Abstract Background and objectives The optimal pulmonary revascularization strategy in acute massive pulmonary embolism (PE) requiring the implantation extra corporeal membrane oxygenation remains controversial, and data are sparse. Methods We conducted a systematic review and meta-analysis of available evidence regarding the use of mechanical reperfusion (i.e. surgical or catheter-based embolectomy) and fibrinolytic strategies (i.e. systemic fibrinolysis, catheter-directed fibrinolysis, or as stand-alone therapy) in terms of mortality and bleeding outcomes. Results The literature search identified 835 studies, 17 of which were included or a total of 321 PE patients with ECMO. In total, 31.1% were treated with mechanical pulmonary reperfusion, while 78.9% received fibrinolytic strategies. The mortality rate was 23.0% in the mechanical reperfusion group and 43.1% in the fibrinolysis group (Figure). The pooled OR for mortality with mechanical reperfusion was 0.46 (95% CI, 0.213–0.997; I2=28.3%) versus fibrinolysis. The rate of bleeding in PE patients under ECMO was 29.1% in the mechanical reperfusion group and 26.0% in the fibrinolytic reperfusion (OR, 1.09; 95% CI, 0.46–2.54; I2=0.0%) among 10 eligible studies with available bleeding data. The meta-regression model did not identify any relationship between the covariates “more than one pulmonary reperfusion therapy” and “ECMO implantation before pulmonary reperfusion therapy”, and outcomes. Conclusions The results of the present meta-analysis and meta-regression suggest that surgical embolectomy yields the best results, regardless of the timing of VA-ECMO implantation in the reperfusion timeline, and regardless of whether fibrinolysis has been administered or not.

During veno-arterial extracorporeal membrane oxygenation (VA-ECMO), the increase of left ventricular (LV) afterload can potentially increase the LV stress, exacerbate myocardial ischemia and delay recovery from cardiogenic shock (CS). Several strategies of LV unloading have been proposed. Systematic review and meta-analysis in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement included adult patients from studies published between January 2000 and March 2019. The search was conducted through numerous databases. Overall, from 62 papers, 7581 patients were included, among whom 3337 (44.0%) received LV unloading concomitant to VA-ECMO. Overall, in-hospital mortality was 58.9% (4466/7581). A concomitant strategy of LV unloading as compared to ECMO alone was associated with 12% lower mortality risk (RR 0.88; 95% CI 0.82–0.93; p < 0.0001; I2 = 40%) and 35% higher probability of weaning from ECMO (RR 1.35; 95% CI 1.21–1.51; p < 0.00001; I2 = 38%). In an analysis stratified by setting, the highest mortality risk benefit was observed in case of acute myocardial infarction: RR 0.75; 95%CI 0.68–0.83; p < 0.0001; I2 = 0%. There were no apparent differences between two techniques in terms of complications. In heterogeneous populations of critically ill adults in CS and supported with VA-ECMO, the adjunct of LV unloading is associated with lower early mortality and higher rate of weaning.

Objective: Intra-aortic balloon pump (IABP) is currently recommended as a strategy to address the increased afterload in patients who received venoarterial extracorporeal membrane oxygenation (VA-ECMO). The benefit of VA-ECMO with IABP in postcardiotomy cardiogenic shock is inconclusive. A systematic review and meta-analysis was conducted to assess the influence of VA-ECMO with IABP for postcardiotomy cardiogenic shock (PCS). Methods: The Cochrane Library, PubMed, and Embase were searched for all articles published from 1 January, 1964 to July 11, 2020. Retrospective cohort studies targeting the comparison of VA-ECMO with IABP and isolated VA-ECMO were included in this study. Results: We included 2251 patients in the present study (917 patients in the VA-ECMO with IABP group and 1334 patients in the isolated VA-ECMO group). Deaths occurred in 589 of 917 patients (64.2%) in the VA-ECMO with IABP group and occurred in 885 of 1334 patients (66.3%) in isolated VA-ECMO group. Pooling the results of all studies showed that VA-ECMO with IABP was not related to a reduced in-hospital mortality in patients who received VA-ECMO for PCS (RR, 0.95; 95% CI, 0.86–1.04; p = 0.231). In addition, VA-ECMO with IABP was not related to an increased rate of VA-ECMO weaning in patients who received VA-ECMO for PCS (RR, 1.28; 95% CI, 0.99–1.66; p = 0.058). Conclusions: This study indicates that VA-ECMO with IABP did not improve either in-hospital survival or weaning for VA-ECMO in postcardiotomy cardiogenic shock patients.

Abstract Background: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) has been widely used for patients with refractory cardiogenic shock (CS). A common side-effect of this technic is the resultant increase in left ventricular (LV) afterload which could potentially aggravate myocardial ischemia, delay ventricular recovery, and increase the risk of pulmonary congestion. Several LV unloading strategies have been proposed and implemented to mitigate these complications. However, it is still indistinct that which one is the best choice for clinical application. The objective of this Bayesian network meta-analysis (NMA) is to summarize the evidence and compare the efficacy of different LV unloading strategies during VA-ECMO.Methods: We will perform a systematic search to identify random controlled trials and cohort studies comparing different LV unloading strategies during VA-ECMO. PubMed, Embase, the Cochrane Library, and the International Clinical Trials Registry Platform (ICTRP) will be explored from their inception to 31 December 2020. The primary outcome will be in-hospital mortality. The secondary outcomes will include neurological complications, hemolysis, bleeding, limb ischemia, renal failure, gastrointestinal complications, sepsis, duration of mechanical ventilation, length of intensive care unit, and hospital stays. Pairwise and network meta-analysis will respectively be conducted using Stata (V.16, StataCorp) and Aggregate Data Drug Information System (ADDIS V.1.16.5), and the cumulative probability will be used to rank the included LV unloading strategies. The risk of bias will be conducted using the Cochrane Collaboration’s tool or Newcastle-Ottawa Quality Assessment Scale (NOS) according to their study design. Subgroup analysis, sensitivity analysis, and publication bias assessment will be performed. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) will be conducted to explore the quality of evidence.Discussion: This Bayesian network meta-analysis (NMA) will address the problem that which strategy could achieve left ventricular (LV) unloading most effectively during venoarterial extracorporeal membrane oxygenation and increase cardiogenic shock patient survival benefit, and will provide evidence for clinical decision-making.Systematic review registration: PROSPERO registry number: CRD42020165093.

The purpose of the systematic review and meta-analysis was to determine if low-ratio n-6/n-3 long-chain polyunsaturated fatty acid (PUFA) supplementation affects serum inflammation markers based on current studies.
