Kidney Increase Natriuresis but Not Glomerular Filtration Under Veno-venous ECMO, a Retrospective Study.

PURPOSE: Acute kidney injury is a frequent complication of acute respiratory distress syndrome (ARDS). We aim to study the evolution of kidney function in patients presenting severe ARDS and requiring veno-venous extracorporeal membrane oxygenation (VV ECMO). METHODS: We conducted a multicenter retrospective study, including adult patients requiring VV ECMO for ARDS. The primary outcome was the evolution of the serum creatinine level after VV ECMO initiation. Secondary outcomes were change in urine output, and urine biochemical parameters after VV ECMO initiation. RESULTS: One hundred and two patients were included. VV ECMO was initiated after a median of 6 days of mechanical ventilation, mainly for ARDS caused by COVID-19 (73%). Serum creatinine level did not significantly differ after VV ECMO initiation (P = .20). VV ECMO was associated with a significant increase in daily urine output (+6.6 mL/kg/day, [3.8;9.3] P < .001), even after adjustment for potential confounding factors; with an increase in natriuresis. The increase in urine output under VV ECMO was associated with a reduced risk of receiving kidney replacement therapy (OR 0.4 [0.2;0.8], P = .026). CONCLUSIONS: VV ECMO initiation in severe ARDS is associated with an increase in daily urine output and natriuresis, without change in glomerular filtration rate.

[Mechanical management of refractory form of heart failure]. / Prise en charge mécanique de l'insuffisance cardiaque avancée.

Although the initial management of heart failure is essentially pharmacological, the use of mechanical circulatory support may become necessary in advanced forms. In cardiogenic shock, temporary mechanical circulatory support should be considered, while in more stable forms of advanced heart failure, implantation of a long-term left ventricular assist device (LVAD) can prolong survival and improve patient's quality of life. Recent improvements in LVAD technology have reduced post-implant complications, but the procedure is not without risk and requires close clinical follow-up.

Bien que la prise en charge initiale de l'insuffisance cardiaque soit essentiellement pharmacologique, le recours à des assistances circulatoires mécaniques peut devenir nécessaire dans les formes dites avancées. Dans le choc cardiogénique, l'utilisation d'assistances circulatoires mécaniques temporaires est à considérer alors que pour les formes d'insuffisance cardiaque avancée mieux stabilisées, l'implantation d'une assistance ventriculaire gauche de longue durée (Left Ventricular Assist Device - LVAD) permet de prolonger la survie et d'améliorer la qualité de vie des patients. Les améliorations technologiques récentes des LVAD ont permis de diminuer les complications, mais cette intervention n'est pas sans risque et nécessite un suivi clinique rapproché.

Oesophageal balloon positioning by echocardiography to guide positive pressure ventilation.

Understanding the respiratory mechanics of ARDS patients is crucial to avoid ventilator-induced lung injury (VILI), and this is much more challenging if not only lung compliance is altered but the whole compliance of the respiratory system is abnormal, as in obese patients. We face this problem daily in the ICU, and to optimize ventilation, we estimate respiratory mechanics using an oesophageal balloon. The balloon position is crucial to assess reliable values. In the present technical note, we describe the use of echocardiography to confirm the correct position of this instrument.

[Cardiac surgery in the time of COVID19 - A narrative of three very unusual cases and lessons learned]. / Chirurgie cardiaque au temps du Covid-19 - Récit de trois cas très inhabituels et leçons retenues.

COVID19 altered and impacted medical and surgical practice around the world. Standard of care and routine procedures are disrupted. Majors shift in personnel, and ad hoc new team as well as delocalization and working with new infrastructures are further challenges to be dealt with. This review of three very unusual scenarios illustrates pitfalls and dangers harbored in the re-shaped landscape of COVID19 exemplifying the narrow path bridging from the medical and surgical comfort zone to uncharted territory and eventually leading to collateral damage.

Le Covid-19 a profondément modifié et sévèrement impacté les pratiques médicales et chirurgicales à long terme. Les standards de prise en charge et les procédures de routine sont altérés, voire perturbés. Des mutations majeures au niveau du personnel et des équipes de même que la délocalisation ou le travail avec de nouvelles infrastructures sont autant de défis à relever, encore aujourd'hui. Trois scénarios inhabituels illustrent les pièges et les dangers qui se cachent dans le paysage marqué par le Covid-19. Ces exemples démontrent la marge étroite entre la zone de confort médicale et chirurgicale classique et l'appréhension d'une situation inhabituelle qui risque d'entraîner des dommages collatéraux pour les patients.

Thiamine, Ascorbic Acid, and Hydrocortisone As a Metabolic Resuscitation Cocktail in Sepsis: A Meta-Analysis of Randomized Controlled Trials With Trial Sequential Analysis.

OBJECTIVES: Sepsis is a common condition in the ICU. Despite much research, its prognosis remains poor. In 2017, a retrospective before/after study reported promising results using a combination of thiamine, ascorbic acid, and hydrocortisone called "metabolic resuscitation cocktail" and several randomized controlled trials assessing its effectiveness were performed. DESIGN: We conducted a systematic review and meta-analysis of randomized controlled trials in septic ICU patients to assess the effects of this combination therapy. SETTING: PubMed, Embase, and the Cochrane library databases were searched from inception to March of 2021. Data were extracted independently by two authors. The main outcome was the change in Sequential Organ Failure Assessment score within 72 hours. Secondary outcomes included renal composite endpoints (acute kidney injury) Kidney Disease - Improving Global Outcome organization stage 3 or need for renal replacement therapy, vasopressor duration, and 28-day mortality. SUBJECTS: We included randomized controlled trials with patients admitted to the ICU with sepsis or septic shock. INTERVENTION: The trials compared a combination of thiamine, ascorbic acid, and hydrocortisone to standard care or placebo in patients admitted to ICU with sepsis or septic shock. MEASUREMENTS AND MAIN RESULTS: We included eight randomized controlled trials (n = 1,335 patients). Within 72 hours, the median of mean improvement was -1.8 and -3.2 in the control and intervention groups, respectively (eight randomized controlled trials, n = 1,253 patients); weighted mean difference -0.82 (95% CI, -1.15 to -0.48). Data were homogeneous and the funnel plot did not suggest any publication bias. Duration of vasopressor requirement was significantly reduced in the intervention group (six randomized controlled trials). There was no evidence of a difference regarding the ICU mortality and the renal composite outcome (acute kidney injury KDIGO 3 or need for renal replacement therapy, seven randomized controlled trials). CONCLUSIONS: Metabolic resuscitation cocktail administrated in ICU septic patients improves change in Sequential Organ Failure Assessment score within 72 hours. However, this improvement is modest and its clinical relevance is questionable. The impact on renal failure and mortality remains unclear.

Very low blood flow carbon dioxide removal system is not effective in a chronic obstructive pulmonary disease exacerbation setting.

Extracorporeal carbon dioxide removal (ECCO2 R) is a low blood flow veno-venous extracorporeal membrane oxygenation technique that provides artificial blood CO2 removal. Recently, a new ECCO2 R system (PrismaLung), providing very low blood flow has been commercialized. The aim of this study is to report its use in severe chronic obstructive pulmonary disease (COPD) patients needing an ECCO2 R therapy. Six severe COPD patients with acute exacerbation leading to refractory hypercapnic respiratory acidosis were treated with ECCO2 R therapy. Two different systems were used: a PrismaLung system and a conventional ECCO2 R device. The maximum blood flow provided by PrismaLung was significantly lower than that with the conventional ECCO2 R system. In three patients initially treated with PrismaLung, there were no improvements in pH, PaCO2 , or RR. Thus, the therapy was switched to a conventional ECCO2 R system in these three patients, and three others were treated from the outset by the conventional ECCO2 R system, providing significant improvement in pH, PaCO2 , and RR. The present retrospective study describes the first use of PrismaLung in severe COPD patients with acute exacerbation. When compared with a higher blood flow ECCO2 R system, our results show that this novel, very low-flow device is not able to remove sufficient CO2 , normalize pH or decrease respiratory rate.

The use of extracorporeal carbon dioxide removal in acute chronic obstructive pulmonary disease exacerbation: a narrative review.

Chronic obstructive pulmonary disease (COPD) exacerbation induces hypercapnic respiratory acidosis. Extracorporeal carbon dioxide removal (ECCO2R) aims to eliminate blood carbon dioxide (CO2) in order to reduce adverse effects from hypercapnia and the related acidosis. Hypercapnia has deleterious extra-pulmonary consequences in increasing intracranial pressure and inducing and/or worsening right heart failure. During COPD exacerbation, the use of ECCO2R may improve the efficacy of non-invasive ventilation (NIV) in terms of CO2 removal, decrease respiratory rate and reduce dynamic hyperinflation and intrinsic positive end expiratory pressure, which all contribute to increasing dead space. Moreover, ECCO2R may prevent NIV failure while facilitating the weaning of intubated patients from mechanical ventilation. In this review of the literature, the authors will present the current knowledge on the pathophysiology related to COPD, the principles of the ECCO2R technique and its role in acute and severe decompensation of COPD. However, despite technical advances, there are only case series in the literature and few prospective studies to clearly establish the role of ECCO2R in acute and severe COPD decompensation.

An unusual thrombus location in a Heartmate 3TM device with fatal outcome.

Even if the HeartMate 3TM left ventricular assist device is associated with excellent outcomes, complications, such as pump thrombosis continue to affect patients on hemodynamic support. We report the history of a 68-year-old man who underwent implantation of an HeartMate 3TM as a bridge to transplantation. Nineteen months later, he developed signs of heart failure leading to cardiogenic shock. Neither clinical examination nor parameters from the device allowed a clear-cut diagnosis. Only surgical exploration revealed the presence of clots between the polyethylene terephthalate (Dacron®) and polytetrafluoroethylene tubes. This constitutes a weakness of this device for which we propose to the manufacturer for minimal modifications to overcome the problem.

In situ liver splitting under extracorporeal membrane oxygenation in brain-dead donor.

Hemodynamic instability is generally considered as a contraindication to liver splitting, in particular when using an in situ technique. We describe the cases of two young donors with brain death in whom refractory cardiac arrest and hemodynamic instability were supported by veno-arterial extracorporeal membrane oxygenation (VA-ECMO), allowing uneventful in situ splitting. Two adult and two pediatric liver recipients were successfully transplanted with immediate graft function. Favorable outcomes were also observed for the other transplanted organs, including one heart, two lungs, and four kidneys. Refractory cardiac arrest and hemodynamic instability corrected by VA-ECMO should not be considered as a contraindication to in situ liver splitting.

Respiratory changes in subclavian vein diameters predicts fluid responsiveness in intensive care patients: a pilot study.

The present pilot study investigated whether respiratory variation in subclavian vein (SCV) diameters correlates with fluid responsiveness in mechanically ventilated patients. Monocentric, prospective clinical study on fluid responsiveness in adult sedated, mechanically ventilated ICU patient, monitored with the PiCCO™ system (Pulsion Medical System, Germany), and requiring a fluid challenge (FC). A 10-min fluid bolus of 500 mL of 0.9% saline was administered. Cardiac output (CO) and dynamic parameters [stroke volume variation (SVV) and pulse pressure variation (PPV)] measured by transpulmonary thermodilution and pulse contour analysis (PiCCO™) as well as classical hemodynamic parameters were recorded at baseline and after FC. Fluid responsiveness was described as an increase in CO of ≥ 15%. Ultrasound measurements obtained in the subclavian long-axis view were used to calculate the SCVvariability index. A cut-off value for SCV variation for the prediction of fluid responsiveness was determined using receiver operating curve (ROC) analysis. Nine of 20 FCs (45%) induced an increase in CO of ≥ 15%. At baseline, the SCVvariability index was greater in responders than in non-responders (34.0 ± 21.4 vs. 9.0 ± 5.5; p = 0.0005). Diagnostic performance for the SCVvariability index revealed a cut-off value of 14 with a sensitivity of 100% [Confidence interval (CI) 95% (90; 100)] and a specificity of 82% [CI 95% (48; 98)] for the prediction of fluid responsiveness. Other parameters, such as SVV and PPV, could not predict fluid responsiveness. The correlation coefficient between CO variation and the SCVvariability index was 0.73 (p < 0.001). The SCVvariability index was a reliable, non-invasive parameter for the prediction of fluid responsiveness at the bedside of mechanically ventilated, critically ill patients in this pilot study.

Reproducibility of transpulmonary thermodilution cardiac output measurements in clinical practice: a systematic review.

Measuring cardiac output (CO) is an integral part of the diagnostic and therapeutic strategy in critically ill patients. During the last decade, the single transpulmonary thermodilution (TPTD) technique was implemented in clinical practice. The purpose of this paper was to systematically review and critically assess the existing data concerning the reproducibility of CO measured using TPTD (COTPTD). A total of 16 studies were identified to potentially be included in our study because these studies had the required information that allowed for calculating the reproducibility of COTPTD measurements. 14 adult studies and 2 pediatric studies were analyzed. In total, 3432 averaged CO values in the adult population and 78 averaged CO values in the pediatric population were analyzed. The overall reproducibility of COTPTD measurements was 6.1 ± 2.0 % in the adult studies and 3.9 ± 2.9 % in the pediatric studies. An average of 3 boluses was necessary for obtaining a mean CO value. Achieving more than 3 boluses did not improve reproducibility; however, achieving less than 3 boluses significantly affects the reproducibility of this technique. The present results emphasize that TPTD is a highly reproducible technique for monitoring CO in critically ill patients, especially in the pediatric population. Our findings suggest that obtaining a mean of 3 measurements for determining CO values is recommended.

Thoracic epidural analgesia: a new approach for the treatment of acute pancreatitis?

This review article analyzes, through a nonsystematic approach, the pathophysiology of acute pancreatitis (AP) with a focus on the effects of thoracic epidural analgesia (TEA) on the disease. The benefit-risk balance is also discussed. AP has an overall mortality of 1 %, increasing to 30 % in its severe form. The systemic inflammation induces a strong activation of the sympathetic system, with a decrease in the blood flow supply to the gastrointestinal system that can lead to the development of pancreatic necrosis. The current treatment for severe AP is symptomatic and tries to correct the systemic inflammatory response syndrome or the multiorgan dysfunction. Besides the removal of gallstones in biliary pancreatitis, no satisfactory causal treatment exists. TEA is widely used, mainly for its analgesic effect. TEA also induces a targeted sympathectomy in the anesthetized region, which results in splanchnic vasodilatation and an improvement in local microcirculation. Increasing evidence shows benefits of TEA in animal AP: improved splanchnic and pancreatic perfusion, improved pancreatic microcirculation, reduced liver damage, and significantly reduced mortality. Until now, only few clinical studies have been performed on the use of TEA during AP with few available data regarding the effect of TEA on the splanchnic perfusion. Increasing evidence suggests that TEA is a safe procedure and could appear as a new treatment approach for human AP, based on the significant benefits observed in animal studies and safety of use for human. Further clinical studies are required to confirm the clinical benefits observed in animal studies.

Effects of acute hemorrhage on intrapulmonary shunt in a pig model of acute respiratory distress-like syndrome.

BACKGROUND: In acute respiratory distress syndrome (ARDS), gas exchange and respiratory system mechanics (compliance) are severely impaired. Besides ventilatory parameters, the degree of respiratory abnormality can be influenced by the circulatory state. This study investigated the influence of acute hypovolemia on the respiratory system. METHODS: We performed a secondary analysis of a previous study including 8 pigs with ARDS-like syndrome induced by lung lavage and surfactant depletion method (ARDS group) and 10 mechanically ventilated pigs with no intervention (CTRL group). Animals of both groups were subjected to hemorrhage and retransfusion successively. We reanalyzed the effect of acute blood volume variations on intrapulmonary shunt (shunt), arterial oxygenation (PaO2:FiO2), global oxygen delivery (DO2) and respiratory system compliance (Crs). RESULTS: In the ARDS group, after hemorrhage, shunt decreased (-28 +/- 3.5 % (p < 0.001)), respiratory system compliance (Crs) increased (+5.1 +/- 1.0 ml/cm H2O (p < 0.001)) moreover, there was a concurrent increase in PaO2:FiO2 (+113 +/- 19.1 mmHg; p < 0.001) but this did not prevent a reduction in DO2 (-317 +/- 49.8 ml/min; p < 0.001). Following retransfusion, shunt and Crs return towards pre-hemorrhage values. Similar changes, but of smaller magnitude were observed in the CTRL group, except that no significant changes in oxygenation occurred. CONCLUSIONS: The present analysis suggests that an acute decrease in blood volume results in a decrease in shunt with a parallel improvement in arterial oxygenation and an increase in Crs during ARDS-like syndrome. Our results strengthen the importance to integrate the circulatory condition in the analysis of the state of the respiratory system. However, the translation of this physiological model in a clinical perspective is not straightforward because our model of acute and severe hemorrhage is not strictly equivalent to a progressive hypovolemia, as could be obtained in ICU by diuretic. Furthermore, the present model does not consider the impact of blood loss induced decrease of DO2 on other vital organs function. TRIAL REGISTRATION: 'Not applicable'.

Massive pulmonary embolism leading to cardiac arrest: one pathology, two different ECMO modes to assist patients.

Massive acute pulmonary embolism (MAPE) represents a significant risk for morbidity and mortality. The potential for sudden and fatal deterioration highlights the need for a prompt diagnosis and appropriate intervention. Using two cases reports, we describe two different modes of successful ECMO implantation (VA-ECMO vs. VV-ECMO) for MAPE leading to cardiac arrest. A 27-year-old patient with a severe trauma presented with a MAPE leading to cardiac arrest. In this case, which had absolute contraindications of thrombolysis, a VA-ECMO was successfully implanted. Additionally, a 56-year-old patient presented with a MAPE leading to cardiac arrest. Although intravenous thrombolysis allowed for hemodynamic stabilization, the patient remained severely hypoxemic with RV dilation. A VV-ECMO was successfully implemented, leading to a rapid improvement in both oxygenation and RV function. ECMO can provide lifesaving hemodynamic and respiratory support in critically ill patients with a MAPE who are too unstable to tolerate other interventions or have failed other therapies. An important determinant of success in the use of ECMO for MAPE is the return of adequate RV function, which allows physicians to appropriately identify which type of ECMO to implant.

The LUCAS 2 chest compression device is not always efficient: an echographic confirmation.

Survival after cardiac arrest depends on prompt and effective cardiopulmonary resuscitation (CPR). Resuscitative teams are more frequently using mechanical chest compression devices, as documented in physiologic and experimental data, suggesting that these devices are more effective than manual CPR. A 41-year-old male patient presented with an ST-elevation myocardial infarction with cardiac arrest. The patient was immediately resuscitated by manual chest compressions; CPR was continued with a mechanical chest compression device (LUCAS 2). The patient had experienced a 15-minute period of "low-flow" without "no-flow" episode. After a discussion with the heart team, we decided that the patient was a candidate for extracorporeal membrane oxygenation (ECMO) therapy. During the ECMO implantation, we noticed that while performing transesophageal echocardiography, chest compressions were ineffective with the machine. After the ECMO implantation, we observed myocardial damage in the right-sided heart cavities. The present case report illustrates the likelihood that the mechanical chest compression device has limitations that might contribute to inadequate CPR. Therefore, rescuers should consider the efficacy of their chest compression through a continuous hemodynamic monitoring during CPR.

Improved Extracorporeal Cardiopulmonary Resuscitation (ECPR) Outcomes Is Associated with a Restrictive Patient Selection Algorithm.

INTRODUCTION: Out-of-hospital cardiac arrest (OHCA) is a leading cause of mortality. Despite decades of intensive research and several technological advancements, survival rates remain low. The integration of extracorporeal cardiopulmonary resuscitation (ECPR) has been recognized as a promising approach in refractory OHCA. However, evidence from recent randomized controlled trials yielded contradictory results, and the criteria for selecting eligible patients are still a subject of debate. METHODS: This study is a retrospective analysis of refractory OHCA patients treated with ECPR. All adult patients who received ECPR, according to the hospital algorithm, from 2013 to 2021 were included. Two different algorithms were used during this period. A "permissive" algorithm was used from 2013 to mid-2016. Subsequently, a revised algorithm, more "restrictive", based on international guidelines, was implemented from mid-2016 to 2021. Key differences between the two algorithms included reducing the no-flow time from less than three minutes to zero minutes (implying that the cardiac arrests must occur in the presence of a witness with immediate CPR initiation), reducing low-flow duration from 100 to 60 min, and lowering the age limit from 65 to 55 years. The aim of this study is to compare these two algorithms (permissive (1) and restrictive (2)) to determine if the use of a restrictive algorithm was associated with higher survival rates. RESULTS: A total of 48 patients were included in this study, with 23 treated under Algorithm 1 and 25 under Algorithm 2. A significant difference in survival rate was observed in favor of the restrictive algorithm (9% vs. 68%, p < 0.05). Moreover, significant differences emerged between algorithms regarding the no-flow time (0 (0-5) vs. 0 (0-0) minutes, p < 0.05). Survivors had a significantly shorter no-flow and low-flow time (0 (0-0) vs. 0 (0-3) minutes, p < 0.01 and 40 (31-53) vs. 60 (45-80) minutes, p < 0.05), respectively. CONCLUSION: The present study emphasizes that a stricter selection of OHCA patients improves survival rates in ECPR.

Respiratory change in ECG-wave amplitude is a reliable parameter to estimate intravascular volume status.

Electrocardiogram (ECG) is a standard type of monitoring in intensive care medicine. Several studies suggest that changes in ECG morphology may reflect changes in volume status. The "Brody effect", a theoretical analysis of left ventricular (LV) chamber size influence on QRS-wave amplitude, is the key element of this phenomenon. It is characterised by an increase in QRS-wave amplitude that is induced by an increase in ventricular preload. This study investigated the influence of changes in intravascular volume status on respiratory variations of QRS-wave amplitudes (ΔECG) compared with respiratory pulse pressure variations (ΔPP), considered as a reference standard. In 17 pigs, ECG and arterial pressure were recorded. QRS-wave amplitude was measured from the Biopac recording to ensure that in all animals ECG electrodes were always at the same location. Maximal QRS amplitude (ECGmax) and minimal QRS amplitude (ECGmin) were determined over one respiratory cycle. ΔECG was calculated as 100 × [(ECGmax - ECGmin)/(ECGmax + ECGmin)/2]. ΔECG and ΔPP were simultaneously recorded. Measurements were performed at different time points: during normovolemic conditions, after haemorrhage (25 mL/kg), and following re-transfusion (25 mL/kg) with constant tidal volume (10 mL/kg) and respiration rate (15 breath/min). At baseline, ΔPP and ΔECG were both <12 %. ΔPP were significantly correlated with ΔECG (r(2) = 0.89, p < 0.001). Volume loss induced by haemorrhage increased significantly ΔPP and ΔECG. Moreover, during this state, ΔPP were significantly correlated with ΔECG (r(2) = 0.86, p < 0.001). Re-transfusion significantly decreased ΔPP and ΔECG, and ΔPP were significantly correlated with ΔECG (r(2) = 0.90, p < 0.001). The observed correlations between ΔPP and ΔECG at each time point of the study suggest that ΔECG is a reliable parameter to estimate the changes in intravascular volume status and provide experimental confirmation of the "Brody effect."

Combined lactic acidosis and ketoacidosis in a female diabetic patient with severe heart failure.

SGLT2i are now recommended in a wide spectrum of indications including type 2 diabetes (T2DM), heart failure, and chronic kidney disease. This medication class is now available in combination with metformin, which is still a fundamental treatment in patients with T2DM. Despite excellent proven safety profile for both drugs, the expanding use of these agents in clinical practice may lead to an increased incidence of rare side effects, like metformin-associated lactic acidosis (MALA) and euglycemic diabetic ketoacidosis (EDKA), which can be life-threatening. A 58-year-old woman with T2DM and severe heart failure treated by metformin and empagliflozin developed progressive EDKA triggered by fasting that was also complicated by severe acute renal failure and MALA. She was successfully treated with intermittent hemodialysis. This case report highlights the importance of the recognition of rare, but very serious adverse effects due to combined metformin and SGLT2i therapy.

ECMELLA as a bridge to heart transplantation in refractory ventricular fibrillation: A case report.

Background: Extracorporeal membrane oxygenation (ECMO) is an effective cardiorespiratory support technique in refractory cardiac arrest (CA). In patients under veno-arterial ECMO, the use of an Impella device, a microaxial pump inserted percutaneously, is a valuable strategy through a left ventricular unloading approach. ECMELLA, a combination of ECMO with Impella, seems to be a promising method to support end-organ perfusion while unloading the left ventricle. Case summary: The present case report describes the clinical course of a patient with ischemic and dilated cardiomyopathy who presented with refractory ventricular fibrillation (VF) leading to CA in the late postmyocardial infarction (MI) period, and who was successfully treated with ECMO and IMPELLA as a bridge to heart transplantation. Discussion: In the case of CA on VF refractory to conventional resuscitation maneuvers, early extracorporeal cardiopulmonary resuscitation (ECPR) associated with an Impella seems to be the best strategy. It provides organ perfusion, left ventricular unloading, and ability for neurological evaluation and VF catheter ablation before allowing heart transplantation. It is the treatment of choice in cases of end-stage ischaemic cardiomyopathy and recurrent malignant arrhythmias.
