Emergent mechanical thrombectomy for right atrial clot and massive pulmonary embolism using flowtriever

FIGURE 1. a. b. Axial (1a) and coronal (1b) CT images show saddle pulmonary embolus extending from the main pulmonary artery (PA) into both the right and left main pulmonary artery

FIGURE 2. a. b. Axial CT sections showing the 4 chamber view of heart showing the right atrial clot in transit ( White arrows) and the abnormal high RV/LV diameter ratio > 1 suggesting right heart strain

FIGURE 3. a. b. IVC gram at different levels shows the filling defect at the cavo‐atrial junction (White arrow) and extending into the right atrium consistent with the CT findings

FIGURE 4. Aspirated clot through the FlowTriever

FIGURE 5. a. b. and c. Pulmonary angiography showing the findings of filling defect in the main (a), right (b) and left (c) pulmonary arteries (Black arrows)

FIGURE 6. Follow‐up CT scan shows no residual clot in PA and reduced RV/LV diameter ratio
