A 63-year-old man with renal cell carcinoma and hemorrhagic brain metastases presenting with submassive PE, felt not safe for anticoagulation. The patient was normotensive but had decreased RV motility on Echocardiogram, pro-BNP of 930 pg/mL, and troponin I elevation of 0.46 ng/mL, and ECG changes. a ECG in a patient with submassive PE depicts ischemia demonstrates inverted T waves in V1–V4 leads, a representative ECG abnormality that may be seen with submassive PE. b CTA demonstrates right main pulmonary artery and lobar pulmonary emboli (white arrows). c CTA demonstrates increased RV/LV ratio with blue calipers measuring the RV and red calipers measuring the left ventricle. d Before and after mechanical thrombectomy pulmonary angiogram images depicting improved patency of the right main pulmonary artery (solid arrow) and perfusion to the right lower lobe (open arrow) compared to before
