Abstract Objectives: To retrospectively review the outcome of stent placement in neonates with a vertical ductus, present a technique of ductal stenting via the axillary artery and compare it to ductal stening via the femoral venous access.
Design: Nineteen patients with duct-dependent pulmonary circulations through a vertical ductus arteriosus were treated with stent implantation. Those patients were retrospectively included in the study. In the first nine of these cases, stent delivery was done transvenously. In the latter ten cases, we favored the axillary artery access to the transvenous approach for stenting the vertical ductus arteriosus. Wire-target technique was… More >

Abstract Objective: Angiographically detectable Thebesian veins (ThVs) are a rare finding sometimes associated with coronary steal and myocardial ischemia in adults, but there are limited data regarding prominent ThVs in the setting of complex congenital heart disease (CHD). This study represents the largest series to date describing the presence and temporal changes of angiographically detectable ThVs in children with CHD.
Methods: This is a single center case series describing the clinical characteristics and coronary anatomy in children with CHD and angiographicall detectable ThVs. After identification of the index case, additional patients were identified in a prospective manner during… More >

Abstract Objective: Coarctation of the aorta (CoA) is a common condition. Adult patients with newly diagnosed CoA and patients with recurring or residual CoA require evaluation of the severity of aortic obstruction. Cardiac catheterization is considered the gold standard for the evaluation of hemodynamically significant CoA. The European Society of Cardiology (ESC) Guidelines for the management of grown-up congenital heart disease (GUCH) include noninvasive criteria for identifying significant CoA. Our aim was to investigate the ability of the Class I and Class IIa ESC recommendations to identify significant CoA at cardiac catheterization.
Design: Sixty-six adult patients with native… More >

Abstract Objectives: The primary aim of this study was to compare thermodilution (TD) cardiac index (TDCi) measured by injecting cold saline (C-TDCi) to saline at room temperature (R-TDCi). The secondary aim was to assess the change in body temperature with cold saline injections in children.
Design: This is a prospective, case control study.
Setting: Cardiac catheterization lab at Le Bonheur Children’s Hospital, Memphis, Tennessee.
Patients: Eighty-six children ≤18 years of age that underwent cardiac catheterization between April 2013 and April 2015, excluding patients with admixing lesions, on inotropic support and with ejection fraction < 30%.
Interventions: A TD catheter in the… More >

Abstract Background: The progression of hepatic disease in adult Fontan patients is not well understood. They reviewed the experience with serial cardiac MRIs (CMR) in adult Fontan patients to determine if hepatic anatomic markers of prolonged Fontan exposure were present and if clinical predictors of progressive hepatic congestion could be identified.
Methods and Results: A retrospective cohort study of all adult Fontan patients who had undergone at least two CMRs was performed. Hepatic dimensions, inferior vena cava (IVC) size, right hepatic vein (RHV) size and spleen diameter were determined from images acquired at the time of clinically guided… More >

Abstract Background: Antenatal diagnosis of congenital heart defects (CHD) can impact outcomes in neonates with severe CHD. Obstetric screening guidelines and the indications for fetal echocardiography (FE) have evolved in an attempt to improve the early prenatal detection of CHD. Analyzing yield for specific indications will help clinicians better stratify at-risk pregnancies.
Methods: Retrospective cohort study of all FE performed between 2000 and 2010 at a single tertiary care academic medical center in New York City. A total of 9878 FE met inclusion criteria for our study. In cases of multiple gestations (MG), each fetus was counted as… More >

Abstract The development of flax fiber reinforced polymer composites with improved properties has been increasingly studied by many researchers because of their sustainability. However, the effects of thermal residual stresses on the interfacial properties of flax composites have not been evaluated or very well understood. In this study, the thermal properties of flax, vinyl ester matrices and their composites were accessed by different techniques, including thermomechanical analyzer, dynamic mechanical analyzer, and X-ray diffraction combined with aluminum particles. The effects of thermal properties of flax fibers and vinyl ester resin systems on the mechanical properties of their More >

Abstract The Habanero pepper (Capsicum chinense) is intensively cultivated in the Yucatan peninsula, México. Because of adverse environmental conditions, it required seeding in germination trays, from which six-week-old seedlings were transplanted to the soil. Adequate nursing and fertilization programmes were made to improve health and vigour before seedlings transplanting. During seed germination, we investigated the effects of inoculation with four plant growth-promoting rhizobacteria (PGPR) on growth, nutrient uptake and gas exchange of 8-week-old Capsicum chinense plants. Inoculation was made with Pseudomonas sp. -P61-, Pseudomonas sp. -A46-, Bacillus pumillus -R44-, and Paenibacillus polymyxa-BSP1.1-. The BSP1.1 strain produced the highest increase in… More >

Abstract Seed inoculation with bacterial species has the potential to increase yield and agro-qualitative attributes of forage crops. This study determined the response of forage maize to three plant growth promoting rhizobacteria [PGPR1 (Azotobacter chroococcum), PGPR2 (Pseudomonas flourescens) and PGPR3 (Bacillus megaterium)] inoculated individually and in different combinations (PGPR1+2, PGPR1+3, PGPR2+3 and PGPR1+2+3). A non-inoculated treatment was kept as a control. We used a completely randomized block design with four replicates. The PGPR1+2+3 treatment showed an outstanding performance by improving yield attributes, green forage yield, dry matter biomass, crude protein and total ash. The same treatment gave the lowest More >

Abstract Soil compaction represents an important issue in the actual context of agricultural system sustainability. Research on the various developments of root systems under tillage has been explored for many crops, whether for the biomass area or the underground, but very little concerns Sunflower (Helianthus annuus L.). The objectives of the study were to understand the impact of soil tillage and of the induced mechanically compacted soil on: i) sunflower’s root system architecture, ii) biomass area iii) production. Two complementary experiments were realized in the south of France (France’s main sunflower production area). In both experiments, increased More >
