Filter by:Pleural effusions continue to be a post-operative complication seen after Fontan operation. This study will examine the use inhaled nitric oxide (iNO) given for 54 hours after Fontan operation to improve fluid balance. The study hypothesis is that inhaled nitric oxide after Fontan operation will improve fluid balance, thus decreasing the incidence of pleural effusions and shortening hospital stay.
Randomized controlled trial of the use of glucocorticoids to improve the clinical course of neonates post-cardiopulmonary bypass (CPB).
To evaluate which of the two de-airing methods (CO2 insufflation vs. Lund de-airing technique) can shorten the left heart de-airing time and prevent or minimize cerebral air emboli during open surgery involving exposure of the left heart to the ambient air. To evaluate the cost effectiveness and possible side effects of CO2 de-airing technique compared to Lund de-airing technique.
Infants with congenital heart disease (CHD) requiring surgery frequently have brain injury seen on magnetic resonance imaging (MRI). This occurs in approximately 40% of these newborns, and even though these are full-term infants, the injury seen closely resembles the same form of brain injury that can be seen in premature babies. Much like premature newborns, infants with CHD also have long-term neurodevelopmental problems (in over 50%). The investigators do not know why infants with CHD get this specific form of brain injury. One risk factor is felt to be the inflammation that occurs in response to heart-lung bypass (cardiopulmonary bypass, or CPB), a necessary feature of open-heart surgery. Newborns have a stronger inflammatory reaction to CPB than older children or adults. The investigators do know from animal experiments and other human data that inflammation can be harmful to the developing brain. The investigators hypothesize that children with CHD requiring surgery as a newborn have brain injury due to toxicity from the inflammatory response. The investigators will test this by enrolling newborns undergoing heart surgery to measure markers of inflammation, measure brain injury by MRI, and then test their developmental outcome at 1 and 2 years of age. An association between inflammation and injury might impact what medicines are chosen to protect the brain in future studies, even in other populations such as preterm infants.
The purpose of this study was to investigate the effects of exercise training on exercise capacity, physical activity (PA), health-related quality of life (HRQoL), and the psychosocial factors affecting PA in sedentary congenital heart defect (CHD) children and healthy sedentary children. The degree of improvement after exercise training were compared between CHD children and healthy sedentary children.
Children (ages 0-12) that have heart surgery are often at a high risk of developing complications and have to be continuously monitored. Part of the routine care at UCLA includes using a monitor (continuous central venous oxygen saturation-ScvO2) to measure the amount of oxygen saturation in the tissues (indirectly) during surgery and in the intensive care unit. However, there is not much data on the use and effectiveness of this monitor in comparison to other monitors used for children. The purpose of this study is to further evaluate the effectiveness of the continuous central venous oxygen saturation (ScvO2) monitor in children and compare it with other monitors during a heart surgery. This is an observational study and the patients will not undergo any research specific procedures in the operating room (OR). The investigators will observe and record de-identified information, such as vital signs (heart rate, blood pressure, etc.), to evaluate the importance of the monitor. This study will also look at the demographics (age, gender, diagnosis, etc.) and treatments (type of surgery) received children undergoing heart surgery to improve quality of care. The investigators will also observe the same parameters in the ICU. The investigators hypothesized that low central venous saturations are associated with worse clinical outcomes.
The purpose of this study is to compare the incidence of silent and apparent cerebral embolism between conventional and minimal-invasive transfemoral aortic valve repair.
Adenosine has been proved to be an important mediator of myocardial protection induced by ischemic preconditioning. The hypothesis of this study is that adenosine preconditioning can provide additional myocardial protection in the setting of pediatric open heart surgery with cardioplegia and cardiopulmonary bypass.
The study research is to analyse brief episodes of limb ischemia applied to children the day before open heart surgery as protection from myocardial injury induced by extracorporeal circulation.
The purpose of this study is to determine whether ACE inhibitors alter the fibrinolytic, inflammatory, and hemodynamic response to cardiopulmonary bypass in infants and children with congenital heart disease.
