“PERT-inent” Management: The Role of the Pulmonary Embolus Response Team in Managing Paradoxical Embolus in Transit

ABSTRACT: A 52-year-old man presented with palpitations and dyspnea. Extensive bilateral pulmonary emboli (PEs) were identified on computed tomography pulmonary angiogram. Transthoracic echocardiography demonstrated a mobile bi-atrial thrombus straddling the interatrial septum. Consensus decision of a multidisciplinary pulmonary embolus response team was made for emergency thrombectomy of the pulmonary and intra-cardiac clot. Intraoperatively, a patent foramen ovale was identified and repaired. He had an excellent outcome and was discharged home on oral anticoagulation. In this unique case of a bi-atrial thrombus and sub-massive PEs, we demonstrate the utility of dedicated pulmonary embolus response teams in providing rapid and individualized management decisions for complex PE patients.

Project description:BackgroundOver the last few years, the concept of multidisciplinary pulmonary embolism response teams (PERTs) has emerged to encounter the increasing variety and complexity in managing acute pulmonary embolism (PE).PurposeTo investigate PERT's composition and added clinical value in a university center in Germany.MethodsOver 4 years (01/2019-11/2022), patients with confirmed PE were enrolled in a prospective single-center cohort study (PERT Mainz). We investigated the composition of PERT and compared, after propensity score matching, patients with acute PE before and after the initiation of PERT at our Medical University Centre. The primary outcome was in-hospital PE-related mortality.ResultsFrom 2019 to 2022, 88 patients with acute PE with a PERT decision were registered. Of those, 13 (14.8%) patients died during the in-hospital stay. Patients evaluated by a PERT had a median age of 68; 48.9% were females, and 21.7% suffered from malignancy. Right ventricular dysfunction was present in 76.1% of all patients. In total, 42.0% were classified as intermediate-high-risk PE and 11.4% as high-risk PE. First PERT contact mainly originated from emergency departments (33.3%) and intensive care units (30.0%), followed by chest pain units (21.3%) and regular wards (12.0%). The participation rate of medical specialties demonstrated that cardiologists (100%) or cardiac/vascular surgeons (98.6%) were included in almost all PERT consultations, followed by radiologists (95.9%) and anesthesiologists (87.8%). Compared to the PERT era, more patients in the pre-PERT era were classified as simplified pulmonary embolism severity index (sPESI) ≥ 1 (78.4% vs 71.6%) and as high-risk PE according to ESC 2019 guidelines (18.2% vs. 11.4%). In the pre-PERT era, low- and intermediate-low patients with PE received more frequently advanced reperfusion therapies such as systemic thrombolysis or surgical embolectomy compared to the PERT era (10.7% vs. 2.5%). Patients in the pre-PERT were found to have a considerably higher all-cause mortality and PE-related mortality rate (31.8% vs. 14.8%) compared to patients in the PERT era (22.7% vs. 13.6%). After propensity matching (1:1) by including parameters as age, sex, sPESI, and ESC risk classes, univariate regression analyses demonstrated that the PE management based on a PERT decision was associated with lower risk of all-cause mortality (OR, 0.37 [95%CI 0.18-0.77]; p = 0.009). For PE-related mortality, a tendency for reduction was observed (OR, 0.54 [95%CI 0.24-1.18]; p = 0.121).ConclusionPERT implementation was associated with a lower risk of all-cause mortality rate in patients with acute PE. Large prospective studies are needed further to explore the impact of PERTs on clinical outcomes.
