Active clinical trials for "Heart Defects, Congenital"

The objective of this randomized clinical trial is to test the effectiveness of a low-cost hybrid remotely monitored parent-mediated and clinic-based multidisciplinary early intervention (EI) for low-income infants with CHD in Brazil. The intervention protocols will be administered according to age modules, families will be monitored weekly. High risk infants also receive supplemental clinic-based interventions according to developmental needs. Controls will receive standard of care and access to early child development and nutrition practices information from the Brazilian Ministry of Health. All infants will be evaluated at within a 42-month follow-up research outpatient clinic, called NeuroCardio Baby at Santo Antonio Pediatric Hospital, of the Santa Casa de Misericordia Hospital Complex, and affiliated with The Cardiology Institute-University Foundation of Cardiology (IC-FUC), Porto Alegre, Brazil.

The aim of this study is to perform a pilot study investigating the first attempt intubation success rate differing between video laryngoscope nasotracheal intubation and direct laryngoscope nasotracheal intubation. The study population will consist of 60 neonates and infants with congenital heart disease less than 1 year of age who need nasotracheal intubation during general anesthesia for cardiac procedures. Standard nasotracheal intubation will be performed using either a video laryngoscope or direct laryngoscopy. Neonates and infants will be randomly assigned (1:1) to standard video laryngoscopy (with one of the following systems: Storz C-MAC Miller Video Laryngoscope, Karl Storz, Tuttlingen, Germany or Mc Grath Video Laryngoscope, Medtronic, Boulder,USA) or to direct laryngoscopy with one of the following blades: Miller or Macintosh (Heine, Hersching, Germany).

The purpose of the study is to assess the feasibility of cardiac resynchronization under electroanatomic guidance in the event of primary implantation failure due to catheterization failure or instability in the coronary sinus ostium

This is a Phase III randomized controlled trial of a passive ROM exercise program that will be performed in infants with HLHS and other single right ventricle anomalies following the Norwood procedure at PHN and Auxiliary Centers.

Background: A heart catheterization is a diagnostic heart procedure used to measure pressures and take pictures of the blood flow through the heart chambers. Magnetic resonance imaging (MRI) fluoroscopy shows continuous pictures of the heart chambers that doctors can watch while they work. Researchers want to test this procedure with catheterization tools routinely used in x-ray catheterization called guidewires. Guidewires will help move the heart catheter through the different heart chambers. Guidewires are usually considered unsafe during MRI because MRI can cause a guidewire to heat while inside the blood vessels and heart. Researchers are testing special low energy MRI settings that allow certain guidewires to be used during MRI catheterization without heating. Using these guidewires during MRI may help to decrease the amount of time you are in the MRI scanner, and the overall time the MRI catheterization procedure takes. Objectives: To test if certain MRI settings make it safe to use a guidewire during MRI fluoroscopy. Eligibility: Adults 18 and older whose doctors have recommended right heart catheterization. Design: Researchers will screen participants by reviewing their lab results and questionnaire answers. Participants may give 4 blood samples. Participants will be sedated. They will have a tube (catheter) placed in the groin, arm, or neck if they don t already have one. Patches on the skin will monitor heart rhythm. Special antennas, covered in pads, will be placed against the body. Participants will lie flat on a table that slides in and out of the MRI scanner as it makes pictures. Participants will get earplugs for the loud knocking noise. They can talk on an intercom. They will be inside the scanner for up to 2 hours. They can ask to stop at any time. During a heart catheterization, catheters will be inserted through the tubes already in place. The catheters are guided by MRI fluoroscopy into the chambers of the heart and vessels. The guidewire will help position the catheter.

This is a randomized, double-blind, placebo controlled, multicenter study to compare the efficacy and safety of L-citrulline versus placebo in patients undergoing surgery for congenital heart defects. Eligible patients undergoing repair of a large unrestrictive ventricular septal defect (VSD), a partial or complete atrioventricular septal defect (AVSD), or an ostium primum atrial septal defect (primum ASD) will be eligible for enrollment.

The Congenital Heart Disease Physical Activity Lifestyle Intervention Study (CHD-PALS) V.2 seeks to determine the efficacy of a lifestyle intervention program for adolescents and young adults (AYAs) with congenital heart disease (CHD). This trial was adapted from the original CHD-PAL trial to continue improving cardiovascular outcomes for transition-aged CHD survivors.

The objective of this project is to evaluate the capability of a specific mobile electrocardiogram monitoring of detecting arrhythmic events in children with history of palpitation and or syncope. We will compare this approach with the standard approach of clinical follow-up plus 24-hour Holter ECG monitoring in terms of acceptability and ability to identify significant arrhythmias.

The goal of this randomized controlled trial is to evaluate the effectiveness of video conferencing for the delivery of live-supervised, real-time cardiac rehabilitation (CR) exercise training to groups of adolescents with congenital heart disease (CHD) in their homes. Participants will be randomized to either the remote cardiac rehab (RCR) group or active control group. The RCR group will participate in live, group-based exercise training (3-5 participants per exercise session), in their homes 3 days per week for 45 minutes over 12-weeks. Exercise sessions will be led and supervised by a live health coach via telehealth video technology. The active control group will be provided informational handouts on health exercise for their cardiac diagnosis. The primary aim is to compare between group changes (0-12-weeks) in cardiorespiratory fitness (VO2peak). Secondary aims are to compare between group changes (0-12-weeks) in cardiac function (echocardiography), lean body mass, and physical frailty. Exploratory aims will compare between group changes (0-12-weeks) in physical function, quality of life, skeletal muscle function, and physical activity self-efficacy. Additionally, exploratory aims will explore the impact of demographic characteristics, program participation, program satisfaction, and daily physical activity on changes in cardiorespiratory fitness.

In this research study we want to learn more about abnormal heart rhythm after cardiac surgery in children. These abnormal heart rhythms, also called arrhythmias, may occur due to several reasons after cardiac surgery. They can be due to abnormal electrical pathway or an irritable area of the heart that stimulates abnormal impulses. Regardless of the cause, arrhythmias after cardiac surgery can be a problem, extending the hospital stay, requiring additional medications and even leading to cardiac arrest. Current practice is to monitor for arrhythmias after cardiac surgery, and to treat them if they occur. With this research, we want to investigate whether we can identify patients who will develop arrhythmia, and treat them before they occur.
