The primary outcome was the combination of recurrent PE, heart failure hospitalization, and all-cause death at 30 days. The analysis included 15 patients: mean age was 63.1 years and 14 (93%) were men. Overall, four (27%) patients presented with cardiac arrest, eight (53%) with ongoing obstructive shock, and three (20%) with persistent arterial hypotension. Veno-arterial extracorporal membrane oxygenation was implanted prior to aspiration embolectomy in eight (53%) patients. Three of seven patients without initial VA-ECMO support experienced periprocedural cardiac arrest, of whom two received ECMO support before completion of embolectomy. Veno-arterial extracorporal membrane oxygenation weaning was successful in all patients after a mean of 5.4 days. There was one periprocedural death in a patient who did not receive VA-ECMO support following a periprocedural cardiac arrest. The primary outcome at 30 days occurred in five (33.3%; 95% confidence interval 13.0\u201361.3%) patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study
