Introduction: Refractory out-of-hospital cardiac arrest (r-OHCA) in patients with pulmonary embolism (PE) has poor outcome. Data about use of extracorporeal membrane oxygenation (ECMO) in PE are heterogenous and there is minimal evidence for its use in patients presenting with r-OHCA. Hypothesis: To describe in detail profile, initial settings of cardiac arrest (CA) and clinical course of patients with PE presenting with r-OHCA and its specifics in comparison to patients with r-OHCA of other cause. The special attention was paid to the use of ECMO and its potential benefit for patient prognosis. Methods: We reanalyzed subgroup of patients with PE from Prague OHCA study - a randomized control trial evaluating the effect of hyperinvasive approach including the use of ECMO in r-OHCA. Patients characteristics, the specifics of CA settings and the outcome were compared to the patients with other cause of r-OHCA. The neurologically favorable survival was then compared between PE patients randomized to Hyperinvasive and Standard arm of the study. Results: The PE was identified as a cause of CA in 24 (9.4 %) patients in Prague OHCA study. PE patients were more likely women (12 [50 %] vs 32 [13.8 %]) with non-shockable initial rhythm (23 [95.8 %] vs 77 [33.2 %]; P < 0.0001). The CA occurs more frequently after arrival of emergency medical service (14 [58.3 %], vs 22 [9.5 %]; P < 0.0001), had shorter time to hospital admission (median in minutes [IQR], 40 [34.5-57.8] vs 54 [46-64]; P = 0.01) with more severe acidosis at admission (median pH [IQR]; 6.83 [6.75-6.88] vs 6.98 [6.82-7.14] P = 0.0008). The primary outcome of patients with PE - CPC 1 or 2 at 180 days - was significantly worse (2 [8.3 %] vs 66 [28.4 %]; P = 0.049). There was non-significant difference in primary outcome - CPC 1 or 2 at 180 days - between PE patients in Hyperinvasive (12 [50%]) and Standard arm of the study (2 [16.7 %] vs 0; P = 0.24). Conclusion: The initial profile of patients and the settings of CA in patients with r-OHCA and PE differs from patients with other CA cause and their prognosis is significantly worse. The Hyperinvasive approach did not improved outcome in this subgroup of patients.

Introduction: The intra-aortic balloon pump (IABP) and Impella are left ventricular unloading devices with peripheral venoarterial extracorporeal membrane oxygenation (VA-ECMO) in place and later serve as bridging therapy when VA-ECMO is terminated. We aimed to determine the potential differences in clinical outcomes and rate of complications between the two combinations of mechanical circulatory support. Methods: This was a retrospective, single institutional cohort study conducted in the intensive care unit (ICU) of Queen Elizabeth Hospital, Hong Kong. Inclusion criteria included all patients aged ⩾18 years, who had VA-ECMO support, and who had left ventricular unloading by either IABP or Impella between January 1, 2018 and October 31, 2020. Patients <18 years old, with central VA-ECMO, who did not require left ventricular unloading, or who underwent surgical venting procedures were excluded. The primary outcome was ECMO duration. Secondary outcomes included length of stay (LOS) in the ICU, hospital LOS, mortality, and complication rate. Results: Fifty-two patients with ECMO + IABP and 14 patients with ECMO + Impella were recruited. No statistically significant difference was observed in terms of ECMO duration (2.5 vs 4.6 days, p = 0.147), ICU LOS (7.7 vs 10.8 days, p = 0.367), and hospital LOS (14.8 vs 16.5 days, p = 0.556) between the two groups. No statistically significant difference was observed in the ECMO, ICU, and hospital mortalities between the two groups. Specific complications related to the ECMO and Impella combination were also noted. Conclusions: Impella was not shown to offer a statistically significant clinical benefit compared with IABP in conjunction with ECMO. Clinicians should be aware of the specific complications of using Impella.

A 59-year-old man was diagnosed with a massive pulmonary embolism. Despite thrombolysis there were two episodes of cardiac arrest and following recovery of spontaneous circulation profound cardiorespiratory failure ensued. An extracorporeal membrane oxygenation retrieval team initiated veno-venous extracorporeal membrane oxygenation on site to facilitate transfer to the extracorporeal membrane oxygenation centre. An excellent outcome is reported in the short term. This represents one of the few published cases of veno-venous extracorporeal membrane oxygenation for a massive pulmonary embolism following thrombolysis.

Abstract Background: Veno-arterial extracorporeal membrane oxygenation (ECMO) is increasingly being utilized in patients with massive pulmonary embolism (PE). However, the efficacy and the safety remain uncertain. This study aimed to investigate clinical courses and outcomes in ECMO-treated patients with acute PE.Methods: Twenty-one patients with acute PE rescued by ECMO from January 2012 to December 2019 were retrospectively analysed. Clinical features, laboratory biomarkers, and imaging findings of these patients were reviewed, and the relationship with immediate outcome and clinical course was investigated.Results: Sixteen patients (76.2%) experienced refractory circulatory collapse requiring cardiopulmonary resuscitation (CPR) or ECMO support within 2 hours after the onset of cardiogenic shock, and none could receive definitive reperfusion therapy before ECMO initiation. Before or during ECMO support, more than 90% of patients had imaging signs of right ventricular (RV) dysfunction. In normotension patients, the computed tomography (CT) value was a valuable predictor of rapid disease progression compared with cardiac troponin I level. Ultimately, in-hospital death occurred in 10 patients (47.6%) and 90% of them died of prolonged CPR-related brain death. Cardiac arrest was a significant predictor of poor prognosis (p = 0.001). Conclusions: ECMO appears to be a safe and effective circulatory support in patients with massive PE. Close monitoring in intensive care unit is recommended in patients with RV dysfunction and aggressive use of ECMO may reduce the risk of sudden cardiac arrest and improve clinical outcome.

Introduction: With one person in Canada suffering an out-of-hospital cardiac arrest (OHCA) every 12 minutes and an estimated survival to hospital discharge with good neurologic function ranging from 3 to 16%, OHCA represents a major source of morbidity and mortality. An evolving adjunct for resuscitation of OHCA patients is the use of extracorporeal membrane oxygenation-assisted CPR (ECPR). The purpose of this systematic review is to investigate the survival to hospital discharge with good neurologic recovery in patients suffering from OHCA treated with ECPR compared to those who received standard advanced cardiac life support with conventional CPR (CCPR) alone. Methods: A systematic database search of both MEDLINE &amp; EMBASE was performed up until September 2016 to identify studies with ≥5 patients reporting ECPR use in adults (age ≥16 years) with OHCA. Only studies reporting survival to hospital discharge were included. All identified studies were assessed independently using pre-determined inclusion criteria by two reviewers. Study quality and risk of bias were evaluated using the Newcastle Ottawa regulations assessment scale. Results: Of the 1065 records identified, 54 studies met all inclusion criteria. Inter-rater reliability was high with a kappa statistic of 0.85. The majority of studies were comprised of case series (n=45) of ECPR with 5 to 83 patients/study. Out of the 45 case series, 37 presented neurologic data at hospital discharge and demonstrated a broad range of patients surviving with good neurologic outcome (0 to 71.4%). Only 9 cohort studies with relevant control group (CCPR) were identified (38 to 21750 patients/study). Preliminary analysis demonstrated that 6 cohort studies were sufficient quality to compare ECPR to CCPR. All 6 studies showed significantly increased survival to hospital discharge with good neurologic recovery (ECPR 10.6 to 41.6% vs CCPR 1.5 to 7.7%, respectively). Conclusion: Given the paucity of studies using appropriate comparators to evaluate the impact of ECMO, our confidence in a clinically relevant difference in outcomes compared to current standards of care for OHCA remains weak. Interestingly, a limited number of studies with suitable controls demonstrated a potential benefit associated with ECPR in the management of OHCA in selected patients. In this state of equipoise, high quality RCT data is urgently needed.
