11 Clinical Trials for Various Conditions
This clinical trial is studying the use of different levels of oxygen exposure during and after cardiopulmonary bypass in eligible infants to learn about its safety during heart surgery. In addition to having the various doses of oxygen, participants will also have blood samples, ultrasounds of the head, and brain wave patterns monitored. The hypotheses of this trial are: * that there will be no difference with regards to adverse events between the infants in the normoxia group compared to the infants in the standard of care group * there will be a significant difference in the measured partial pressure of oxygen (PaO2) values between the two treatment groups. * the use of normoxia during cardiopulmonary bypass and in the immediate post-operative period will result in clinically significant decrease in oxidative stress as measured by thiobarbituric acid reactive substances (TBARS) after cardiac surgery
Infants with congenital heart disease have more frequent infections and exposures to antibiotics than healthy infants. It is unknown how congenital heart disease affects the development of bacterial colonization of the intestines. It is also unknown whether probiotics will change the bacteria in the intestine of infants with heart disease to become more like those of healthy infants without heart disease. This pilot trial is designed to address these two questions.
Anemia is a common disorder in infants with one working chamber of the heart that pumps blood. Anemia is when the level of healthy blood cells becomes too low. This may cause other health problems because red blood cells contain hemoglobin, which carries oxygen (needed for survival) to different parts of the body. This study will look at the role of iron in preventing anemia in infants with one pumping chamber. The importance of iron therapy will be examined. Hypothesis: Prophylactic use of iron in infants with single ventricle is effective in preventing anemia.
Adults with cyanotic congenital heart disease have elevated levels of plasma proatrial natruretic peptide (proANP) which most likely results in chronic dehydration, leading to reduced oxygen transport to tissues and shortness of breath with activity. The purpose of this study is to characterize adults with cyanotic congenital heart defects with respect to their body composition (water and fat-free mass) and resting metabolic rates. The study consists of several measures of how much body water, fat and lean tissue a subject has, and measures the number of calories the subject's body uses at rest. Adult subjects with cyanotic congenital heart disease will be recruited along with healthy noncyanotic control subjects matched for age, gender, and body weight.
Cyanotic congenital cardiac patients require higher hemoglobin concentrations (red blood cell levels) for optimal oxygen delivery to the body. Prophylactic erythropoietin (EPO) and iron can prevent and/or decrease the amount of blood transfusions needed in this population. We seek to investigate if EPO and iron make a clinically significant difference in the number of transfusions given to these patients and the morbidity associated with it.
Newborn babies with congenital heart disease often require surgery in the first month of life. The risks of brain damage from congenital heart disease and from the various corrective surgeries are high because of poor levels of oxygen reaching the brain. Topiramate is an anti-convulsant medication that protects brain cells from damage due to low amounts of oxygen in animal studies. The investigators hypothesize that giving topiramate to babies with congenital heart disease before and after surgery will decrease the amount of brain damage caused by the heart disease and/or the surgery to correct the heart disease.
All neonates with congenital heart disease undergoing stage one palliation (Norwood procedure, Damus-Kaye-Stansel procedure) at Texas Children's Hospital will be regularly monitored for B-type natriuretic peptide (BNP) and Troponin level before the surgical procedure, on arrival to the cardiac intensive care unit after their surgical procedure, every 6 hours during the first 24 hours of the post-operative period, followed by daily levels for the first week, and then weekly during patient's regular laboratory work up schedule. These cardiac biomarkers are linked to demographic, hemodynamic, respiratory, pharmacological data available via Sickbay.
This study is the extension of the CLARINET study \[NCT00396877 -EFC5314\] in neonates or infants with cyanotic congenital heart disease palliated with a systemic-to-pulmonary artery shunt. The primary objective was to assess the safety up to 18 months of age of the extended use of Clopidogrel 0.2 mg/kg/day in patients for whom the shunt was still in place at one year of age. The secondary objective was to assess the efficacy on the occurrence of shunt thrombosis requiring intervention or any death.
Contemporary management of cyanotic congenital heart disease includes three stages of surgery. Incidence of shunt thrombosis and death between the two first stages of palliation remains important. The primary objective of the study is to evaluate the efficacy of Clopidogrel 0.2 mg/kg/day for the reduction of all cause mortality and shunt related morbidity in neonates or infants with cyanotic congenital heart disease palliated with a systemic-to-pulmonary artery shunt (e.g. modified Blalock Taussig Shunt \[BTS\]). The secondary objective was to assess the safety of Clopidogrel in the study population.
The primary objective of this study is to determine the clinical benefits of percutaneous intervention to improve pulmonary blood flow on oxygen saturations, symptoms, exercise tolerance and hematocrit in patients with complex cyanotic congenital heart disease who are not candidates for surgical repair.
Heterotaxy syndrome is a heterogeneous disease that is the result of a failure of normal right-left lateralization of the abdominal and thoracic organs during development. The major clinical manifestations include intestinal malrotation, functional asplenia and complex cyanotic heart disease. Hypothesis: There exists a yet, un-recognized, racial distribution in heterotaxy syndrome.
