The hypothesis of this study is that participation in a formal cardiopulmonary rehabilitation program improves aerobic exercise capacity and quality of life over the medium term for patients with congenital heart disease with reduced exercise capacity. To test this hypothesis, subjects will be randomized to either receive a 12-week cardiopulmonary rehabilitation program or standard of care, with interval testing of aerobic capacity and other physiologic markers improved fitness, as well as assessment of quality of life.
The purpose of this study is to understand the causes of growth failure and to define biochemical markers of nutritional failure in patients with single ventricle Congenital Heart Disease (CHD).
Infants with congenital heart disease have more frequent infections and exposures to antibiotics than healthy infants. The investigators hypothesized that synbiotics may reduce the rate of sepsis and necrotizing enterocolitis in infants with CHD
Healthy Lifestyles for Children with Complex Heart Problems is a planning and resource development project. The goal of the project is to develop an implementation plan that would enable children with complex heart problems to lead healthy, active lives within their own community. The primary goal of the project is to promote physical activity, because the physical and mental health benefits of activity are very important for these children. Children with complex heart problems have a higher risk for obesity, diabetes, acquired heart disease and mental health problems than their healthy peers. The physical health benefits of physical activity are well known, but physical activity is also key for children's mental health. Physical activity enables children to socialize with peers and create bonds and friendships. Physical activity participation also directly elevates mood through the release of brain chemicals. Children with complex heart problems are also known to experience fear and anxiety related to physical activity. This project will also develop strategies to promote healthy eating and the prevention of physical activity-related injuries to these children and their families. Children with complex heart problems are at higher risk of overweight and obesity and face unique injury risks related to pacemakers or their medications. Extensive consultations with families and caregivers have identified needed supports for physical activity lifestyles, mental health, healthy eating and injury prevention for these children. The goal of the interviews was to understand the positive and negative influences on physical activity and healthy lifestyles for these children. Analyses of the interview content was used to develop a detailed, step-by-step implementation plan to provide the supports necessary for children with complex heart problems to lead active, healthy lives in their own community, with their family and friends. The implementation plan specifies changes to family education and counselling resources, clinical care routines, and communication among professionals and families. The clinical trial will evaluate the impact of implementing the family supports and changes to practice previously developed. Surveys will be completed by families attending the cardiac clinic before and after the changes to practice and additional resources are made available. Interviews will be utilized to gather additional feedback from professionals and families that receive counselling utilizing the supplementary materials.
The remarkable improvement in survival of children with congenital disease has led to a continuously growing number of adults with congenital heart disease in the developed world. Many of these patients had had cardiac surgery at early age, the may live for many years with pressure overload, volume overload, systolic or diastolic dysfunction, cyanosis or any combination of the above. These past and ongoing cardiac insults often result in significant cardiac remodeling. A biomarker for fibrosis and remodeling may have enormous clinical and prognostic value for these patients. Serum biomarkers are now integrated in many fields in medicine. In cardiology, a number of biomarkers are used. In the last decade, our group has focused on the natriuretic peptides as markers for heart disease in infants and children. This resulted in many studies and more than 25 publications in the medical literature. We believe that the newly discovered cardiac marker, ST2, will emerge as an important addition to cardiac evaluation in the coming years.The aim of this study is to measure ST2 levels in patients with congenital right heart disease and correlate ST2 levels to clinical status, imaging and prognosis.
Previous studies have examined the usefulness of pulse oximetry or oxygen saturation to screen for left-sided cardiac lesions. These studies have shown that the occurrence of critical congenital cardiac malformations among asymptomatic newborns is high; the technique of pulse oximetry is reliable for detection of ductal dependant left-sided lesions, simple to operate(requires little time and can be done in the newborn nursery) and is cost effective; there is effective follow-up test (heart ultrasound) and available interventions have an effect on outcome for diagnosed newborns. The importance of this research project is to examine the overall helpfulness of measuring oximetry in newborn infants using somatic oximetry, as well ast to prepare for a population based study in the state of Florida.
This project will evaluate fluid balance and oedema formation in children with the same congenital heart disease (Atrial Septal Defect) who will either go through heart surgery with the use of Cardio Pulmonary Bypass and hypothermia or through interventional catheterization. The investigators will measure interstitial colloid osmotic pressure, distribution of proteins and cytokines. The study hypothesis is that "Oedema developed during heart surgery is caused by reduced colloid osmotic pressure gradient through the capillary membrane".
The purpose of this study is to evaluate the impact of implementing a universal pulse oximeter screening as a way to detect critical congenital heart disease in otherwise well-appearing newborns.
In 2012, infants having surgery for congenital heart disease have a high survival. The investigators are now focused on improving how sick these infants become after surgery (short term outcomes) and their later neurodevelopment (long term outcomes). During heart surgery, cardiopulmonary bypass (CPB; the heart-lung machine) takes over heart function while the surgeon repairs the heart disease. During this surgery there are periods of time when the amount of blood going to the heart and brain is lower than usual, called "ischemia". Once the surgery is finished the blood going to the heart and brain is increased to normal again, called "reperfusion". This ischemia-reperfusion can cause injury to the heart, brain, and other organs, affecting the short and long term outcomes in these infants. Adult studies have shown that a short time of ischemia to the legs for 5-10 minutes [the legs are not damaged by a short time of ischemia, unlike the heart or brain], before severe ischemia to another distant vulnerable vital organ [like the heart or brain], can protect this other vital organ from ischemia-reperfusion injury. This is called "remote ischemic preconditioning" (RIPC). Our objective is to test whether RIPC before heart surgery can improve the recovery of the heart and brain after heart surgery in newborn babies with congenital heart disease. The investigators will test whether RIPC will result in lower peak lactate and troponin levels on the day after heart surgery. Lactate levels are a marker for how much the different tissues of the body suffer from ischemia-reperfusion injury. Troponin is released from damaged heart during ischemia-reperfusion. In our trial infants will be randomized to RIPC or control. This means each baby has an equal chance of being in one group or the other. The intervention group will have RIPC before surgery; the "control group" will not. The investigators hope this trial will lead to a larger study to test if RIPC results in fewer days on a breathing machine after surgery, lower mortality, and higher scores on neurodevelopmental tests at 2 years of age.
