BACKGROUND: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is a widely used form of mechanical circulatory support in patients with refractory cardiogenic shock. A common drawback of this modality is a resultant increase in left ventricular afterload. OBJECTIVES: The purpose of this meta-analysis was to examine the efficacy and safety of left ventricular unloading strategies during VA-ECMO in adult patients with cardiogenic shock. METHODS: The authors performed a systematic search of studies examining left ventricular unloading during VA-ECMO in Medline, EMBASE, and the Cochrane library...

Contemporary studies of long-term outcomes in children supported on extracorporeal membrane oxygenation (ECMO) in the United States are limited. We enrolled 99 ECMO patients between July 2010 and June 2015 in a two-center prospective observational study that included neurologic and neuropsychologic evaluation at 6 and 12 months, using standardized outcome measures. Pre-ECMO, 20 (20%) had a pre-existing neurologic diagnosis, 40 (40%) had cardiac arrest, and 10 of 47 (21%) children with neuroimaging had acute abnormal findings...

The pre-listing variables essential for creating an accurate heart transplant allocation score based on survival are unknown. To identify these we studied mortality of adults on the active heart transplant waiting list in the Scientific Registry of Transplant Recipients database from January 1, 2004-August 31, 2015. There were 33,069 candidates awaiting heart transplantation: 7,681 UNOS Status 1A, 13,027 Status 1B, and 12,361 Status 2. During a median waitlist follow-up of 4.3 months, 5514 candidates died. Variables of importance for waitlist mortality were identified by machine learning using Random Survival Forests...

PURPOSE: Children with complex congenital heart disease (CHD) experience high incidence of perioperative seizures. Population-based studies also report high epilepsy co-morbidity in CHD. Given the increasing survival of patients with CHD and the interference of seizures and epilepsy with the long-term outcomes, characterizing them in this population is of high relevance. This study investigated the incidence and risk factors of perioperative clinical seizures (CS) and epilepsy in a prospective cohort of children with complex CHD who underwent cardiac surgery...

Peripheral veno-arterial extra corporeal membrane oxygenation (VA-ECMO) is an established technique for short-to-medium support of patients with severe cardiac failure. However, in patients with concomitant respiratory failure, the residual native circulation will provide deoxygenated blood to the upper body, and may cause differential hypoxemia of the heart and brain. In this paper, we present a general computational framework for the identification of differential hypoxemia risk in VA-ECMO patients. A range of different VA-ECMO patient scenarios for a patient-specific geometry and vascular resistance were simulated using transient computational fluid dynamics simulations, representing a clinically relevant range of values of stroke volume and ECMO flow...

BACKGROUND: Salvage rates for patients requiring extracorporeal membrane oxygenation (ECMO)due to acute cardiogenic shock remain poor due to difficulties in decision making on optical timing of ECMO removal or conversion to ventricular assist devices( VAD). METHOD: From 2005 to 2018, 37 patients supported with ECMO due to acute circulatory deterioration were referred to our department for implantation of VAD. Their outcomes were analyzed using multi-variate analysis to assess the risk factors of VAD implantation, and we adopted a new decision-tree to improve the outcomes...

BACKGROUND: The efficacy of venovenous extracorporeal membrane oxygenation (ECMO) in patients with severe acute respiratory distress syndrome (ARDS) remains controversial. METHODS: In an international clinical trial, we randomly assigned patients with very severe ARDS, as indicated by one of three criteria - a ratio of partial pressure of arterial oxygen (Pao2 ) to the fraction of inspired oxygen (Fio2 ) of less than 50 mm Hg for more than 3 hours; a Pao2 :Fio2 of less than 80 mm Hg for more than 6 hours; or an arterial blood pH of less than 7...

Blood pressure management is crucial for patients on veno-arterial extracorporeal membrane oxygenation (VA ECMO). Lower pressure can lead to end-organ malperfusion, whereas higher pressure may compete with ECMO flow and cardiac output. The impact of mean arterial pressure (MAP) on outcomes of patients on VA ECMO was evaluated. Patients who were supported on VA ECMO from September 2010 to March 2016 were retrospectively analyzed for average MAP throughout their course on ECMO, excluding the first and last day...

BACKGROUND: Acute cerebral complications (ACC) of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) are associated with poor long-term neurologic outcome. We described the role of rSO2 monitoring in detecting ACC and desaturations and their relationship with poor outcome when employing VA-ECMO. METHODS: Retrospective analysis of patients monitored by cerebral frontal near-infrared spectroscopy (NIRS) (CAS Medical Systems Inc., Branford, CT, USA) during VA-ECMO (November 2008-December 2015)...

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) has been used for refractory cardiogenic shock; however, it is associated with increased left ventricular afterload. Outcomes associated with the combination of a percutaneous left ventricular assist device (Impella) and VA-ECMO remains largely unknown. We retrospectively reviewed patients treated for refractory cardiogenic shock with VA-ECMO (2014-2016). The primary outcome was all-cause mortality within 30 days of VA-ECMO implantation. Secondary outcomes included duration of support, stroke, major bleeding, hemolysis, inotropic score, and cardiac recovery...

OBJECTIVES: Ethical and health care economic concerns surround the use of venous-arterial extracorporeal membrane oxygenation (VA-ECMO) in elderly patients. Patients requiring VA-ECMO are often in critical condition and the decision to cannulate is time-sensitive. We investigated the relationship between age and VA-ECMO outcomes to better inform this decision. METHODS: This is a retrospective study of 355 patients placed on VA-ECMO between March 2007 and August 2016 at our institution...

The majority of patients who suffer acute ischemic stroke (AIS) from large vessel occlusion are at a significant risk for disability or death. Because patients on veno-arterial extracorporeal membrane oxygenation (VA ECMO) are therapeutically anticoagulated, intravenous recombinant tissue plasminogen activator is contraindicated. For AIS management, these patients must undergo emergent intra-arterial therapy. Presented is a patient on VA ECMO who subsequently suffered a large vessel embolic stroke requiring emergent surgical intervention...

The evolution of devices for mechanical circulatory support (MCS), including ventricular assist devices (VADs) for patients with heart failure and extracorporeal membrane oxygenation (ECMO) for patients with acute cardiac or respiratory failure, has improved survival for subsets of critically ill children and adults. The devices are intricate and complex, allowing blood to bypass the heart or lungs (or both). As blood flows through these artificial devices, normal hemostasis is disrupted, coagulation is promoted, and in the absence of anticoagulation, a thrombus may form in the device, resulting in device failure or embolic stroke...
