Discharging children on ventricular assist device (VAD) support offers advantages for quality of life. We sought to describe discharge and readmission frequency in children on VAD support. All VAD-implanted patients aged 10-21 years at Advanced Cardiac Therapies Improving Outcomes Network (ACTION) centers were identified from the Pediatric Health Information System database (2009-2018). ⋯ Discharge of children on VAD support has increased over time, although variability exists across centers. Readmissions are common with diverse indications; however, the risk of mortality is low. Further interventions, including collaboration in ACTION, are critical to increasing discharges and optimizing outpatient management.

Venovenous extracorporeal membrane oxygenation (VV ECMO) can successfully support patients with refractory respiratory failure and is widely accepted as a bridge to recovery or bridge to transplantation. However, some problems hinder success. Recirculation, an innate complication of VV ECMO, hamper efficient oxygenation. ⋯ Compared to VV ECMO, it has advantages of hemodynamic support, elimination of recirculation, and facilitation of rehabilitation. In the present case, we overcame recirculation and impending RV failure by applying OxyRVAD to patient who was initially managed with VV ECMO. He underwent lung transplantation after about 6 months of OxyRVAD support with active rehabilitation, the longest maintenance period ever known.

Severe cases of coronavirus disease 2019 (COVID-19) cannot be adequately managed with mechanical ventilation alone. The role and outcome of extracorporeal membrane oxygenation (ECMO) in the management of COVID-19 is currently unclear. Eight COVID-19 patients have received ECMO support in Shanghai with seven with venovenous (VV) ECMO support and one veno arterial (VA) ECMO during cardiopulmonary resuscitation. ⋯ Except the one emergent VA ECMO during cardiopulmonary resuscitation, other patients were on ECMO support for between 18 and 47 days. In conclusion, ensuring effective, timely, and safe ECMO support in COVID-19 is key to improving clinical outcomes. Extracorporeal membrane oxygenation support might be an integral part of the critical care provided for COVID-19 patients in centers with advanced ECMO expertise.

The purpose of this study was to evaluate survival to hospital discharge for patients on venovenous extracorporeal membrane oxygenation (VV ECMO) when stratified by age. We performed a retrospective study at single, academic, tertiary care center intensive care unit for VV ECMO. All patients, older than 17 years of age, on VV ECMO admitted to a specialized intensive care unit for the management of VV ECMO between August 2014 and May 2018 were included in the study. ⋯ Patients 65 years of age and older treated with VV ECMO support for respiratory failure have low rates of survival to discharge. We have shown that age is an independent predictor of survival to discharge and beginning at age 45 years, in-hospital mortality increases incrementally. Moving forward we believe criteria and scoring systems for VV ECMO should include age as a variable.

Hemorrhagic and thrombotic complications are a significant source of morbidity and mortality for pediatric patients on extracorporeal membrane oxygenation (ECMO). Optimal anticoagulation therapies and monitoring strategies remain unknown. In 2013, our institution changed the anticoagulation monitoring protocol from activated clotting time (ACT) to antifactor Xa (anti-Xa) levels. ⋯ Secondary analysis showed no difference in transfusion requirements for red blood cells (ml/kg; p = 0.32) or platelets (ml/kg; p = 0.32). There was no difference in average heparin infusion rates (unit/kg/hr) per cannulation (p = 0.17) between the groups. Management of anticoagulation based on anti-Xa levels appears to be as effective as management based on ACT results.
