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.

Purpose of the study: to evaluate the organoprotective effects of veno-arterial extracorporeal membrane oxygenation and intra-aortic balloon pump during high-risk percutaneous coronary intervention in acute coronary syndrome.Materials and methods. Patients required mechanical circulatory support (n=51) were divided into two study groups: patients who received mechanical circulatory support by veno-arterial extracorporeal membrane oxygenation (ECMO) (Group 1, n=29) during high-risk percutaneous coronary intervention, and Group 2 patients who received mechanical circulatory support by intra-aortic balloon pump (IABP) during high-risk percutaneous coronary intervention (Group 2, n=22). The dynamics of instrumental parameters and laboratory markers of organ damage were evaluated by electrocardiography, echocardiography, determining troponin I, creatine phosphokinases and creatinine levels, NGAL, venous blood saturation to compare the organoprotective properties of mechanical circulation support in the intra- and postoperative period.Results. The following values of the parameters were found the next day after the intervention: troponin I — 0.18 (0.1; 2.3) ng/ml in the ECMO group and 1.64 (0.92; 2.36) ng/ml in the IABP group (P=0.045); serum NGAL —139.4 (88.1; 166.7) ng/ml in the ECMO group and 212.3 (102; 279) in the IABP group (P=0.027); renal dysfunction (stages R, I, F according to RIFLE) — 2 (6.8%) observations in the ECMO group and 7 (31.8%) in the IABP group (P=0.021); multiple organ failure (2 or more points according to SOFA) — 3 (10.3%) cases in the ECMO group and 12 (54.5%) in the IABP group (P=0.001).Conclusion. Veno-arterial ECMO in comparison with IABP has a more pronounced organoprotective effect by achieving better hemodynamic stability, which, in turn, prevents hypoxia and the subsequent development of organ dysfunction. In addition, in conditions of veno-arterial ECMO, better completeness and quality of revascularization is ensured, and hospital mortality is also reduced.

Veno-arterial extracorporeal membrane oxygenation is a form of mechanical circulatory support for patients with refractory decompensated heart failure. Blood is drawn from a large vein and pumped back to a large artery, usually a femoral artery through large bore catheters. When the heart recovers, the extracorporeal membrane oxygenation support can be terminated and the catheters are decannulated. The bleeding at the venous side can be controlled by prolonged compression; however, the arteriotomy wound needs to be repaired. Conventionally, the arteriotomy wounds require open vascular repair in the operating theater. The novel application of percutaneous vascular closure devices, which have been commonly used in vascular operations and percutaneous structural heart interventions, could be applied for closure of arteriotomy wounds at the bedside after extracorporeal membrane oxygenation support. The post-close ProGlide (Abbott Vascular) technique was shown to be safe and could potentially save time and manpower. The wounds are much smaller as compared with the conventional open repair and potentially, the chance of wound infection can be reduced. However, the success of percutaneous bedside closure requires careful prior planning and technique training. Backup plans with vascular surgeons’ standby are essential in case of failure of closure. Staffs in the extracorporeal membrane oxygenation centers need to be familiar with the preparation, the procedure as well as the device application technique for successful percutaneous closure. The long learning curve and the limited case load mean that such skills are best trained by simulation scenarios. This article described how this new technique and the team logistics can be trained by simulation.

Introduction: Acute peripartum cardiomyopathy complicated by cardiogenic shock is a rare but life-threatening disease. A prolactin fragment is considered causal for the pathogenesis of peripartum cardiomyopathy. This analysis sought to investigate the role of early percutaneous mechanical circulatory support with micro-axial flow-pumps and/or veno-arterial extracorporeal membrane oxygenation in combination with the prolactin inhibitor bromocriptine in refractory cardiogenic shock complicating peripartum cardiomyopathy. Methods and results: In this single-centre analysis, five peripartum cardiomyopathy patients with refractory cardiogenic shock received mechanical circulatory support with either Impella CP microaxial pump only ( n=2) or in combination with veno-arterial extracorporeal membrane oxygenation ( n=3) in the setting of biventricular failure. All patients were mechanically ventilated. In all cases mechanical circulatory support was combined with bromocriptine therapy and early administration of levosimendan. All patients survived the acute phase of refractory cardiogenic shock. Mechanical circulatory support using a micro-axial pump allowed to significantly reduce catecholamine dosage. Remarkably, early left ventricular support with micro-axial flow-pumps resulted in myocardial recovery whereas delayed Impella (mechanical circulatory support) implantation was associated with poor left ventricular recovery. Conclusion: Mechanical circulatory support in patients with refractory cardiogenic shock complicating peripartum cardiomyopathy was associated with a 30-day survival of 100% and a favourable outcome. Notably, early left ventricular unloading combined with bromocriptine therapy was associated with left ventricular recovery. Therefore, an immediate transfer to a tertiary hospital experienced in mechanical circulatory support in combination with bromocriptine treatment seems indispensable for successful treatment of peripartum cardiomyopathy complicated by cardiogenic shock.

Extracorporeal membrane oxygenation (ECMO) provides essential mechanical circulatory support necessary for survival in infants and children with acute cardiac decompensation. However, ECMO also causes metabolic disturbances, which contribute to total body wasting and protein loss. Cardiac stunning can also occur, which prevents ECMO weaning, and contributes to high mortality. The heart may specifically undergo metabolic impairments, which influence functional recovery. We tested the hypothesis that ECMO alters oxidative metabolism and protein synthesis. We focused on the amino acid leucine and integration with myocardial protein synthesis. We used a translational immature swine model in which we assessed in heart 1) the fractional contribution of leucine (FcLeucine) and pyruvate to mitochondrial acetyl-CoA formation by nuclear magnetic resonance and 2) global protein fractional synthesis (FSR) by gas chromatography-mass spectrometry. Immature mixed breed Yorkshire male piglets ( n = 22) were divided into four groups based on loading status (8 h of normal circulation or ECMO) and intracoronary infusion [13C6,15N]-L-leucine (3.7 mM) alone or with [2-13C]-pyruvate (7.4 mM). ECMO decreased pulse pressure and correspondingly lowered myocardial oxygen consumption (∼40%, n = 5), indicating decreased overall mitochondrial oxidative metabolism. However, FcLeucine was maintained and myocardial protein FSR was marginally increased. Pyruvate addition decreased tissue leucine enrichment, FcLeucine, and Fc for endogenous substrates as well as protein FSR. The heart under ECMO shows reduced oxidative metabolism of substrates, including amino acids, while maintaining 1) metabolic flexibility indicated by ability to respond to pyruvate and 2) a normal or increased capacity for global protein synthesis.

Today, the use of mechanical circulatory support to maintain proper hemodynamics in percutaneous coronary interventions in high-risk patients opens up new avenues for treating such challenging patients. Moreover, it has enabled to treat cases that were once considered overwhelming. The safety and efficacy of using the extracorporeal membrane oxygenation (ECMO) technique is currently being widely studied, however, the literature describes only isolated cases of using this technique when performing percutaneous angioplasty in patients with acute myocardial infarction complicated by cardiogenic shock. In this clinical case, an example of ECMO connection for endovascular myocardial revascularization during percutaneous coronary intervention (PCI) in a patient with myocardial infarction complicated by cardiogenic shock is described.
