Abstract Background The clinical spectrum of severe fever with thrombocytopenia syndrome (SFTS) is wide, which can range from fever to multiple organ failure. Conservative therapy plays a key role in the treatment of SFTS. However, severe cases of SFTS, such as fulminant myocarditis, may require mechanical hemodynamic support. Case presentation This report presents a case of a 59-year old woman diagnosed with SFTS by reverse-transcription polymerase chain reaction. The patient had no initial symptoms of cardiac involvement and rapidly developed hemodynamic instability 3 days after hospitalization. She suffered from chest pain and had elevated cardiac enzymes. In the absence of atrio-ventricular conduction abnormalities, left ventricular dysfunction, and coronary artery abnormalities by coronary angiography, she was diagnosed with fulminant myocarditis. At that time, her pulse rate nearly dropped to 0 bpm and she developed near complete akinesia of the heart despite vasopressor administration. Veno-arterial extracorporeal membrane oxygenation (ECMO) was initiated with other supportive measures and she fully recovered after 21 days. Conclusions This case indicates that SFTS can cause fulminant myocarditis even without evidence of cardiac involvement at presentation. When symptoms and/or signs of acute heart failure develop in patients with SFTS, myocarditis should be suspected and the patient should be promptly evaluated. Additionally, mechanical hemodynamic support like ECMO can be a lifesaving tool in the treatment of fulminant myocarditis.

Background: Many clinicians do not know under what exact conditions extracorporeal membrane oxygenation (ECMO) can get the best results. In this study, we explored the optimal indications for ECMO in patients with refractory cardiogenic shock. Methods: From October 2014 to November 2019, 23 patients with refractory cardiogenic shock were treated with ECMO in our hospital, including 11 cases with acute left anterior myocardial infarction, 3 with acute left inferior and right ventricular myocardial infarction, and 9 with fulminant myocarditis. These cases were divided into survivors (n = 10) and nonsurvivors (n = 13), and the clinical data of the 2 groups were compared. Results: The weaning rate of ECMO was 60.9%. The discharge survival rate was 43.5%. There were significant differences in age, sequential organ failure assessment (SOFA) score, vasoactive-inotropic (VIS) score, lactic acid concentrations, primary disease, and smoking history between survivors and nonsurvivors before ECMO (P < .05). There were significant differences in blood pressure (systolic and diastolic), oxygen partial pressure, and left ventricular ejection fraction between survivors and nonsurvivors 1 day before the removal of ECMO (P < .05). Conclusions: The reversibility of the primary disease causing refractory cardiogenic shock is critical to the survival rate of ECMO. Etiological treatment is essential, and extra attention should be paid to the use of ECMO in patients with irreversible primary disease. ECMO should be regarded as a first aid device and is not suitable for long-term cardiac assistance; left ventricular assist or heart transplantation is a better option.

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.

Abstract A 29-year-old woman presented to the emergency department with the acute onset of palpitations, shortness of breath, and haemoptysis. She reported having an abortion (56 days of pregnancy) 1 week before admission because of hyperthyroidism diagnosis during pregnancy. The first diagnoses considered were cardiomyopathy associated with hyperthyroidism, acute left ventricular failure, and hyperthyroidism crisis. The young woman’s cardiocirculatory system collapsed within several hours. Hence, venoarterial extracorporeal membrane oxygenation (VA ECMO) was performed for this patient. Over the next 3 days after ECMO was established, repeat transthoracic echocardiography showed gradual improvements in biventricular function, and later the patient recovered almost completely. The patient’s blood pressure increased to 230/130 mm Hg when the ECMO catheter was removed, and then the diagnosis of phaeochromocytoma was suspected. Computed tomography showed a left suprarenal tumour. The tumour size was 5.8 cm × 5.7 cm with central necrosis. The vanillylmandelic acid concentration was 63.15 mg/24 h. Post-operation, pathology confirmed phaeochromocytoma. To our knowledge, this is the first case report of a patient with cardiogenic shock induced by phaeochromocytoma crisis mimicking hyperthyroidism which was successfully resuscitated by VA ECMO.

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.

Introduction: Extracorporeal membrane oxygenation (ECMO) supports hemodynamics in cardiogenic shock (CS) at the expense of left ventricular (LV) overload. LV assist device (LVAD) also supports hemodynamics, whereas LVAD unloads LV. Therefore, the combination of ECMO and LVAD would augment hemodynamic support and unload LV. We hypothesized that the combination therapy in acute myocardial infarct (AMI) in CS could synergistically improve hemodynamics and unload LV, which, in turn, reduces infarct size. Methods: In protocol 1, we ligated coronary arteries and created AMI with CS in 5 mongrel dogs (15.1±0.3 kg). We transvascularly introduced Impella CP into LV. We kept the ECMO flow constant at 1.8L/min. We compared hemodynamics and the LV pressure-volume area (PVA, an index of LV oxygen consumption) under 3 conditions; Control, ECMO, and ECMO+Impella (ECPELLA) in each dog. In protocol 2 (n=15), we ligated coronary arteries for 180 min and then reperfused. We activated Impella CP and/or ECMO from 60 min after the coronary ligation to the end of the experiment. We allocated dogs into 3 groups, no support (Control), ECMO, and ECPELLA and compared infarct size at 180 min after reperfusion among 3 groups. Results: In protocol 1, both ECMO and ECPELLA increased arterial pressure compared to Control (Control: 63±9, ECMO: 88±10 and ECPELLA: 97±18 mmHg, p < 0.05), and resolved the CS status. ECPELLA strikingly reduced PVA by 83% relative to Control (1500±326, 2038±357 and 258±182 mmHg*ml, p<0.001). In protocol 2, ECPELLA markedly reduced the infarct size (15±8%) compared to Control (53±7%, p<0.05) and ECMO (39±10%, p<0.05). Conclusions: ECPELLA before reperfusion markedly improved hemodynamics, reduced PVA, and limited infarct size in a dog model of MI with CS. ECPELLA could prevent ECMO-induced LV overload and synergistically exert powerful anti-infarct effects in AMI with CS.
