Filter by:We will test an ultrasound device that uses sound waves to detect the fetal heart beat, and use this device to tell the MRI scanner when to collect pictures of the fetal heart. This will help freeze motion of the fetal heart, to make MRI pictures sharper. This will be important for assessing human fetal heart disease, an active area of research at our institution.
The purpose of this retrospective study is to determine the incidence and severity of acute kidney injuries (AKI) after heart surgery on cardiopulmonary bypass (CPB) in the pediatric intensive care unit (PICU) in Lausanne, Switzerland.
Children with congenital heart diseases (CHD) often show reduced health related physical fitness as well as limitations in gross and fine motor skills/development. Intervention programs in childhood are still rare and often focus just on the improvement of cardiac outcomes or exercise capacity. Web-based interventions, as a useful alternative to training manuals or supervised training, are cost effective and allow a customization of training times. Primary purpose of this study is to improve health related physical fitness in children with congenital heart disease.
The study aims at investigating the role of cyanotic congenital heart disease (cCHD) on brain aging. The investigators assume that due to congenital and acquired cardiovascular abnormalities, cCHD patients could show radiologic (and clinical) signs of precocious brain aging and eventual cognitive decline.
The aim of the study is to assess the characteristics, incidence and predictors of load-independent right ventricle (RV) diastolic dysfunction in patients with congenital heart disease (CHD) and adverse RV loading conditions by acquiring pressure-volume loops and compare these results to a population of patients with exclusion of coronary artery disease and absence of any known disease affecting the RV.
This study aims to determine what are some of the clinical characteristics and associations of Fontan patients who are doing well, as well as how accurate cardiology providers are at predicting the likelihood of future adverse event in their Fontan patients.
Cardiac denervation is inherent to the arterial switch (ASO) technique for the repair of transposition of the great arteries (TGA) and the long term reinnervation process has not been studied. We sought to describe the reinnervation status of adult patients long after the ASO, to identify areas of myocardial perfusion/innervation mismatch and to assess the relation of innervation status and exercise capacity.
Our cluster randomized controlled trial of a novel clinical practice change will IMPACT the physical activity (PA) of children living with congenital heart defects (CHD) through our Innovative and pragmatic approach to systematically incorporate PA counselling within each clinic visit. Long-term, the focus is to prevent or treat the most common secondary morbidities of these patients (atherosclerosis, anxiety, depression) through enhanced PA. We have previously shown that home-based, PA interventions can increase daily PA and enhance PA motivation, motor skill and fitness when delivered via an intensive research intervention. Our objectives for this study are to Measure the feasibility and efficacy of PA counselling using clinical resources among paediatric CHD patients (daily PA, PA motivation, competence, quality of life) and on clinic systems (% patients counselled, clinic/kinesiology personnel support required, clinic visit time, # of PA questions). Our Patient-empowering, ready-to-use, self-explanatory "tool kit" of clinician PA resources and patient/family/clinician friendly searchable electronic PA database will be used to promote the Active lifestyles that are critically important to physical/mental health, peer socialization & childhood growth/development. 90% of children are not active enough for optimal health. We initially target children with CHD because they are less active than peers, and their most important secondary morbidities can be prevented or treated through PA. Our Collaborative approach with patients, their families and leaders in paediatric cardiac healthcare will optimize our "PA tool kit" and novel practice change for Translation to all paediatric CHD healthcare systems (primary, secondary, tertiary) through our pan-Canadian Cardiac Kids Quality of LIFFE Research and Knowledge Exchange Network, a collaborative of 10 patient/family support networks and 10 paediatric cardiac clinics in 6 provinces focused on Learning, Independence, Friends, Fitness & Emotional health (LIFFE).
The Just TRAC It! study (Transitioning Responsibly to Adult Care using smart phone technology) is a randomized controlled trial designed to evaluate the impact of using smart phone technology in combination with the nurse led transition intervention, versus the current standard of care (nurse led transition intervention including MyHealth Passport), on preparing adolescents with chronic cardiac disease to successfully transition from pediatric to adult cardiology care. "Just TRAC it!" is a mobile-health intervention designed to teach youth to manage their health using existing functions on their mobile devices. We propose to conduct a nurse-led intervention that encourages adolescents to use "Just TRAC it!" while addressing the healthcare transition needs of 16-18 year olds.
I. Study design: open/ blinded randomized, controlled study. II. Study setting and location: The study will be conducted in Abul Reesh Paediatric Hospital Faculty of Medicine /Cairo University from 2016-2018. III. Study population: This controlled open/blinded labelled randomized study is designed to include 40 children of both sexes scheduled for open-heart surgery for total correction of congenital heart diseases. IV. Eligibility Criteria: Inclusion criteria; 1. Paediatric patients of age group ranging from 6 months to 12 years . 2. Patients with complex congenital heart disease undergoing open heart surgery for total correction of the cardiac anomaly using cardiopulmonary bypass. Exclusion criteria; - Age less than 6 months or more than12 years. - Significant ventricular dysfunction (Ejection fraction < 40%). - Patients with pre-existing CNS disorders e.g.: seizures. - Patients with abnormal liver functions. - Pre-operative creatinine level >1.2 mg /dl. - Patients with history of diabetes mellitus. - Patients receiving NSAID for any reason. Study Protocol; The patients will be pre-medicated by atropine 0.01mg/kg, ketamine 0.03mg/kg and midazolam 0.02mg/kg IM, 30 minutes before induction of anesthesia. Standard ASA monitors, including electrocardiogram (ECG), pulse oximetry (Spo2), and non-invasive blood pressure cuff, and INVOS somatic oximeter probes will be placed on the renal area (on the back to the right or to the left from T10 to l2) will be placed on the patients before induction of anesthesia. Anesthetic technique will be standardized for all the patients in the form of inhalational induction using sevoflurane 6% in a mixture of oxygen and air (1:1) to be followed by placement of peripheral intravenous cannula. Intubation will be facilitated by pancuronium 0.01 mg/kg IV and ventilation will be controlled using pressure mode aiming to maintain PCO2 between (30-35 mmHg). Anesthesia will be maintained by mixture of 2% sevoflurane in 1:1 oxygen: air till time of CPB. A standard CPB technique will be used in all patients. Before aortic cannulation, patients will receive IV heparin 400 U.kg-1 aiming to produce ACT value > 400 sec. A membrane oxygenator (minimax plus ;Medtronics Inc.,Anaheim,CA) will be used during CPB. Priming solution in the form of isotonic saline solution supplemented with heparin added to fresh whole blood in appropriate amounts to achieve a hematocrit 20-25% during CPB will be used. Furosemide in a dose of 1mg .kg-1.min-1 will be given to all patients. Venting of left heart will be performed with a left atrial vent inserted through a small incision at the inter-atrial septum . Anesthesia during CPB will be given by Sevoflurane administrated via a vaporizer inserted into the oxygenator gas supply with a constant gas flow 3 liter.min-1. A non-pulsatile roller pump (model10.10.00;Stocket instruments ;Munich, Germany) will be used and the pump flow will be adjusted at 2.4 to 2.6 L/min /m2 during the normothermic period targeting mean arterial blood pressure between 40 and 60 mmHg. If the MAP will fall below 40 mmHg despite full perfusion pressure, a bolus dose of 0.01-0.1 ng /Kg phenylephrine will be given. If MAP increased above 60 mmHg, a continuous infusion of nitroglycerin at a dose of 1-2 µg.kg.min-1will be given. After application of aortic cross clamp and administration of cold cardioplegia solution (Saint Thomas cardioplegic solution, 20ml/Kg to be followed by doses of 10ml/Kg every 20 min.), time will be allowed to develop a stable level of perfusion pressure and moderate hypothermia (28°C-32°C). These variables will be kept constant for at least 10 minutes after initiation of full flow CPB and initiation of the study sequence. Thereafter, patients will be randomely allocated to DEX group (Group D n=20) receiving dexmedetomidine in a dose of 3 mcg/kg over 10 minutes to be followed by an infusion of 1 mcg/kg/hr to be continued until the first 6 postoperative hours.
