Abstract Background Venoarterial extracorporeal membrane oxygenation (VA-ECMO) support is a lifesaving tool used in the treatment of cardiogenic shock, acute heart failure, or extracorporeal cardiopulmonary resuscitation (CPR). We report on a single center experience with ECMO and aim to identify the prognostic markers for in-hospital mortality and death at 72 hours after ECMO. Methods Between 2011 and 2019 we evaluated 131 patients, who received ECMO. Collected data was analyzed to identify baseline characteristic, outcomes including clinical variables predictive of poor outcome. Results The mean age was 62.5 years, 67.2% were male patients, with prior CPR in 61.8%. The annual number of VA-ECMO procedures steadily increased, whereas in-hospital mortality is decreasing. Within the total cohort, the indication for VA-ECMO was cardiac arrest in 19.1%, acute coronary syndrome in 41.2%, acute heart failure in 23.7%, and myocarditis in 10.7%. Overall in-hospital mortality was 58.8%. Multivariate logistic regression model revealed presence of malignancy, history of revascularization, duration of cardiac arrest, and low BMI as independent predictors for mortality in 72 hours after ECMO (table). On the other hand, predictors of in-hospital mortality were prior congestive heart failure, male, and history of malignancy. The C-statistic for discriminating mortality in 72 hours after ECMO with the duration of cardiac arrest was 0.67 (figure). Conclusions Although the use of ECMO as a last line in the treatment of critical patients measures constitutes an important improvement in their care; with 41.2% overall survival; patient selection and timing of ECMO initiation remains challenging. The importance of consideration for ECMO use earlier in course of illness rather than later. Funding Acknowledgement Type of funding source: None

Background: Endomyocardial biopsy (EMB) has an important role in determining the pathogenesis of new-onset acute heart failure (new-AHF) when noninvasive testing is impossible. However, data on safety and histopathologic outcomes in patients requiring veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is lacking. Methods: A retrospective, multicenter cohort of patients undergoing EMB while requiring VA-ECMO for new-AHF between 1990 and 2020 was compared with a cohort of nontransplant related biopsies not requiring VA-ECMO. Primary end point of the study was to determine the safety of EMB. Additionally, we describe the underlying pathogenesis causing new-AHF based on histopathologic examination of the samples obtained. Results: A total of 23 patients underwent EMB while requiring VA-ECMO (10.0%), 125 (54.3%) during an unplanned admission, and 82 (35.7%) in elective setting. Major complications occurred in 8.3% of all procedures with a significantly higher rate in patients requiring VA-ECMO (26.1% versus 8.0% versus 3.7%, P =0.003) predominately due to the occurrence of sustained ventricular tachycardia or need of resuscitation (13.0% versus 3.2% versus 1.2%, P =0.02). EMB led to a histopathologic diagnosis in 78.3% of the patients requiring VA-ECMO which consisted primarily of patients with myocarditis (73.9%). Conclusions: EMB in patients requiring VA-ECMO can be performed albeit with a substantial risk of major complications. The risk of the procedure was offset by a histopathologic diagnosis in 78.3% of the patients, which for the majority consisted of patients with myocarditis. The important therapeutic and prognostic implications of establishing an underlying pathogenesis causing new-AHF in this population warrant further refinement to improve procedural safety.

The survival after veno-arterial extracorporeal membrane oxygenation score and its lactate modification predict in-hospital mortality in patients based on pre-extracorporeal membrane oxygenation variables. Cardiac arrest history is a significant variable in these scores; however, patients with ongoing cardiac arrest during cannulation were excluded from these models. The goal of this study is to validate the survival after veno-arterial extracorporeal membrane oxygenation score with a lactate modification among patients with ongoing cardiac arrest. In our study, the survival after veno-arterial extracorporeal membrane oxygenation score predicted mortality in all patients, but did so with higher discrimination among ongoing cardiac arrest patients with a lactate modification.

Background: The suitability of model for end-stage liver disease excluding international normalized ratio (MELD-XI) score to predict the incidence of acute kidney injury (AKI) and in-hospital mortality in adult patients with postcardiotomy cardiogenic shock (PCS) requiring venoarterial extracorporeal membrane oxygenation (VA ECMO) remains uncertain. This study was performed to explore whether the MELD-XI score has the association with the incidence of AKI and in-hospital mortality in these patients. Methods: Adult patients with PCS requiring VA ECMO from January 2012 to December 2017 were enrolled and first classified into AKI group ( n = 151) versus no-AKI group ( n = 132), then classified into survival group ( n = 143) versus no-survival group ( n = 140). Multivariate logistic regressions were performed to identify factors independently associated with AKI and mortality. Baseline data were defined as the first measurement available. Results: Of 283 patients, the incidence of AKI was 53.36%. The in-hospital mortality rates were 63.58% and 33.33% in patients with and without AKI (p < 0.0001). Baseline MELD-XI score, baseline serum total bilirubin (T-Bil), baseline blood urea nitrogen (BUN), baseline left ventricular ejection fraction (LVEF), sequential organ failure assessment (SOFA) score, and lactate level at ECMO initiation were shown to be associated with the AKI. Vasoactive-inotropic score (VIS) and SOFA score at ECMO initiation as well as renal failure requiring renal replacement therapy (RRT) were shown to be associated with in-hospital mortality. Conclusions: The baseline MELD-XI score, baseline BUN, baseline T-Bil, baseline LVEF, SOFA score and lactate at the initiation of ECMO were associated with AKI. AKI, SOFA score, and VIS at the initiation of ECMO were associated with in-hospital mortality, whereas MELD-XI score was not found to be associated with in-hospital mortality. A specific MELD-XI score as a threshold, as well as its sensitivity and specificity, needs to be confirmed in further studies.

Abstract Background Systemic rheumatic diseases (SRDs) are a group of inflammatory disorders that can require intensive care unit (ICU) admission because of multiorgan involvement with end-organ failure(s). Critically ill SRD patients requiring extracorporeal membrane oxygenation (ECMO) were studied to gain insight into their characteristics and outcomes. Methods This French monocenter, retrospective study included all SRD patients requiring venovenous (VV)- or venoarterial (VA)-ECMO admitted to a 26-bed ECMO-dedicated ICU from January 2006 to February 2020. The primary endpoint was in-hospital mortality. Results Ninety patients (male/female ratio: 0.5; mean age at admission: 41.6 ± 15.2 years) admitted to the ICU received VA/VV-ECMO, respectively, for an SRD-related flare (n = 69, n = 38/31) or infection (n = 21, n = 10/11). SRD was diagnosed in-ICU for 31 (34.4%) patients. In-ICU and in-hospital mortality rates were 48.9 and 51.1%, respectively. Nine patients were bridged to cardiac (n = 5) or lung transplantation (n = 4), or left ventricular assist device (n = 2). The Cox multivariable model retained the following independent predictors of in-hospital mortality: in-ICU SRD diagnosis, day-0 Simplified Acute Physiology Score (SAPS) II score ≥ 70 and arterial lactate ≥ 7.5 mmol/L for VA-ECMO–treated patients; diagnosis other than vasculitis, day-0 SAPS II score ≥ 70, ventilator-associated pneumonia and arterial lactate ≥ 7.5 mmol/L for VV-ECMO–treated patients. Conclusions ECMO support is a relevant rescue technique for critically ill SRD patients, with 49% survival at hospital discharge. Vasculitis was independently associated with favorable outcomes of VV-ECMO–treated patients. Further studies are needed to specify the role of ECMO for SRD patients.

Veno-arterial extracorporeal membrane oxygenation (VA ECMO) is a technique used in patients with severe heart failure. The aim of this study was to evaluate its effects on left ventricular afterload and fluid accumulation in lungs with electrical impedance tomography (EIT). In eight swine, incremental increases of extracorporeal blood flow (EBF) were applied before and after the induction of ischemic heart failure. Hemodynamic parameters were continuously recorded and computational analysis of EIT was used to determine lung fluid accumulation. With an increase in EBF from 1 to 4 l/min in acute heart failure the associated increase of arterial pressure (raised by 44 %) was accompanied with significant decrease of electrical impedance of lung regions. Increasing EBF in healthy circulation did not cause lung impedance changes. Our findings indicate that in severe heart failure EIT may reflect fluid accumulation in lungs due to increasing EBF.

Background No studies have explored the association between newly diagnosed infections after admission and clinical outcomes in patients with acute heart failure. We aimed to explore the factors associated with newly diagnosed infection after admission for acute heart failure, and its association with in‐hospital and post‐discharge clinical outcomes. Methods and Results Among 4056 patients enrolled in the Kyoto Congestive Heart Failure registry, 2399 patients without any obvious infectious disease upon admission were analyzed. The major in‐hospital and post‐discharge outcome measures were all‐cause deaths. There were 215 patients (9.0%) with newly diagnosed infections during hospitalization, and 2184 patients (91.0%) without infection during hospitalization. The factors independently associated with a newly diagnosed infection were age ≥80 years, acute coronary syndrome, non‐ambulatory status, hyponatremia, anemia, intubation, and patients who were not on loop diuretics as outpatients. The newly diagnosed infection group was associated with a higher incidence of in‐hospital mortality (16.3% and 3.2%, P <0.001) and excess adjusted risk of in‐hospital mortality (odds ratio, 6.07 [95% CI, 3.61–10.19], P <0.001) compared with the non‐infection group. The newly diagnosed infection group was also associated with a higher 1‐year incidence of post‐discharge mortality (19.3% in the newly diagnosed infection group and 13.6% in the non‐infection group, P <0.001) and excess adjusted risk of post‐discharge mortality (hazard ratio, 1.49 [95% CI, 1.08–2.07], P =0.02) compared with the non‐infection group. Conclusions Elderly patients with multiple comorbidities were associated with the development of newly diagnosed infections after admission for acute heart failure. Newly diagnosed infections after admission were associated with higher in‐hospital and post‐discharge mortality in patients with acute heart failure.

Background: The outcome after weaning from postcardiotomy venoarterial extracorporeal membrane oxygenation (VA-ECMO) is poor. In this study, we investigated the prognostic impact of arterial lactate levels at the time of weaning from postcardiotomy VA. Methods: This analysis included 338 patients from the multicenter PC-ECMO registry with available data on arterial lactate levels at weaning from VA-ECMO. Results: Arterial lactate levels at weaning from VA-ECMO (adjusted OR 1.426, 95%CI 1.157–1.758) was an independent predictor of hospital mortality, and its best cutoff values was 1.6 mmol/L (<1.6 mmol/L, 26.2% vs. ≥ 1.6 mmol/L, 45.0%; adjusted OR 2.489, 95%CI 1.374–4.505). When 261 patients with arterial lactate at VA-ECMO weaning ≤2.0 mmol/L were analyzed, a cutoff of arterial lactate of 1.4 mmol/L for prediction of hospital mortality was identified (<1.4 mmol/L, 24.2% vs. ≥1.4 mmol/L, 38.5%, p = 0.014). Among 87 propensity score-matched pairs, hospital mortality was significantly higher in patients with arterial lactate ≥1.4 mmol/L (39.1% vs. 23.0%, p = 0.029) compared to those with lower arterial lactate. Conclusions: Increased arterial lactate levels at the time of weaning from postcardiotomy VA-ECMO increases significantly the risk of hospital mortality. Arterial lactate may be useful in guiding optimal timing of VA-ECMO weaning.

Background Factors associated with poor prognosis following receipt of extracorporeal membrane oxygenation (ECMO) in adults with cardiac arrest remain unclear. We aimed to identify predictors of mortality in adults with cardiac arrest receiving ECMO in a nationally representative sample. Methods and Results The US Healthcare Cost and Utilization Project's National Inpatient Sample was used to identify 782 adults hospitalized with cardiac arrest who received ECMO between 2006 and 2014. The primary outcome of interest was all‐cause in‐hospital mortality. Factors associated with mortality were analyzed using multivariable logistic regression. The overall in‐hospital mortality rate was 60.4% (n=472). Patients who died were older and more often men, of non‐White race, and with lower household income than those surviving to discharge. In the risk‐adjusted analysis, independent predictors of mortality included older age, male sex, lower annual income, absence of ventricular arrhythmia, absence of percutaneous coronary intervention, and presence of therapeutic hypothermia. Conclusions Demographic and therapeutic factors are independently associated with mortality in patients with cardiac arrest receiving ECMO. Identification of which patients with cardiac arrest may receive the utmost benefit from ECMO may aid with decision‐making regarding its implementation. Larger‐scale studies are warranted to assess the appropriate candidates for ECMO in cardiac arrest.
