Dr. Do has a special interest in outcomes research for patients in the CVICU in addition to looking at markers to predict liver dysfunction in single ventricle patients post Fontan palliation.

Kirsten Dummer, M.D.

Dr. Dummer’s interests include prenatal detection and management of fetal heart disease, identifying risk factors and predictors of outcome, and early diagnosis of fetal heart dysfunction in twin to twin transfusion syndrome.

Howaida El-Said, M.D., Ph.D.

Dr. El-Said’s research interest include 3-D angiography to facility catheterization procedures,  modifying stents to suit growing children, percutaneous valve development, innovative interventional techniques to avoid surgery, adult congenital Fontan patients and bioengineering of special wires to facilitate cath procedures.

Brian Fagan, M.D.

Dr. Fagan’s research includes investigation of Ebstein’s anomaly of the tricuspid valve.

Ian (Fraser) Golding, M.D.

Dr. Golding’s interests include prenatal detection, management and outcomes of fetal cardiac conditions, and the follow-up of infants and children with simple and complex congenital heart disease. He has organized several basic and advanced courses in fetal and pediatric echocardiography and pediatric cardiology. Dr. Golding also has an interest in medical informatics, having worked with vendors to develop various components of a pediatric cardiovascular information system and imaging reporting systems for both pediatric and fetal cardiology.

Paul Grossfeld, M.D.

Dr. Grossfeld’s research is focused on understanding the genetic basis of congenital heart disease. His primary interest is Jacobsen syndrome, a rare chromosomal disorder caused by the deletions in chromosome 11. Dr. Grossfeld has determined that loss of the ETS-1 gene causes hypoplastic left heart syndrome and other congenital heart defects in Jacobsen syndrome.

Aamisha Gupta, M.D.

Dr. Gupta’s research interests include optimization of cardiac care in the inpatient setting. She is involved in quality improvement and the development of systems to promote a team-based approach with family-centered care and improve hospital quality of care.

Jessica Haley, M.D.

Dr. Haley’s clinical and research interests include preventive cardiology with special focus on dyslipidemia and hypertension, as well as cardiopulmonary exercise stress testing.

Sanjeet Hegde, M.D., Ph.D.

Dr. Hegde’s research interests include in-vitro measurement of the safety of devices for interventional MRI, development of catheters and in-vitro testing of their suitability for interventional MRI, device implantation under XMR, catheter tracking under MRI, image guidance of cardiac interventions, 3-D printing, virtual reality and computational modeling of complex congenital heart disease.

Rachel McCandless, M.D.

Dr. McCandless has a special interest in fetal cardiology.

John W. Moore, M.D., M.P.H.

Dr. Moore’s major clinical and research focus is congenital and structural interventional cardiology.

Dana Mueller, M.D.

Dr. Mueller’s research interests include looking at outcome measures and identifying areas of potential intervention in the cardiac intensive care unit, with the goal of improving the future care of patients with critical cardiac disease.

Hari Narayan, M.D.

Dr. Narayan’s research is focused on the cardiotoxic effects of cancer therapies. He is interested in characterizing the natural history and risk factors for the development of cardiomyopathy after cancer therapy and determining the optimal diagnostic and management strategies for this disease.

James Perry, M.D.

Dr. Perry is interested in clinical and translational research projects on antiarrhythmic drugs, catheter ablation, adult congenital heart arrhythmias, computational modeling of congenital heart disease, innovative device designs, bioengineering and electrophysiology, cardiac genomics and channelopathies. 

Beth Printz, M.D., Ph.D.

Dr. Printz specializes in using echocardiography and cardiac MRI to better understand congenital heart disease in children and adults.
