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.

Myocardial Wall Stress

Acute myocardial infarction (AMI) can progress to cardiogenic shock and mechanical complications. When extracorporeal membrane oxygenation (ECMO) is applied to a patient with AMI with cardiogenic shock and mechanical complications, left ventricular (LV) decompression is an important recovery factor because LV dilation increases myocardial wall stress and oxygen consumption. The authors present the case of a 72-year-old man with AMI and LV dilation who developed cardiogenic shock and papillary muscle rupture and who was treated successfully by ECMO with a left atrial venting.

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.

Unadjusted Analysis

Mechanical circulatory support (MCS) devices are effective tools in managing refractory cardiogenic shock (CS). Data comparing veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and IMPELLA® are however scarce. We aimed to assess outcomes of patients implanted with these two devices and eligible to both systems. From 2004 to 2020, we retrospectively analyzed 128 patients who underwent VA-ECMO or IMPELLA® in our institution for refractory left ventricle (LV) dominant CS. All patients were eligible to both systems: 97 patients were first implanted with VA-ECMO and 31 with IMPELLA®. The primary endpoint was 30-day all-cause death. VA-ECMO patients were younger (52 vs. 59.4, p = 0.006) and had a higher lactate level at baseline than those in the IMPELLA® group (6.84 vs. 3.03 mmol/L, p < 0.001). Duration of MCS was similar between groups (9.4 days vs. 6 days in the VA-ECMO and IMPELLA® groups respectively, p = 0.077). In unadjusted analysis, no significant difference was observed between groups in 30-day mortality: 43.3% vs. 58.1% in the VA-ECMO and IMPELLA® groups, respectively (p = 0.152). After adjustment, VA-ECMO was associated with a significant reduction in 30-day mortality (HR = 0.25, p = 0.004). A higher rate of MCS escalation was observed in the IMPELLA® group: 32.3% vs. 10.3% (p = 0.003). In patients eligible to either VA-ECMO or IMPELLA® for LV dominant refractory CS, VA-ECMO was associated with improved survival rate and a lower need for escalation.

Background: There is paucity of data regarding radiofrequency ablation for ventricular tachycardia (VT) in patients with cardiogenic shock and concomitant VT refractory to antiarrhythmic drugs on mechanical support. Methods: Patients undergoing VT ablation at our center were enrolled in a prospectively maintained registry and screened for the current study (2010–2017). Results: All 21 consecutive patients with cardiogenic shock and concomitant refractory ventricular arrhythmia undergoing bailout ablation due to inability to wean off mechanical support were included. Median age was 61 years, 86% were men, median left ventricular ejection fraction was 20%, 81% had ischemic cardiomyopathy, and PAINESD score was 18±5. The type of mechanical support in place before the procedure was intra-aortic balloon pump in 14 patients (67%), Impella CP in 2, extracorporeal membrane oxygenation in 2, extracorporeal membrane oxygenation and intra-aortic balloon pump in 2, and extracorporeal membrane oxygenation and Impella CP in 1. Endocardial voltage maps showed myocardial scar in 19 patients (90%). The clinical VTs were inducible in 13 patients (62%), whereas 6 patients had premature ventricular contraction–induced ventricular fibrillation/VT (29%), and VT could not be induced in 2 patients (9%). Activation mapping was possible in all 13 with inducible clinical VTs. Substrate modification was performed in 15 patients with scar (79%). After ablation and scar modification, the arrhythmia was noninducible in 19 patients (91%). Seventeen (81%) were eventually weaned off mechanical support successfully, but 6 (29%) died during the index admission from persistent cardiogenic shock. Patients who had ventricular arrhythmia and cardiogenic shock on presentation had a trend toward lower in-hospital mortality compared with those who presented with cardiogenic shock and later developed ventricular arrhythmia. Conclusions: Bailout ablation for refractory ventricular arrhythmia in cardiogenic shock allowed successful weaning from mechanical support in a large proportion of patients. Mortality remains high, but the majority of patients were discharged home and survived beyond 1 year.
