Specialties & ConditionsHeart Center Research
Our multidisciplinary team of physician-scientists conducts various research projects to advance the field, help promote patient care and better educate families in the following areas:
For many patients, the transition from pediatric to adult care can be confusing and overwhelming. Lurie Children’s Heart Center and the Bluhm Cardiovascular Institute at Northwestern Medicine have partnered to launch a first-of-its-kind program to help guide adolescents during the transition years. Transition refers to all of the planning, preparation and skill building that leads up to and surrounds the actual transfer of care, including choosing a new physician, transferring medical records, communicating treatment histories and navigating insurance coverage. The Cardiovascular Bridge programs are designed as a partnership between the patient, family, pediatric and adult cardiac providers to successfully bridge the medical needs of young patients with heart disease.
The first Cardiovascular Bridge Program has successfully launched for patients 16-26 years old with bicuspid aortic valve disease and aortopathy. Additional programs will be developed in coming years, expanding services to cardiomyopathy, adult congenital heart disease, transplant/extracorporeal support and preventive cardiovascular medicine. A fundamental aspect of the program is the specialty clinics designed to bring pediatric and adult cardiologists, nurses and other health care professionals together in a single setting, allowing young patients to start building relationships with the adult healthcare team they will continue to see in the future.
The main goals of the program are to:
Another significant aspect of the programs is to understand and optimize clinical outcomes for these high-risk cardiac populations through research. Lurie Children's Heart Center Research Core and the Bluhm Clinical Trials Unit have joined resources to coordinate research efforts across a patient’s lifespan from childhood, through adolescence and young adulthood, into adulthood. These research endeavors will help guide the best courses of care for a patient and give physician-scientists opportunities to better understand the natural history and mechanisms of heart disease.

The Heart Center’s critical care clinical research includes:
“Pediatric Heart Transplant Study (PHTS)” – Dr. Elfriede Pahl
The Pediatric Heart Transplant Study (PHTS) is a multi-center event driven study that was initiated by the University of Alabama at Birmingham on January 1, 1993 with the primary purpose being to examine the risk factors and outcome events following listing of a patient for a pediatric cardiac transplantation. The goal is to advance our state of knowledge and to disseminate this information via presentations at national meetings and by generating manuscripts for publication in peer-reviewed journals. By utilizing 17 different standardized questionnaires, outcomes data is collected at 52 transplant centers across the country for the purpose of determining risk factors and combining experience to improve the outcomes of heart transplantation. This dataset will also allow hospitals, including Lurie Children’s, to monitor performance on quality metrics surrounding heart transplantation and it can also serve as the core for the quality-improvement within the Heart Center for these patients.
“Quantitative Detection of Circulating Donor-Specific DNA in Heart Transplant Recipients” – Dr. Elfriede Pahl
Early detection of rejection is a major focus of organ transplant care. Detection of donor DNA after transplantation has been proposed as a means of detecting acute rejection in for heart transplant patients. In a pilot study, and in the on-going multi-center study, a proprietary approach has been applied to quantifying donor specific cell free DNA present in transplant recipient’s plasma, with high temporal resolution surrounding the time of transplant surgery as well as during episodes of rejection, in contrast to baseline levels from blood obtained at time of routine surveillance biopsies. The purpose of this study is to evaluate and continue to develop a non-invasive method of detection of transplant rejection by isolating donor specific DNA in plasma of organ transplant patients.
The multidisciplinary MR/CT program is researching ways to reduce MR imaging exam time and minimize anesthesia or sedation used during imaging exams. In the multi-year NIH/NHLBI funded study, Functional Cardiovascular 4D MRI in Congenital Heart Disease, Lurie Children's cardiologists and radiologists are collaborating with Northwestern bioengineers to develop a comprehensive 20-minute 4D MR exam that might replace the standard 60-90 minute MRI protocol. In addition to studying how the new technique may reduce exposure to anesthesia, the team is investigating how 4D visualization of complex blood flow dynamics may predict progression of cardiovascular disease. The visualization is shown below.
“Perinatal Cardiac Database” – Dr. Nina Gotteiner
The goal of this study is to develop a database of pre- and post-natal cardiac evaluations to learn more about fetal echocardiograms and fetal abnormality diagnosis. The data collected from the fetal echocardiogram will be used by Lurie Children’s cardiology physicians to ensure that the fetal diagnoses are accurate when compared to babies’ echocardiogram heart diagnosis after birth. The database will help physicians determine areas for improvement in care and diagnosis for mothers and their children born with different congenital heart diseases.
"CASCADE – FH" – Dr. Irwin Benuck
The Preventive Cardiology Program at Lurie Children’s is very pleased to have joined a nationwide study based at Duke University, the CASCADE Familial Hypercholesterolemia Registry. To date, we have enrolled over 58 FH patients.
Familial Hypercholesterolemia (FH) is one of the most common life-threatening family disorders. Individuals with FH remain vastly under-diagnosed and under-treated and are at an increased risk for heart disease and heart attacks at a young age. However, FH is manageable with the right care.
The FH Foundation is a patient-centered nonprofit organization dedicated to education, advocacy, and research of Familial Hypercholesterolemia. The FH Foundation has launched a national FH patient registry, the CASCADE FH Registry. This study is designed to collect comprehensive data on individuals with confirmed or suspected FH on a longitudinal basis. The CASCADE FH Registry will serve as a key instrument to support health service planning, increase knowledge on the disorder and pool data for epidemiological, clinical and outcomes research, as well as for surveillance of therapy effectiveness.
Lurie Children’s Hospital participates in the pediatric portion of the INTERMACs registry called Pedimacs. This registry gathers clinical and laboratory information on patients that receive ventricular-assist devices/mechanical circulatory support devices for end-stage heart failure. We are one of 167 active sites and 20,917 subjects enrolled study-wide. The registry and analyze clinical and laboratory data from patients who are receiving MCSDs for end-stage heart failure as well as their outcomes following implantation of legally utilized MCSDs. These results are expected to facilitate clinical evaluation and patient management while aiding better device development.'
“Improving Pediatric and Adult Congenital Treatment (IMPACT) Registry”
Improvements in medicine and new surgical procedures over the last 30 years have resulted in an increasing number of pediatric congenital heart disease patients surviving into adulthood. It is estimated that 50% of pediatric patients diagnosed with congenital heart disease undergo corrective treatment in their first year of life. Results of surgical procedures are tracked in registries and have shown valuable trends in delivery of care. There are no such catheterization registries and, as a result, the outcomes and variability of these has not been monitored. This study aims to collect data on children and adults with congenital heart disease (CHD) who are undergoing a cardiac catheterization. The collection and analysis of the data collected will be used to learn more and improve treatment of CHD.
“Pediatric Cardiac Critical Care Consortium (PC4)”
The Pediatric Cardiac Critical Care Consortium (PC4) aims to improve the quality of care for patients with critical pediatric and congenital cardiovascular disease in North America and abroad. Formed in 2009 with National Institutes of Health funding, PC4 is a unique collaborative of leaders in pediatric cardiac critical care, cardiac surgery, and cardiology representing a diverse group of centers caring for these vulnerable patients. The core pillars of collaborative quality improvement serve as the foundation for PC4: purposeful collection of specific clinical data on outcomes and practice; timely performance feedback to clinicians, and continuous improvement based on empirical analysis and collaborative learning. PC4 will be an international leader in the effort to improve care to critically ill patients with pediatric and congenital heart disease. Dr. Costello serves on the Executive Committee of PC4.
