A 43-year-old male patient, with a history of chronic thromboembolic pulmonary hypertension with progressive dyspnea and worsening functional status presented for definitive surgical treatment. He underwent thromboendarterectomy which was complicated by acute right ventricular dysfunction requiring venoarterial extracorporeal membrane oxygenation (VA ECMO). Post-operative attempts to wean the patient from VA ECMO were unsuccessful, and echocardiography revealed worsening right heart failure. A pulmonary CT angiography (CTA) was requested to assess for recurrent pulmonary artery thrombosis on post-operative day 11.
