RESUMEN
Surgical pulmonary embolectomy is a procedure that is often used to rescue patients with massive pulmonary embolism (PE) and circulatory collapse that have failed or may not be ideal candidates for other systemic and endovascular treatment modalities. This procedure typically involves a sternotomy and the use of cardiopulmonary bypass (CPB), which requires full systemic anticoagulation. Here, we report the case of a surgical pulmonary embolectomy performed on venoarterial extracorporeal membrane oxygenation (VA-ECMO) rather than CPB to minimize systemic anticoagulation. The patient had suffered a cardiac arrest due to a saddle PE and required VA-ECMO which was complicated by a concomitant intracranial hemorrhage. The patient tolerated the surgical pulmonary embolectomy performed on VA-ECMO without procedure-related complications, and the ECMO support did not substantially complicate the technical performance of the procedure. In contrast to surgical pulmonary embolectomy performed on CPB, greater attention must be paid to volume status when performing the procedure on VA-ECMO since there is no blood reservoir. This case suggests cardiopulmonary support on ECMO as a viable strategy for surgical embolectomy in patients with unstable PEs in whom thrombolysis or full systemic anticoagulation are contraindicated.
RESUMEN
Severe acute respiratory syndrome coronavirus 2 is associated with a prothrombotic state in infected patients. After presenting a case of right ventricular thrombus in a patient with coronavirus disease-2019 (COVID-19), we discuss the unique challenges in the evaluation and treatment of COVID-19 patients, highlighting our COVID-19-modified pulmonary embolism response team algorithm.

RESUMEN
We discuss a patient who presented with cardiogenic shock secondary to massive pulmonary embolism and right ventricular failure. She was managed by a multidisciplinary heart team and treated with catheter-directed thrombectomy, followed by ProtekDuo (Tandem [Liva Nova], London, United Kingdom) heart percutaneous right ventricular support leading to complete recovery from this often fatal condition.
