NCT ID: NCT04667455 Active, not recruiting - Clinical trials for Cardiovascular Diseases

Improving Care for Children With Congenital Heart Disease.

Start date: February 17, 2020
Phase: N/A
Study type: Interventional

Establish a cardiovascular biomarker profile to help screening for congenital heart disease in infants and children as well as use non-invasive cardiac imaging in combination with such profiling to better predict the need for future cardiac interventions such as open heart surgery or cardiac catheter intervention selected types of with congenital heart disease.

NCT ID: NCT04291222 Active, not recruiting - Clinical trials for Patent Ductus Arteriosus

Feasibility, Efficacy and Safety of IBS ® for Implantaiton in the PDA in Duct-dependent Cyanotic CHD

Start date: December 11, 2018
Phase: N/A
Study type: Interventional

This is a pilot study on feasibility, efficacy and safety of IBS ® for implantation in the PDA in duct-dependent cyanotic CHD, and its objective is to investigate the feasibility, safety and efficacy of iron resorbable stent implantation in the PDA as initial palliation of cyanotic CHD with duct-dependent PBF.

NCT ID: NCT03782610 Active, not recruiting - Clinical trials for Bronchopulmonary Dysplasia

Early Prediction of Spontaneous Patent Ductus Arteriosus (PDA) Closure and PDA-Associated Outcomes

Start date: April 1, 2019
Phase:
Study type: Observational [Patient Registry]

Patent ductus arteriosus (PDA), very common in preterm infants, is the delayed closure of a fetal blood vessel that limits blood flow through the lungs. PDA is associated with mortality and harmful long term outcomes including chronic lung disease and neurodevelopmental delay. Although, treatments to close PDA likely benefit some infants, widespread routine treatment of all preterm infants with PDA may not improve important outcomes. Left untreated, most PDAs close spontaneously. Thus, PDA treatment is increasingly controversial and varies markedly between hospitals and individual providers. The relevant and still unanswered clinical question is not whether to treat all preterm infants with PDA, but whom to treat and when. Treatment detriments may outweigh benefits, since all forms of deliberate PDA closure have potential adverse effects, especially in infants destined for early, spontaneous PDA closure. Unfortunately, clinicians cannot currently predict in the 1st month which infants are at highest risk for persistent PDA, and which combination of clinical risk factors, echocardiographic (echo) measurements, and serum biomarkers may best predict PDA-associated harm. The American Academy of Pediatrics has acknowledged early identification of infants at high-risk from PDA as a key research goal for informing future PDA-treatment effectiveness trials. Our objective is to use a prospective cohort of untreated infants with PDA to predict spontaneous ductal closure timing and identify echo measurements and biomarkers that are present in the 1st postnatal month and associated with long-term impairment. Our central hypothesis is that these risk factors can be determined to inform appropriate clinical treatments when necessary. Clinical, serum and urine biomarkers (BNP, NTpBNP, NGAL, H-FABP), and echo variables sequentially collected during each of the first 4 postnatal weeks will be examined. In addition myocardial deformation imaging (MDI) and tissue Doppler imaging (TDI), innovative echo methods, will facilitate the quantitative evaluation of myocardial performance. Aim 1 will estimate the probability of spontaneous PDA closure and predict the timing of ductal closure using echo, biomarker, and clinical predictors. Aim 2 will specify which echo predictors and biomarkers are associated with mortality and severity of respiratory illness at 36-weeks PMA. Aim 3 will identify which echo predictors and biomarkers are associated with 22- to 26-month neurodevelopment. All models will be validated in a separate cohort. This project will significantly contribute to clinical outcomes and PDA management by reducing unnecessary and harmful overtreatment of infants with a high probability of early spontaneous PDA closure, and will permit the development of outcomes-focused trials to examine the effectiveness of PDA closure in those "high-risk" infants most likely to receive benefit.

NCT ID: NCT03675425 Active, not recruiting - Clinical trials for Patent Ductus Arteriosus After Premature Birth

The Effects of Phototherapy in Preterm Infants Pda

Start date: July 8, 2018
Phase: N/A
Study type: Interventional

The study was designed to assess whether chest shielding during phototherapy reduces the incidence of PDA, as assessed by serial echocardiographic examinations, in a population of extremely preterm infants born at lower 30 week gestation.

NCT ID: NCT03265782 Active, not recruiting - Clinical trials for Patent Ductus Arteriosus

Paracetamol Versus Ibuprofen for PDA Closure

Start date: June 2015
Phase: Phase 4
Study type: Interventional

Comparison between the safety and efficacy of oral paracetamol and oral ibuprofen in treatment of Patent Ductus Arteriosus (PDA) in premature infants

NCT ID: NCT02819414 Active, not recruiting - Clinical trials for Patent Ductus Arteriosus

Paracetamol Treatment of the Borderline Significant PDA

Start date: June 2016
Phase: Phase 2
Study type: Interventional

The therapeutic approach to the patent ductus arteriosus (PDA) in the premature neonate remains controversial. Currently it is generally accepted to treat only hemodynamically significant PDAs. The current investigation aims to study the effect of treatment on PDAs of borderline significance via a prospective, randomized controlled trial of paracetamol in this group.

NCT ID: NCT02739087 Active, not recruiting - Aortic Stenosis Clinical Trials

Radiation-Free Heart Catheterization Using MRI

Start date: March 2015
Phase: N/A
Study type: Interventional

Currently catheters used in heart catheterization procedures are guided throughout the heart chambers and blood vessels by pictures taken by x-rays. This technology exposes patients to radiation. With this study protocol the investigators will use MRI technology to take real-time pictures to navigate catheters throughout heart chambers. MRI uses electromagnetic energy; therefore, it does not expose participants to radiation energy.
