Abstract OBJECTIVES Short-term mechanical circulatory support is a life-saving treatment for acute cardiogenic shock (CS). This multicentre study investigates the preoperative predictors of 30-day mortality in CS patients treated with Impella 5.0 and 5.5 short-term left ventricular assist devices. METHODS Data of patients in CS (n = 70) treated with the Impella 5 (n = 63) and 5.5 (n = 7) in 2 centres in Berlin between October 2016 and October 2019 were collected retrospectively. RESULTS CS was caused by acute myocardial infarction (n = 16), decompensated chronic heart failure (n = 41), postcardiotomy syndrome (n = 5) and acute myocarditis (n = 8). Before implantation 12 (17%) patients underwent cardiopulmonary resuscitation and 32 (46%) patients were ventilated. INTERMACS level 1, 2 and 3 was established in 35 (50%), 29 (41%) and 6 (9%) of patients, respectively. The mean preoperative lactate level was 4.05 mmol/l. The median support time was 7 days (IR= 4–15). In 18 cases, the pump was removed for myocardial recovery, in 22 cases, durable left ventricular assist devices were implanted, and 30 patients died on support. The overall 30-day survival was 51%. Statistical analysis showed that an increase in lactate per mmol/l [odds ratio (OR) 1.217; P = 0.015] and cardiopulmonary resuscitation before implantation (OR 16.74; P = 0.009) are predictors of 30-day survival. Based on these data, an algorithm for optimal short-term mechanical circulatory support selection is proposed. CONCLUSIONS Impella treatment is feasible in severe CS. Severe organ dysfunction, as well as the level and duration of shock predict early mortality. An algorithm based on these parameters may help identify patients who would benefit from Impella 5+ support.

Heart failure is a leading cause of morbidity and mortality in the United States. Treatment of this condition increasingly involves mechanical circulatory support devices. Even with optimal medical therapy and use of simple cardiac devices, heart failure often leads to reduced quality of life and a shortened life span, prompting exploration of more advanced treatment approaches. Left ventricular assist devices constitute an effective alternative to cardiac transplantation. These devices are not without complications, however, and their use requires careful cooperative management by the patient’s cardiology team and primary care provider. Left ventricular assist devices have undergone many technological advancements since they were first introduced, and they will continue to evolve. This article reviews the history of different types of left ventricular assist devices, appropriate patient selection, and common complications in order to increase health professionals’ familiarity with these treatment options.

Abstract Left ventricular assist devices (LVAD) are increasingly being used as destination therapy in patients with Stage D heart failure. It has been reported that a majority of patients who receive a durable LVAD (dLVAD) present in cardiogenic shock due to decompensated heart failure (ADHF‐CS). As it stands, there is no consensus on the optimal management strategy for patients presenting with ADHF. Bridging with intra‐aortic balloon pumps (IABPs) continues to be a therapeutic option in patients with hemodynamic instability due to cardiogenic shock. The majority of data regarding the use of IABP in cardiogenic shock come from studies in patients presenting with acute myocardial infarction with cardiogenic shock and demonstrates that there is no benefit of routine IABP use in this patient population. However, the role of IABPs as a bridge to dLVAD in ADHF‐CS has yet to be determined. The hemodynamic changes seen in acute myocardial infarction with cardiogenic shock are known to be different and more acutely impaired than those presenting with ADHF‐CS as evidenced by differences in pressure/volume loops. Thus, data should not be extrapolated across these 2 very different disease processes. The aim of this review is to describe results from contemporary studies examining the use of IABPs as a bridge to dLVAD in patients with ADHF‐CS. Retrospective evidence from large registries suggests that the use of IABP as a bridge to dLVAD is feasible and safe when compared with other platforms of temporary mechanical circulatory support. However, there is currently a paucity of high‐quality evidence examining this increasingly important clinical question.
