Filter by:The goal of this study is to describe the use of ECMO (Extracorporeal Membrane Oxygenation) in the pregnant or peripartum patient.
The investigation of patient characteristics and prognostic factors of the patients presented with cardiogenic shock (CS) will guide us to identify the better management strategy for these critically ill patients. Mechanical circulatory support (MCS) may improve the prognosis of some of severe subset of CS patients. The better understanding of the indications of initiation and weaning of MCS will improve the prognosis of critically ill CS patients.
Cardiogenic shock is a condition of low cardiac output that represents the end of a progressive deterioration of cardiac function. The main cause is ischemic heart disease but there are several causes of non-ischemic nature including sepsis. Sepsis is characterized by a picture of organ dysfunction caused by an altered response of the body to an infection. Its most serious form is septic shock, defined as a picture of sepsis in which the underlying abnormalities in the cardiovascular system and cellular metabolism are such as to increase mortality. An organ failure correlates directly with the function of others and this interdependence is especially evident when a cardiovascular failure is established. 3 Cardiac dysfunction in sepsis can be defined as that of a syndrome characterized by low cardiac output not related to myocardial ischemia. The use of levosimendan in cardiogenic shock during sepsis was first described in a 2005 case report. Since then there have been small studies and other case reports that have shown improvements in right and left ventricular contractility, ventricular coupling, cardiopulmonary performance, global oxygen transport, renal and splanchnic perfusion when compared to dobutamine and placebo. Other beneficial effects of this drug have emerged, including an anti-inflammatory, antioxidant and antiapoptotic action with a possible protection from ischemia-reperfusion damage. The present study aims to evaluate the correct use of levosimendan, after the occurrence of cardiogenic shock on a low cardiac index has been ascertained, with the aim of weaning from inotropic drugs in infusion.
The project's main goal is to collect baseline clinical and procedural data as well as to assess clinical outcomes for all patients undergoing ECMO or Impella implantation at all included sites. All patients undergoing ECMO and/or IMPELLA implantation will be prospectively registered. Device use is according to the decision of the treating physician and independent of this registry.
Veno-arterial extra-corporeal membrane oxygenation (VA-ECMO) is used as a rescue strategy for patients in acute hemodynamic deterioration such as cardiogenic shock and cardiopulmonary arrest with severe pulmonary congestion. VA ECMO is the fastest way to stabilize a patient with cardiogenic shock and improve end-organ perfusion. However, one of the major disadvantages of peripheral VA-ECMO is that it provides no left ventricular unloading and increases left ventricular (LV) afterload secondary to the retrograde blood flow. Therefore, LV wall tension and myocardial oxygen demand may actually increase in the setting of VA ECMO. The Impella® device is a miniature rotary blood pump which can be inserted retrograde across the aortic valve. In this configuration, it withdraws blood from the LV and ejects it into the ascending aorta. It unloads the left ventricle, reducing LV wall tension and myocardial oxygen demand and increasing myocardial blood flow. The Impella® 5.0 is an FDA approved pump designed for intermediate support in patients with severe, cardiogenic shock. The axillary positioning allows for early extubation and ambulation and is more stable than groin placement. In present practice, the decision to place an Impella® pump in VA-ECMO patients is based on the perceived need for direct LV unloading or when a bridge device is required to transition off ECMO support. Patients with peripheral VA ECMO are managed with inotropic agents at the beginning and once patients develop pulmonary edema mechanical LV unloading is considered electively. The advantage of LV unloading with Impella® has been demonstrated in recent studies. We also reported that concomitant implantation of Impella® with VA ECMO for LV unloading resulted in improved survival and recovery of ventricular performance in patients with cardiogenic shock. Compared to delayed elective LV unloading, early LV unloading could lead to decreased pulmonary edema, improved oxygenation delivery to the myocardium, increased chance of LV recovery and improved survival. The objective of this prospective study is to assess whether the early direct ventricular unloading using axillary Impella® leads to higher rates of cardiac recovery, defined as survival free from mechanical circulatory support, heart transplantation or inotropic support at thirty days, compared with the conventional, elective placement of Impella® after developing significant pulmonary congestion.
Post-cardiotomy cardiogenic shock (PCCS) occurs in 2-6% of patients undergoing cardiac surgery, and 1% of cardiac surgery patients will require mechanical circulatory support using Veno-Arterial ExtraCorporeal Membrane Oxygenation (VA-ECMO). Acute Kidney Injury is a frequent complication in this population and negatively impacts the survival. We aimed to determine whether the timing of ECMO implantation influence the renal prognosis of these patients.
Venoarterial extracorporeal membrane oxygenation (VA ECMO)—also referred to as extracorporeal life support—is a form of temporary mechanical circulatory support and simultaneous extracorporeal gas exchange. The objective of this observational, cohort study is to evaluate the short-term and long-term outcomes of patients with VA ECMO.
Cardiogenic shock (CS) mortality remains high (40%). Despite their frequent use, few clinical outcome data are available to guide the initial selection of vasoactive drug therapies in patients with CS. Based on experts' opinions, the combination of norepinephrine-dobutamine is generally recommended as a first line strategy. Inotropic agents increase myocardial contractility, thereby increasing cardiac output. Dobutamine is commonly recommended to be the inotropic agent of choice and levosimendan is generally used following dobutamine failure. It may represent an ideal agent in cardiogenic shock, since it improves myocardial contractility without increasing cAMP or calcium concentration. At present, there are no convincing data to support a specific inotropic agent in patients with cardiogenic shock. Our hypothesis is that the early use of levosimendan, by enabling the discontinuation of dobutamine, would accelerate the resolution of signs of low cardiac output and facilitate myocardial recovery.
Cardiogenic shock is a serious medical condition with high mortality and morbidity. This trial assesses safety, tolerability and efficacy of Adrecizumab on top of standard of care in patients with cardiogenic shock.
Temporary cardiac support by VA-ECLS can lead to lower limb ischemia. The aim of this study is to evaluate a multi-modal strategy (physical examination, NIRS monitoring and angiography through the reperfusion canula) of lower limb surveillance.
