Abstract
Duchenne muscular dystrophy (DMD) is the most common form of childhood muscular dystrophy resulting in progressive muscle wasting and weakness. With advancements in respiratory care and the use of glucocorticoids, cardiomyopathy has surpassed respiratory compromise as the leading cause of morbidity and mortality in this patient population. As muscular dystrophy remains a relative contraindication to heart transplantation, end-stage heart failure management represents a major therapeutic challenge. Long-term left ventricular assist device (LVAD) therapy has emerged as a promising management strategy to improve the survival and quality of life in DMD cardiomyopathy. Preoperative planning, optimal patient selection, aggressive postoperative rehabilitation, and continued discussion of goals of care are critical considerations for the appropriate use of LVAD in DMD patients with cardiomyopathy.

Abstract
Background Ventricular assist devices (VADs) are increasingly being implanted in children, yet there is little literature to guide anesthetic management for these procedures. Aims To describe the pediatric population presenting for VAD implantation and the anesthetic management these patients receive. To compare (a) children under and over 12 months of age and (b) children with and without congenital heart disease. Methods Retrospective review of patients aged 0 to 17 years who underwent VAD implantation at a single center between 2014 and 2019. Results Seventy-seven VADs were implanted in 68 patients (46 left VADs, 24 biventricular VADs, 6 right VADs, and 1 univentricular VAD). One procedure was abandoned. Preoperatively, 20 (26%) patients were supported with extracorporeal membrane oxygenation and 57 (73%) patients were ventilated. Intraoperative donor blood products were required in 74 (95%) cases. Postimplantation inotropic support was required in 66 (85%) cases overall and 46 (100%) patients receiving a left VAD. Infants under 12 months were more likely to require preoperative extracorporeal membrane oxygenation (42% vs 19%), have femoral venous access (54% vs 28%), receive an intraoperative vasoconstrictor (42% vs 24%), and have delayed sternal closure (63 vs 22%). Mortality was higher in patients under 12 months (25% vs 19%) and in patients with congenital heart disease (25% vs 20%). Conclusions Children undergoing VAD implantation require high levels of preoperative organ support, high-dose intraoperative inotropic support, and high-volume blood transfusion. Children under 12 months and those with congenital heart disease are particularly challenging for anesthesiologists and have worse overall outcomes.

Abstract
Ventricular assist device (VAD) implantation is a widely used procedure in children with cardiac failure refractory to medical therapy as a long-term bridge to recovery or transplant. This strategy has proved to be of an enormous advantage in the cure of these children. The aim of this review is to evaluate the current strategies used for clinical monitoring of paediatric patients with a VAD, focusing on the management of several aspects such as anticoagulant and antiplatelet therapy, haemorrhagic and thrombotic complications, as well as the effects that VADs have on the exposure, effectiveness and the safety of drugs. The sources used for this research are MEDLINE, PubMed and Cochrane Library. The use of key words such as "paediatric ventricular assist device", "clinical management", "anticoagulant therapy" and "infections" retrieved 146 papers. With the application of the inclusion criteria, 42 articles have been selected, but following further analysis, only 21 were eligible. The post-implant process is still complicated due to the lack of guidelines regarding clinical management and for the frequent occurrence of adverse events including bleeding, infection and thromboembolic episodes. From these findings, we can highlight the importance of establishing a suitable antithrombotic therapy, as well as ensuring that the prevention and treatment of infection are paramount during the management of these patients. The clinical management of VAD paediatric children is complex and challenging. At the moment, there are no guidelines regarding strategies to adopt, but from the analysed surveys, it has been possible to highlight a relative coherence between adopted therapies in different centres worldwide.

Abstract
Durable ventricular assist devices (VADs) have significantly improved survival to transplantation among children with advanced stages of heart failure. The fundamental goals of VAD therapy include decreasing mortality, minimizing adverse events, and improving quality of life. As the pediatric VAD experience has evolved with reduced device related complications and improved survival, VAD therapy is being considered not only as a bridge to transplantation (BTT) but also as a bridge to decision (BTD) and as destination therapy (DT). Data regarding pediatric DT VAD are limited to anecdotal or case reports of children being supported for long periods with VADs and by default being classified as DT VAD. This article reviews current trends in the use of DT VAD and adverse events in children vs adults on VAD, and provides a framework for patient selection with the use of a multidisciplinary approach including palliative care. The general approach to determining DT VAD candidacy should include: 1) a reasonable success that the patient will survive the peri- and postoperative state; and 2) a high likelihood that the patient will be able to be discharged out of hospital and have adequate caregiver support. Patients with muscular dystrophy and failing Fontan physiology are examples of pediatric populations for whom DT VAD may be considered and which require unique considerations.
