The aim of this study is to estimate the trend of right and left energetic parameters in left ventricular assist device (LVAD) pediatric patients. Echocardiographic data were retrospectively collected at the baseline, in the acute phase after and at the monthly follow-ups till the LVAD explantation to estimate left and right ventricular energetic parameters. A significant relationship between the left and right ventricular energetic parameter trends was found along all the study period. Left ventricular end-systolic pressure-volume relationship improved till the follow-up of 2 months and then progressively decreases...

Right ventricular failure (RVF) is a significant issue when considering left ventricular assist device (LVAD) implantation in pediatrics. The aim of this study was to evaluate the effects of LVAD on right ventricular (RV) function in children. We retrospectively reviewed clinical and echocardiographic data of children who underwent Berlin Heart EXCOR LVAD focusing on RV function before and after implantation (1, 3, and 6 month follow-up). An isolated LVAD was used in 27 patients. Median age was 11 months (interquartile range [IQR]: 5-24 months), with a median weight of 6...

BACKGROUND: The Infant Jarvik 2015 is an implantable axial-flow ventricular assist device (VAD) that has undergone the major evolutionary design modifications to improve hemocompatibility. This study was conducted in anticipation of data submission to the US Food and Drug Administration to obtain Investigational Device Exemption approval. METHODS: The VAD was implanted via a left thoracotomy in Barbado sheep (n = 10, 26 (19-34] kg). Anticoagulation was maintained with coumadin, with a target international normalized ratio of greater than the individual sheep's baseline values...

Mechanical circulatory support in the form of ventricular assist devices (VADs) in children has undergone rapid growth in the last decade. With expansion of device options available for larger children and adolescents, the field of outpatient VAD support has flourished, with many programs unprepared for the clinical, programmatic, and administrative responsibilities. From preimplantation VAD evaluation and patient education to postimplant VAD management, the VAD program, staffed with an interdisciplinary team, is essential to providing safe, effective, and sustainable care for a new technology in an exceedingly complex patient population...

BACKGROUND: As survival with pediatric left ventricular assist devices (LVADs) has improved, decisions regarding the optimal support strategy may depend more on quality of life and functional status (FS) rather than mortality alone. Limited data are available regarding the FS of children supported with LVADs. We sought to compare the FS of children supported with LVADs vs vasoactive infusions to inform decision making around support strategies. METHODS: Organ Procurement and Transplant Network data were used to identify all United States children aged between 1 and 21 years at heart transplant (HT) between 2006 and 2015 for dilated cardiomyopathy and supported with an LVAD or vasoactive infusions alone at HT...

Dilated cardiomyopathy in children still has a poor prognosis with high rates of mortality and cardiac transplantation (resp. around 20 and 25%). Awaiting transplantation or possible recovery, these pediatric patients are mechanically supported with extracorporeal membrane oxygenation or a paracorporeal ventricular assist device, both resulting in higher survival rates but also entailing considerable risks of infection, thrombosis, or bleeding. A new indication for an old technique, i.e., pulmonary artery banding, presents itself as an interesting alternative to mechanical circulatory support in selected infants and small children with dilated LV cardiomyopathy and preserved RV function...

The aim of this work is to develop and test a lumped parameter model of the cardiovascular system to simulate the simultaneous use of pulsatile (P) and continuous flow (C) ventricular assist devices (VADs) on the same patient. Echocardiographic and hemodynamic data of five pediatric patients undergoing VAD implantation were retrospectively collected and used to simulate the patients' baseline condition with the numerical model. Once the baseline hemodynamic was reproduced for each patient, the following assistance modalities were simulated: (a) CVAD assisting the right ventricle and PVAD assisting the left ventricle (RCF + LPF), (b) CVAD assisting the left ventricle and PVAD assisting the right ventricle (LCF + RPF)...

Pediatric heart failure represents an important cause of morbidity and mortality in childhood. Currently, there are well-established guidelines for the management of heart failure in the adult population, but an equivalent consensus in children is lacking. In the clinical setting, ensuring an accurate diagnosis and defining etiology is essential to optimal treatment. Diuretics and angiotensin-converting enzyme inhibition are the first-line therapies, whereas beta-blockers and devices for electric therapy are less used in children than in adults...

BACKGROUND AND PURPOSE: The pathogenesis of spontaneous pediatric vertebral artery dissections (VAD) is poorly understood but most often involves the V3 segment where C1 rotates on C2. We studied children with VAD with provocative digital catheter angiography and found an association between VAD and rotational compression. METHODS: Seven boys (12 months to 9 years; median 4 years) presented over 38 consecutive months with V3 VAD and underwent digital catheter angiography with provocative passive bilateral neck rotation...

Ventricular assist devices (VADs) have been placed as destination therapy in adults for over twenty years but have only recently been considered an option in a subset of pediatric patients. A 2016 report from the Pediatric Interagency Registry for Mechanical Circulatory Support (PediMACS) revealed only eight pediatric patients implanted as destination therapy. We report the case of an adolescent male with Becker Muscular Dystrophy (BMD) who underwent VAD placement in 2011 as bridge to candidacy. He subsequently decided to remain as destination therapy and so far has accrued over 2100 days on VAD support, the longest duration of pediatric VAD support reported in the literature to date...

Bleeding and thrombotic events remain a significant cause of morbidity in pediatric patients supported with ventricular assist devices (VADs). The objective of this study is to identify the association between markers of anticoagulation and bleeding and thrombosis events during Berlin Heart ExCor support. A retrospective, single-center analysis of 9 patients supported with the Berlin Heart ExCor was performed. Inflammatory and anticoagulation parameters including C-reactive protein, fibrinogen, partial thromboplastin time (PTT), and platelet count were measured at 48 and 24 h before and after bleeding or thrombosis events...

In Japan the 1st paracorporeal ventricular assist device (VAD) was implanted in 1980. Since then, more than 2,000 VADs were used. Small size continuous-flow VAD (CFVAD) was developed in 1990s, which dramatically improved safety and efficacy of long-term support. EVAHEART and DuraHeart, both of which were developed in Japan, were approved for health insurance coverage in 2011, followed by approval of HeartMate II in 2013 and Jarvik 2000 in 2014. Although these approvals were limited for bridge to transplantation, CFVADs gained rapid acceptance for treatment of end-stage heart failure...

Early primary graft failure after pediatric orthotopic heart transplantation (OHT) has a high mortality rate and can occur due to several causes including but not limited to prolonged graft ischemia time, suboptimal preimplant myocardial preservation, hyperacute rejection, and maladaptation of the graft to the host's hemodynamic status. Mechanical circulatory support with either extracorporeal membrane oxygenation (ECMO) or ventricular assist device has been used for the rescue of primary graft failure in pediatric patients after heart transplant...

Ventricular assist devices (VADs) are increasingly used to support children to heart transplant however, it is unclear if this trend is broadly applicable across the age/size spectrum. Children (<18years) listed for transplant were identified within in the United Network of Organ Sharing (UNOS) database from 1/2006-6/2014. Patients were stratified by era (Early: 2006-2010, Current: 2011-2014), size (<25 kg, 25-50 kg, > 50 kg) and device type. Of 3986 patients, 531 (13%) were supported by a VAD. The proportion of patients supported with a VAD has increased in the current era (16% vs...

A 13-year obese female with suspected viral myocarditis presented with acute decompensated heart failure. Due to her body habitus, she was a poor candidate for immediate heart transplantation. A peripherally inserted left ventricular assist device (LVAD) was implanted via the right axillary artery. Following device insertion the patient experienced rapid improvement in symptoms. The LVAD provided effective left ventricular unloading for 50 days, promoting myocardial recovery and maintaining excellent patient performance status...
