Below is a list of all completed PHN studies. Learn about key findings and access study publications.
The Collaborative Learning study compared how well babies did after surgery at heart centers where babies were removed from the ventilator early versus at sites where babies were not taken off the ventilators early.
Learn More arrow_right_altThe purpose of this study was to figure out safe doses of a medicine called dexmedetomidine for babies having heart surgery.
Learn More arrow_right_altThe objectives of this study were to establish a Z-score database for common echo measurements based on a uniformly defined and racially diverse population of normal children from multiple centers over a wide geographic area and to collect electrocardiograms (ECG) from the same population for future establishment of ECG reference values.
Learn More arrow_right_altThis study was done to survey the health status of patients after Fontan surgery and to better understand how tests performed routinely to evaluate heart function relate to overall health status in patients after Fontan surgery.
Learn More arrow_right_altThis first follow-up to the Fontan study looked at how children and adolescents with single ventricle heart defects who participated in the Fontan Study were doing after their Fontan Surgery.
Learn More arrow_right_altThis is a second follow-up study of an existing cohort of children. In this study we would like to learn how these children and young adults, who are now between the ages of 15 and 25 years, have done since their enrollment in Fontan 1.
Learn More arrow_right_altIn the FUEL study, we investigated whether taking a medication called udenafil for 6 months helps improve heart function in children who had a Fontan operation.
Learn More arrow_right_altThis study was done to see if giving a medication called Enalapril (an ACE inhibitor) would improve a baby's growth and heart function in the first year of life.
Learn More arrow_right_altThis study evaluated pulse steroid therapy in kawasaki disease (KD). The purpose of this trial was to see if adding steroids (methylprednisone) to the standard treatment would improve coronary artery outcomes.
Learn More arrow_right_altThis study was done to compare two drugs (Atenolol and Losartan) to see if one is better than the other at slowing the speed of aortic enlargement. The study also compared the kinds of side effects that can occur when taking either of these medicines.
Learn More arrow_right_altThis was a study of ACE inhibition therapy in children with mitral regurgitation (MR) after Repair of an Atrioventricular Septal Defect (AVSD).
Learn More arrow_right_altThe purpose of this study was to see if a program of gentle physical exercise is safe and helps babies to grow after having surgery to repair their hearts.
Learn More arrow_right_altThe aim of this research was to study whether a scoring system called the Residual Lesion Score could predict how children with congenital heart disease do after cardiac surgery.
Learn More arrow_right_altThe purpose of this study was to find out whether the medicine called apixaban (commonly known as Eliquis®) is safe for children with heart disease, and to learn how much apixaban will be present in the blood after taking a certain dose.
Learn More arrow_right_altThe Single Ventricle Reconstruction (SVR) Trial was done to evaluate two commonly placed shunts to see which one would improve how patients do following the Norwood procedure.
Learn More arrow_right_altIn this first follow-up to the SVR Trial, we wanted to learn if these same children (2-6 years of age) do better with one of the two shunts (RV-to-PA or MBTS) in the years after surgery. We also explored how other medical and surgical factors affect children's health and how they develop.
Learn More arrow_right_altThis is the first Udenafil study in children or teens that have had Fontan surgery. This study aimed to learn about the possible benefit of Udenafil for children who have had a Fontan operation and to determine which dose of Udenafil is best.
Learn More arrow_right_altThis study was done to help us understand why there might be errors in measurements and the true change in heart function values over time.
