Heart Center Research
Our multidisciplinary team of physician-scientists conducts various research projects to advance the field, help promote patient care and better educate families.
Pediatric Heart Transplant Research
Physicians most recently have studied various topics related to pediatric heart transplant, including:
- Immunosuppression using Sirolimus
- Presence of donor-specific antibodies
- Multicenter study of ECMO in infants post transplant
- Exercise testing in heart transplant recipients
- Outcomes following ABO: incompatible heart transplants
The team also participates in the Pediatric Heart Transplant Study. Elfriede Pahl, MD, has been a lead investigator.
Dr. Pahl is the site principal investigator for the Pediatric Cardiomyopathy Registry (PCMR). Additionally, she is the site principal investigator for NIH-funded studies on genotyping of children with cardiomyopathy and biomarkers in cardiomyopathy. Lurie Children’s is one of 11 pediatric hospitals participating in this collaborative, government-funded study.
As the primary investigator for Transit, in partnership with co primary investigator Kathleen Grady, PhD, from Northwestern Memorial Hospital, the team is coordinating with nine partner hospitals in the NIH-funded study to provide educational intervention to adolescents with heart transplants to improve transition to an adult facility. Educational intervention helps the patients learn to manage their own care as they mature into adulthood.
Marfan Syndrome Research
- The Marfan Trial was a multi-center clinical trial that compared the effects of beta blocker therapy (atenolol) to those of angiotensin II receptor blocker therapy (losartan) in individuals with Marfan syndrome. The study found that losartan is as effective
as atenolol in leading to a significant decline in body size-indexed
aortic root dimension over time. The study also showed a stronger
response in younger age groups, suggesting that beginning therapy early
in the disease course may be provide a greater benefit. Read the press release to learn more.
- The Marfan Trial genetic ancillary study aims to assess how genetic and phenotypic variations affect response to treatment in patients with Marfan syndrome receiving atenolol and losartan.
- The Marfan Quality of Life Study aims to describe the quality of life for individuals with Marfan syndrome to normative data using standardized tools. The study is currently closed, but results are not yet available.
- The Circulating TGF-β levels in Marfan syndrome study aims to determine if circulating TGF-β levels correlate with specific treatment arms in the Marfan Trial (i.e., atenolol versus losartan). The study is currently closed, but results are not yet available.
- The Development of a Blood Test for Marfan Syndrome is a multicenter study which aims to identify differences in proteins that reflect genetic abnormalities in people with Marfan syndrome. The hope is to develop a non-genetic biomarker test to identify patients at high risk for aortic complications. Joseph Camarda, MD, and Elizabeth Cappella, APN, are the local investigators collaborating on this ongoing study.
Clinical and Translational Research
- Our cardiovascular-thoracic surgery team has participated in the Society of Thoracic Surgeons Congenital Heart Surgery national database since its inception in the mid-1990s. The national database contains de-identified, HIPAA-compliant patient data that helps our center benchmark its outcomes against that of other centers nationwide. Learn more about our volumes and outcomes.
- Lurie Children's Cardiac Imaging team is leading several research inititatives. Learn more.
- The multidisciplinary MR/CT program is leading research 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 cardiologist Joshua Robinson, MD, and radiologist Cythia Rigsby, MD, 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. Learn more about medical imaging research.
- Joshua Robinson, MD, Elizabeth Cappella, APN, and Bradley Marino, MD, are collaborating with Northwestern Memorial Hospital on the Bicuspid Aortic Valve Registry. The joint partnership between the Lurie Children’s and Bluhm Cardiovascular Institute’s Bicuspid Valve Programs has created a centralized database to collect clinical information about the physiologic and genetic mechanisms of BAV in order to improve long-term outcomes.
- Clinically silent genetic diseases may be responsible for as many as 25% of sudden unexplained deaths between 1 and 35 years of age. Given this high genetic incidence, a sudden unexpected death in a family member is a signal that other relatives may also be at risk for sudden death. Pediatric cardiac electrophysiologist R. Gregory Webster, MD, is engaged in research focusing on two issues that might prevent optimal evaluation of first-degree relatives of victims. First, we do not yet understand which clinical tests will lead to a diagnosis in the family. Second, no studies have evaluated how often genetic mutations are new mutations in the deceased child versus familial mutations present in the family. Dr. Webster’s research is a partnership between Lurie Children’s, medical examiners in Illinois and the Cardiovascular Genetics Center at Northwestern University. This collaboration provides a unique ability to identify clinical and genetic risk factors for sudden unexplained death in young persons and their family members.
Cardiac Critical Care Clinical Research
The Heart Center’s critical care clinical research includes:
- Steroid use and its effect on the stress response after open-heart surgery
- The optimal timing of birth in neonates with critical congenital heart disease
- Outcomes for patients with genetic syndromes who are supported with ECMO
