Co-Directors

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.

Kanishka Ratnayaka, M.D.

Dr. Ratnayaka’s research includes diagnostic MRI, MRI catheterization, X-ray fused with MRI (XFM,) MRI-guided intervention and MRI device innovation.

The Heart Institute Research Committee

Christopher Davis, M.D., Ph.D.

Dr. Davis’ research interests include studying exercise physiology of patients with congenital heart disease, athlete’s heart and diseases that cause sudden cardiac death in the young.

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.

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

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

Rakesh Singh, M.D., M.S.

Dr. Singh’s clinical and research interests include outcomes after heart transplantation, pediatric ventricular assist devices and heart failure management in congenital heart disease and cardiomyopathies. In addition, he is an active participant in the following multi-center registry research groups: Pediatric Heart Transplant Study (PHTS), Pediatric Interagency Registry for Mechanically Assisted Circulatory Support (pediMACS) and International Pediatric Heart Failure Registry (iPHFR).

Heather Sun, M.D.

Dr. Sun’s clinical and research interests include improved prenatal diagnosis and management of fetal congenital heart disease and non-traditional methods of functional cardiac assessment.
