Filter by:Patent ductus arteriosus (PDA) is a common problem in the neonatal intensive care unit and can be secondary to prematurity or congenital heart disease (CHD). PDA is the most common cardiovascular abnormality in preterm infants, and is seen in 55% of infants born at 28 weeks, and 1000 grams or less. In addition to producing heart failure and prolonged respiratory distress or ventilator dependence, PDA has been implicated in development of broncho-pulmonary dysplasia, interventricular hemorrhage, cerebral ischemia, and necrotizing enterocolitis (NEC). In an Israeli population study 5.6% of all very low birth weight infants (VLBW) were diagnosed with NEC, and 9.4% of VLBW infants with PDA were found to have NEC. In a retrospective analysis of neonates with CHD exposed to Prostaglandin E found that the odds of developing NEC increased in infants with single ventricle physiology, especially hypoplastic left heart syndrome. The proposed pathophysiological explanation of NEC and PDA is a result of "diastolic steal" where blood flows in reverse from the mesenteric arteries back into the aorta leading to compromised diastolic blood flow and intestinal hypo-perfusion. Prior studies have demonstrated that infants with a hemodynamically significant PDA have decreased diastolic flow velocity of the mesenteric and renal arteries when measured by Doppler ultrasound, and an attenuated intestinal blood flow response to feedings in the post prandial period compared to infants without PDA. Near Infrared Spectroscopy (NIRS) has also been used to assess regional oxygen saturations (rSO2) in tissues such as the brain, kidney and mesentery in premature infants with PDA. These studies demonstrated lower baseline oxygenation of these tissues in infants with hemodynamically significant PDA. These prior NIRS studies evaluated babies with a median gestational age at the time of study of 10 days or less. It is unknown if this alteration in saturations will persist in extubated neonates with PDA at 12 or more days of life on full enteral feedings. In the present study the investigators hypothesize that infants with a PDA, whether secondary to prematurity or ductal dependent CHD, will have decreased splanchnic and renal perfusion and rSO2 renal/splanchnic measurements will be decreased during times of increased metabolic demand such as enteral gavage feeding. To test this hypothesis the investigators have designed a prospective observational study utilizing NIRS to record regional saturations at baseline, during feedings, and after feedings for 48 hours.
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.
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.
Congenital heart disease (CHD) is the most common congenital malformations. The right ventricle in the sub-aortic position, or "systemic right ventricle" is one of these complex cardiac diseases. Several studies show that adults with CHD and especially systemic right ventricle have reduced exercise capacity. In addition, studies have shown that there is a correlation between alteration of aerobic physical capacity and alteration of right ventricular systolic function. Understanding and assessing the determinants of the physical capacity of patients with systemic right ventricles and evaluating their quality of life could allows us to improve their therapeutic management and also to expand patient indications to a program cardiac rehabilitation. This can benefit them on their exercise capacity, their tolerance to exercise and their quality of life. The aim is to study the correlation between the quality of life and the aerobic physical fitness of patients with a systemic right ventricle and to determine the clinical and paraclinical parameters that have an impact on the aerobic physical fitness of these patients. The quality of life of patients with a systemic right ventricle will be compared to that of the general population.
