The Impact

Introduction: Extracorporeal Cardiopulmonary Resuscitation (ECPR) may achieve ROSC after prolonged CA when conventional cardiopulmonary resuscitation fails. We investigated the impact of ECPR on cardiac hemodynamic recovery and hypothesized, that left ventricular hemodynamic function is impaired in resuscitated hearts. Methods: Adult male Sprague-Dawley rats (500 g, n=36) were subjected to 6 or 8 min of ventricular fibrillation CA, thereafter resuscitated with ECPR (open reservoir, roller pump, membrane oxygenator, draining catheter in the right jugular vein, inflow catheter in the right femoral artery; custom made bypass system), mechanical ventilation and drugs (epinephrine, bicarbonate, heparin). After defibrillation and ROSC, rats survived for 14 days and were compared to 7 sham animals. The hearts were isolated and mounted onto an erythrocyte-perfused, isolated working heart (WH) system. Cardiac output, left ventricular systolic pressure (LVSP), coronary flow and pressure-volume (P-V) relationships (by increasing the afterload in 10 mmHg increments) were measured. Myocardium of all rats was evaluated pathohistological in hematoxylin-eosin staining. Results: ROSC was achieved in 18 animals after 6 min of CA, of which 10 survived 14 d and 7 were investigated in WH, in 8 min CA group 15 achieved ROSC of which 5 survived to 14 d and 2 were investigated in WH and compared to the hearts of 7 sham animals. At defined afterload (60 mm Hg; baseline) there was no difference in cardiac hemodynamics between sham and 6 min CA group. In contrast, 8 min CA rats showed a tendency towards decrease in cardiac output and LVSP compared to sham animals. Notably, both CA groups showed impaired P-V loop relationship and subsequently less tolerance to hemodynamic stress. Histologically all 8 min CA rats showed multiple foci of myocardial scarring. Conclusions: CA led to impaired left ventricular hemodynamics in 8 min CA rats resuscitated with ECPR. In addition, hearts were more vulnerable to hemodynamic stress after successful resuscitation. For investigating the effects of future therapy approaches during and after resuscitation from CA on the heart function, isolated WH might be a promising approach in resuscitation research.

The Impact

Background: We evaluated critically ill patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR) due to cardiac arrest (CA) with respect to baseline characteristics and laboratory assessments, including lactate and lactate clearance for prognostic relevance. Methods: The primary endpoint was 30-day mortality. The impact on 30-day mortality was assessed by uni- and multivariable Cox regression analyses. Neurological outcome assessed by Glasgow Outcome Scale (GOS) was pooled into two groups: scores of 1–3 (bad GOS score) and scores of 4–5 (good GOS score). Results: A total of 93 patients were included in the study. Serum lactate concentration (hazard ratio (HR) 1.09; 95% confidence interval (CI) 1.04–1.13; p < 0.001), hemoglobin, (Hb; HR 0.87; 95% CI 0.79–0.96; p = 0.004), and catecholamine use were associated with 30-day-mortality. In a multivariable model, only lactate clearance (after 6 h; OR 0.97; 95% CI 0.94–0.997; p = 0.03) was associated with a good GOS score. The optimal cut-off of lactate clearance at 6 h for the prediction of a bad GOS score was at ≤13%. Patients with a lactate clearance at 6 h ≤13% evidenced higher rates of bad GOS scores (97% vs. 73%; p = 0.01). Conclusions: Whereas lactate clearance does not predict mortality, it was the sole predictor of good neurological outcomes and might therefore guide clinicians when to stop ECPR.

The Impact

Extracorporeal cardiopulmonary resuscitation (ECPR) remains a promising treatment for pediatric patients in cardiac arrest unresponsive to traditional cardiopulmonary resuscitation. With venoarterial extracorporeal support, blood is drained from the right atrium, oxygenated through the extracorporeal circuit, and transfused back to the body, bypassing the heart and lungs. The use of artificial oxygenation and perfusion thus provides the body a period of hemodynamic stability, while allowing resolution of underlying disease processes. Survival rates for ECPR patients are higher than those for traditional cardiopulmonary resuscitation (CPR), although neurological outcomes require further investigation. The impact of duration of CPR and length of treatment with extracorporeal membrane oxygenation vary in published reports. Furthermore, current guidelines for the initiation and use of ECPR are limited and may lead to confusion about appropriate use of this support. Many ethical concerns arise with this advanced form of life support. More often than not, the dilemma is not whether to withhold ECPR, but rather when to withdraw it. Although clinicians must decide if ECPR is appropriate and when further intervention is futile, the ultimate burden of choice is left to the patient’s caregivers. Offering support and guidance to the patient’s family as well as the patient is essential.

Refractory Cardiac Arrest

Abstract Background: Extracorporeal cardiopulmonary resuscitation (E-CPR) using venoarterial extracorporeal membrane oxygenation (VA-ECMO) is a novel lifesaving method for refractory cardiac arrest (CA). However, VA-ECMO increases damaged left ventricular (LV) afterload. The percutaneous microaxial pump Impella can reduce LV preload with simultaneous circulatory support, which may have a significant effect on clinical outcome by concomitant use of VA-ECMO and IMPELLA (ECPELLA). In the current retrospective cohort study, we assessed factors affecting the outcome of CA patients who underwent E-CPR.Method: We retrospectively reviewed 149 consecutive CA patients with E-CPR from January 2012 through December 2020 in our institute. Patients were divided into three groups: ECEPLLA (n=29), IABP + VA-ECMO (n=78), and single VA-ECMO (n=42). We assessed 30-day survival and neurological outcome using cerebral performance categories (CPCs).Results: There were no significant differences in age, sex, out-of-hospital CA, or acute coronary syndrome among the groups. ECPELLA showed the highest cumulative 30-day survival (ECPELLA: 55%, IABP + VA-ECMO: 23%, VA-ECMO: 9.5; p=0.001) and the rates of CPC score 1 or 2 (ECPELLA: 31%, IABP + VA-ECMO: 13%, VA-ECMO: 7%; p=0.02). Multivariate analysis revealed that age (hazard ratio [HR], 1.30, 95% confidence interval [CI], 1.13-1.52, P=0.005) and time from CA to ECMO support (HR, 1.22, 95% CI, 1.13-1.31, P<0.0001) and ECPELLA (HR, 0.46, 95% CI, 0.24-0.88, P=0.02) were significantly associated with the clinical outcome.Conclusion: Earlier initiation of E-CPR is critical to improve patient survival and neurological outcome. Additional Impella support, ECPELLA, appears to significantly improve the clinical outcome.

Introduction: For patients who receive extracorporeal cardiopulmonary resuscitation (ECPR), the relationship between post-resuscitation management and survival is unknown. Additionally, it is not known if management varies between centers, and if this variation and hospital case volume, are associated with survival. Hypothesis: There is center level variability in post-resuscitation management for ECPR patients. This variability, and hospital annual case volume, are associated with survival. Methods: We performed an observational study of 4,296 adults who received ECPR from the Extracorporeal Life Support Organization registry from 2014 until 2019. We examined clinical variables within the first 24 hours after arrest, and hospital annual ECPR volume. The primary outcome was case-mix adjusted survival at hospital discharge, adjusting for factors previously associated with survival after cardiac arrest or extracorporeal membrane oxygenation (ECMO). Mixed effects regression models were used to account for clustering of outcomes by center. Case volume was stratified into low (<6 cases/year), medium (6-12 cases/year) and high (>12 cases/year). Results: Patient-level clinical variables after cardiac arrest, varied widely across individual hospitals, including the use of percutaneous coronary intervention (PCI), mechanical venting of the left ventricle, and the use of inotropic medications. Increased ECMO circuit blood flow at 4 hours was associated with survival (OR 1.14 per liter per minute of flow [95% CI 1.04 to 1.24];p=0.004). After 24 hours of ECMO, increased arterial pulsatility (OR 1.44 [95% CI 1.32 to 1.58]; p<0.001), the placement of a distal perfusion catheter (OR 1.79 [95% CI 1.19 to 2.67]; p=0.005), and the placement of a mechanical left ventricular vent (OR 1.37 [95% CI 1.07 to 1.76]; p=0.012) were all significantly associated with survival. There was a nonsignificant association of the use of PCI after ECMO cannulation with survival (OR 1.31 [95% CI 0.998 to 1.91]; p=0.051). High case volume was not associated with survival (OR 1.32 [95% CI 0.98 to 1.78];p=0.072). Conclusions: Clinical management of ECPR patients varies across hospitals. These clinical variables and therapies are associated with survival, however center volume is not.

Hospital Cardiac Arrest

A 68-year-old male with a witnessed out-of-hospital cardiac arrest while jogging who was managed with extracorporeal cardiopulmonary resuscitation (ECPR) is presented. The patient was found to be in refractory ventricular fibrillation by emergency medical service personnel and underwent advanced cardiac life support (ACLS) protocol with placement of an automated chest compression device. He was emergently transported to the cardiac catheterization laboratory. Due to refractory ventricular fibrillation, he was placed on venoarterial extracorporeal membranous oxygenation (VA-ECMO). Coronary angiography at that time showed nonobstructive coronary artery disease. Management with VA-ECMO and other supportive measures were continued for 5 days, after which a cardiac magnetic resonance imaging was performed with findings consistent with acute myocarditis. His condition substantially improved, and he was discharged from the hospital with good neurologic and functional status. Fulminant myocarditis is often fatal, but aggressive supportive measures with novel ECPR protocols may result in recovery, as it happened in this case.

Abstract Introduction Paradoxical cerebral infarction is a mechanism of acute ischemic stroke; however, definitive images to diagnose paradoxical embolism are not often obtained. We report a case of paradoxical cerebral embolism complicated with cardiac arrest due to massive pulmonary embolism. Case report A 40-year-old man presented due to sudden-onset chest pain, and was admitted to our hospital. He was restless and had cold sweat; we could not measure blood pressure. Electrocardiography showed wide QRS complex with right bundle branch block, and T wave inversion in leads V1 and III. Transthoracic echocardiography showed diffuse severe left ventricular hypokinesis, with slightly better inferior wall motion compared to other segments. Few minutes after arriving, he experienced cardiac arrest; chest compression was initiated. He was transported to the catheter laboratory, and veno-arterial extracorporeal membrane oxygenation was initiated subsequently. To diagnose the cause of arrest, we performed coronary angiography, which revealed no occluded coronary artery. Pulmonary angiograms showed bilateral proximal pulmonary artery occlusion with massive thrombi (panel A). Surgical embolectomy was performed after cardiac team discussion. After ICU admission post-surgery, pericardial effusion was increased, and the blood drained continuously from the chest tube; a large amount of blood transfusion was required. Reopen chest haemostasis was utilised. After the second ICU admission, anisocoria was observed; subsequent computed tomography showed low density and midline shift in almost the entire left cerebral hemisphere (Panel B). Carotid duplex ultrasound revealed a large thrombus saddled at the left carotid artery bifurcation (Panel C and D). We rechecked the transthoracic echocardiogram at arrival to reveal the cause of the cerebral infarction, which showed the thrombus to be at the ascending aorta (Panel E). We thought that the thrombi had moved from the lower limb to the right atrium. The massive pulmonary embolism increased the pulmonary artery and right atrial pressure, resulting in the lower pressure of the left atrium compared to that of the right atrium. The thrombi passed through the patent foramen ovale into the left atrium, moved into the left ventricle, and embolised the left internal carotid artery (Panel F). He expired due to severe neurologic injury from brain herniation. Conclusion In this case, although the pulmonary embolism was massive and led to cardiac arrest, the deteriorated haemodynamics improved by extracorporeal cardiopulmonary resuscitation and surgical embolectomy. However, we could not rescue the patient because of the severe neurological injury due to paradoxical embolism. Paradoxical cerebral infarction in pulmonary embolism is rare; however, we should pay careful attention to early detection of paradoxical cerebral infarction in pulmonary embolism and treatment for return of the patient to the former lifestyle.
