Aimee K. Armstrong, M.D., F.A.A.P., F.A.C.C. (firstname.lastname@example.org)
Aimee K. Armstrong, M.D., F.A.A.P., F.A.C.C. is a subspecialty board-certified pediatric cardiologist whose research focuses on measuring pulmonary endothelial function in the catheterization laboratory. She is also a co-investigator in a study of fetal cardiac interventions, including balloon dilation of the fetal aortic valve, in an attempt to prevent the development of hypoplastic left heart syndrome. In addition, Dr. Armstrong performs outcomes research in pediatric heart transplant patients and is studying the use of heparin as a therapy for protein-losing enteropathy.

John R. Charpie, M.D., Ph.D. (email@example.com)
John R. Charpie, M.D., Ph.D. is a subspecialty board certified pediatric cardiologist whose research focuses on myocardial ischemia-reperfusion injury in infants and children undergoing cardiac operations, and vascular endothelial dysfunction in children with congenital and acquired heart disease. As Medical Director of the pediatric cardiothoracic intensive care unit, Dr. Charpie is also interested in examining early and late outcomes following congenital heart disease surgery, and specific interventions aimed at improving morbidity and mortality including antioxidant therapies and therapeutic hypothermia. Dr. Charpie also serves as site Principal Investigator or Co-investigator for several multi-institutional, industry-sponsored drug trials in pediatric cardiology.

Robert J. Gajarski, M.D. (firstname.lastname@example.org)
Robert J. Gajarski, M.D. is a board-certified pediatric cardiologist whose primary research focus involves advancing the science of cardiac transplantation. This includes participation in new immunosuppression drug trials, long-term outcomes research and assessment of graft rejection and coronary vasculopathy using newer non-invasive imaging modalities coupled with gene-expression profiling. Currently, the transplant group is collaborating with a national consortium of pediatric transplant centers to investigate reasons and risk factors for adverse outcomes among patients with cardiomyopathy who undergo transplantation. The group is also evaluating quality of life (QOL) indicators in transplant patients and, based on that data, beginning to develop interventional strategies to facilitate the transition from pediatric to adult care while improving self-management skills for each patient.
Working in the cardiac ICU, Dr. Gajarski is also investigating neuro-hormonal dysfunction in cardiac surgery patients post-bypass and the potential benefits of tight glycemic control following cardiac surgery. In addition, as part of a core group of cardiac intensivists, he is collaborating with a larger institutional group (M-CHORD) to assess long-term outcomes and QOL after congenital surgical repairs as well as physiology-based and quality-improvement initiatives in the cardiac ICU.

Amnon Rosenthal, M.D. (email@example.com)
Amnon Rosenthal, M.D. is board certified in Pediatrics and Pediatric Cardiology and is Professor Emeritus of Pediatrics. His research focuses on therapy and natural history of patients with congenital heart disease, the long term outcome of cardiac surgery and the frequently associated hereditary syndromes and anomalies. In collaboration with other faculty members he evaluates the introduction and assessment of heparin therapy for Protein Losing Enteropathy, transtelephonic ECG monitoring for children with rhythm disturbance and potential changes and advancement of health care delivery.

Mark W. Russell, M.D.
Mark W. Russell, M.D. is a subspecialty board certified pediatric cardiologist whose research focuses on the growth and maturation of the heart during development and on the repair of heart muscle in response to injury. Dr. Russell directs an NIH, and Muscular Dystrophy Association, funded laboratory that is studying mechanisms of muscle fiber assembly, alignment and structural support, topics central to the causation of, and development of new therapies for, cardiomyopathy, muscular dystrophy and congestive heart failure. Recent work in his laboratory has identified and characterized a new family of proteins that are required for the assembly and organization of new muscle fibers. The long term goal of the project will be to use these novel proteins to help protect the heart and skeletal muscle from injury and promote healing of damaged tissue.
Dr. Russell was recently installed as the Aaron Stern Professor of Pediatric Cardiology. The resources of this professorship will be used to expand the laboratory’s research effort into the mechanisms that direct heart growth before a baby is born. The laboratory is characterizing the signaling pathways that direct heart growth with the goal of augmenting these signals in patients with hypoplastic left heart syndrome and other severe cardiac defects. His clinical studies are directed at understanding the genetic causes of heart disease, including both congenital heart defects and inherited forms of cardiomyopathy.

Mary E. van der Velde, M.D.
Dr. van der Velde is a subspecialty board-certified pediatric cardiologist whose research interests include fetal cardiology, echocardiography, ventricular function, and the natural history of congenital heart disease. As director of the fetal echocardiography program at Children's Hospital in Boston until 2003, she participated in the early trials of fetal cardiac intervention. Her current research interests include prenatal natural history of fetal cardiac disease, prediction of outcome using Doppler assessment of hemodynamics, and the effect of prenatal intervention on altering natural history.
Dr. van der Velde is the U-M cardiologist investigator for the multicenter Chronic Kidney Disease in Children Cohort Study (CKiD). This study, sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases (in collaboration with NINDS, NICHD, and NHLBI), is a prospective epidemiological study of children with chronic kidney disease in an effort to determine the risk factors for decline in kidney function, how this decline impacts neurocognitive function and behavior, the risk factors for cardiovascular disease, and growth failure and its associated morbidity. Cardiovascular evaluation includes echocardiographic assessment of cardiac function and hypertrophy, and aortic strain, distensibility and stiffness.
Dr. van der Velde is also the U-M echocardiographer for SVRII, the multicenter Single Ventricle Reconstruction Extension Study coordinated by the Pediatric Heart Network and funded by the NHLBI. She previously participated in a multicenter trial sponsored by NIAMSD assessing the efficacy of maternal dexamethasone treatment in preventing fetal congenital heart block.
