LEVOSIMENDAN to Facilitate Weaning From ECMO in Severe Cardiogenic Shock Patients (LEVOECMO)
In the last decade, venoarterial extracorporeal membrane oxygenation (VA-ECMO) has become the first-line therapy in patients with refractory cardiogenic shock. VA-ECMO provides both respiratory and cardiac support, is easy to insert, even at the bedside, provides stable flow rates, and is associated with less organ failure after implantation compared to large biventricular assist-devices that require open-heart surgery. In patients with potentially reversible cardiac failure (e.g. myocarditis, myocardial stunning post-myocardial infarction, post-cardiotomy or post-cardiac arrest), VA-ECMO might be weaned after a few days of support and used as a bridge to recovery.
Although considered as the ultimate life-saving technology for refractory cardiac failure, veno-arterial ECMO is still associated with severe complications. Specifically, excessive LV afterload and lack of LV unloading under VA-ECMO might induce LV stasis with thrombus formation, pulmonary edema, myocardial ischemia caused by ventricular distension and ultimately increase mortality. ECMO support also exposes to many complications such as infections, hemorrhage or peripheral vascular embolism. These complications are more frequent with prolonged support and are responsible for significant morbidity and mortality, prolonged ICU and hospital stays and higher costs.
Levosimendan, which acts to sensitize myocardial contractile proteins to calcium, improves cardiac contractility without increasing the intracellular calcium concentration. Unlike traditional inotropes such as dobutamine, levosimendan neither increases myocardial oxygen consumption nor impairs diastolic function or possess proarrhythmic effects. It also influences the opening of ATP-dependent potassium channels, including those in vascular smooth muscle cells, leading to coronary, pulmonary, and peripheral vasodilation and antiinflammatory, antioxidative, antiapoptotic, anti-stunning and cardioprotective effects. Additionally, Levosimendan which has a long lasting action (up to 7-9 d), resulting from the formation of active metabolite, may be used as a single 24h perfusion.
In recent preliminary studies, the drug was associated with accelerated weaning from VA-ECMO and even improved survival. Therefore, a multicenter randomized trial with sufficient statistical power is needed in refractory cardiogenic shock patients supported by VA-ECMO to test if the early administration of Levosimendan can facilitate and accelerate VA-ECMO weaning, and ultimately translate in significantly less morbidity, reduced ICU and hospital length of stays and associated costs.

Description
Inclusion Criteria:
Acute cardiogenic shock patient refractory to conventional therapy placed on VA-ECMO support in the preceding 48h.
(The rationale for the early use of levosimendan after VA-ECMO initiation appears strong in patients with refractory cardiogenic shock related to conditions such as acute myocardial infarction, myocarditis, post-cardiac surgery or post-cardiac arrest. Myocardial injuries in these situations share many common pathophysiological features, including ischemia, inflammation and increased oxidative stress leading to extensive myocardial stunning and dysfunction [26-28]. Besides its inotropic properties that might quickly improve myocardial contractility, levosimendan might also exert beneficial antiinflammatory, antioxidative, antiapoptotic, cardioprotective and anti-stunning effects [29-35] that might accelerate cardiac recovery allowing earlier weaning from the support).
- Obtain informed consent from a close relative or surrogate. According to the specifications of emergency consent, randomization without the close relative or surrogate consent could be performed.
Close relative/surrogate/family consent will be asked as soon as possible. The patient will be asked to give his/her consent for the continuation of the trial when his/her condition will allow.
