Patients
A total of 154 consecutive patients with MPE, initially diagnosed by either computed tomography or echocardiography from April 2016 to June 2020 transferred from emergency department to our catheterization laboratory, were retrospectively evaluated, of whom 29 patients met the criteria for high-risk PE complicated by profound cardiogenic shock or that required CPR (n=29), were enrolled in the study to analyze clinical outcomes. Written informed consent was obtained from each enrolled patient or from the family after the purpose and the risk of the treatment were fully explained. The Institutional Committee of Ethics in Research approved this clinical research project.
