary CT angiography was done 24 hours after treatment and showed reduction of thrombus bulk and RV size (Figure 1.4). Two control brain CT scans (4 h and 24 h after treatment) didn't show any new intracranial hemorrhage (figure 1.3 right).

The findings of CT angiography (figure 2.1) confirmed Saddle embolism in pulmonary arteries (filling defects in main, left and right pulmonary artery).

The initial electrocardiogram showed sinus tachycardia at a rate of 135 per minute, right bundle branch block with a QRS duration of 125 milliseconds and right axis deviation of 120 degrees (figure 3.1). Pulmonary CT angiography confirmed large bilateral pulmonary thromboembolic (saddle-shaped embolism with obstruction of 85% of the arterial substrate) with radiological evidence of RV strain (figure 3.2).  Electrocardiogram then showed sinus tachycardia at a rate of 125 per minute, normal QRS duration and normal axis (Figure 3.3).
