Filter by:A single patient observational trial to evaluate growth velocity and clinical outcomes of an infant status post cardiac surgery who has failed to grow well and demonstrated intolerance to cow milk-based and elemental formulas and fortifiers on a 100% human milk diet including a human milk based human milk fortifier formulated for term infants fluid restricted due to surgically correctable congenital conditions.
The purpose of this study is to determine if NT-BNP levels obtained at time of admission for delivery are predictive of intrapartum or postpartum complications in patients with adult congenital heart disease.
Management of pregnancy and risk stratification in congenital heart disease (CHD) population might be challenging especially due to physiological haemodynamic modifications that inevitably occur during pregnancy. We aim to compare the accuracy of the main published scores including CARPREG II score in prediction of maternal complications during pregnancy in CHD patients.
"Xuefu-Zhuyu capsule" (XFZY) is made from a classic Fangji "Xuefu-Zhuyu Decoction" in an ancient Chinese medical book "Yi Lin Gai Cuo" by Chinese physician Wang Qingren, which is the most representative formula for the treatment of "Qizhi-Xueyu Zheng" (Qi Stagnation and Blood Stasis Syndrome). XFZY concludes 11 kinds of Chinese herbs: Danggui(Angelica sinensis), Honghua(Safflower Flower), Chishao(Paeoniae Radix Rubra), Shengdihuang(Radix Rehmanniae), Taoren(Peach Seed), Zhike(Fructus Aurantii), Jugeng(Platycodon grandiflorum), Chuanxiong(Rhizome of Chuanxiong), Chaihu(Radix Bupleuri), Chuanniuxi(Cyathula Officinalis),Gancao(liquorice).It is mainly used to treat "Qizhi-Xueyu Zheng", which includes the symptoms such as different types of pain, irritability or depression, insomnia, chest tightness, dark skin, lumps or masses in vitro or in vivo, petechiae on the tongue, and dark purple tongue. The purpose of the trial is to evaluate the efficacy and safety of XFZY in treating "Qizhi-Xueyu Zheng", and investigate the most suitable diseases of XFZY.
Neurodevelopmental impairment due to delayed brain development and brain injury is a fundamental problem in children with critical congenital heart disease (CCHD). Significant longterm motor-, cognitive-, and behavioral problems are the result of early postnatally and perioperatively induced brain injury. Allopurinol, a xanthine oxidase inhibitor, prevents the formation of toxic free oxygen radicals, thereby limiting hypoxia-reperfusion damage. Both animal and neonatal studies suggest that administration of allopurinol reduces hypoxic-ischemic brain injury, is cardioprotective, and safe. This study aims to evaluate the efficacy and safety of allopurinol administered early postnatally and perioperatively in children with a CCHD requiring cardiac surgery with cardiopulmonary bypass.
Acute kidney injury (AKI) following cardiac surgery for congenital heart defects (CHD) in children affects up to 60% of high risk-patients and is a major cause of both short- and long-term morbidity and mortality. Despite effort, to date, no successful therapeutic agent has gained widespread success in preventing this postoperative decline in renal function. Nitric oxide is an intricate regulator of acute inflammation and coagulation and is a potent vasodilator. The investigators hypothesize that nitric oxide, administered during cardiopulmonary bypass (CPB), may reduce the incidence of AKI.
The investigators will explore the feasibility and safety of two exercise interventions delivered both in the hospital and in participants' homes. Preteens and adolescents who have had repaired Tetralogy of Fallot (TOF), will be grouped by age and randomly assigned to either an aerobic or strength training exercise program supervised for 12 weeks. An exploratory aim of this study will be to examine changes in fitness level, muscle strength, muscle oxygen extraction and quality of life after the intervention, and compare these measures between groups. At the end of the study, participants and parents will be interviewed to assess their satisfaction and ideas for improvements in the program.
Severe pulmonary regurgitation is common in patients with Tetralogy of Fallot and results in progressive right ventricular dilatation and dysfunction. Pulmonary valve replacement is frequent in this population, and percutaneous procedures are increasing. Ventricular arrhythmias are a frequent late complication in patients with tetralogy of Fallot. The most common critical isthmus of ventricular tachycardias is between the pulmonary valve and the ventricular septal defect patch. While an electrophysiology study is sometimes performed in expert centers before surgical pulmonary valve replacement to guide a surgical ablation if needed, this approach is not recommended in current guidelines. An electrophysiology study should also be considered before percutaneous pulmonary valve replacement, as a part of the critical isthmus may be covered by the prosthetic pulmonary valve. Moreover, ablation after percutaneous pulmonary valve insertion exposes patients to the risks of traumatic valve or stent injury and infectious endocarditis. At present, reliable predictors to identify high-risk patients in whom an electrophysiology study should be performed before pulmonary valve replacement are lacking. The aim of this study is to assess prospectively the yield of systematic electrophysiology study and programmed ventricular stimulation before surgical and percutaneous pulmonary valve replacement in patients with tetralogy of Fallot.
The Strong People Strength Training study aims to assess whether a community-based progressive strength training program can improve risk factors for diabetes and heart disease in older rural adults.
This is a non-randomized, un-blinded study to evaluate Caption Health guidance software in patients in the medical surgery step-down unit. Patients will be scanned by a trained hospitalist and up to 4 standard views will be obtained per participant: PLAX, PSAX-PM, AP4 and SubC4. Observations will be made regarding human factors and performance of the device.
