Brief Biography

Dr. Andrew Redington moved to Toronto from England in August, 2001 to take on the role of Head of Cardiology at The Hospital for Sick Children (SickKids).

Dr. Redington's research interests include ventricular function and cardiopulmonary physiology, mechano-electric interactions in congenital heart disease, and the pathophysiology of late postoperative functional decline. He has written more than 230 peer reviewed publications, more than 20 book chapters, and has co-edited six books. He is the editor of the congenital heart disease section of Current Medical Literature, and serves on the editorial boards of the Cardiology in the Young and Heart and Vessels.

Dr. Redington graduated from the University of London in 1981. He obtained his MRCP (UK) in Internal Medicine in 1984. In 1986 he was awarded a British Heart Foundation research scholarship and subsequently received his doctorate of medicine in 1988 (UK). He was appointed Consultant Paediatric Cardiologist at the Royal Brompton Hospital, London, in 1990 and was awarded a fellowship of the Royal College of Physicians in 1994 (UK). In 1998, he transferred his clinical and research teams to Great Ormond Street Hospital in London.

Clinical Care Activities

  • Cardiac catheterization
  • Echocardiography
  • In-patient and out-patient care

Research Interests

Long-standing interest in the pathophysiology of congenital heart disease, with emphasis on assessment of right ventricular function, cardiopulmonary interactions, and right left heart interactions.

  • Ventricular function and cardiovascular physiology
  • Ischemic preconditioning

Research Activities

Present research concentrates on analysis of myocardial performance using the abnormalities imposed by congenital heart disease and its surgery as natural models of chronic 'heart failure'. Current research interests are in two major areas: the non-invasive assessment of myocardial contractility using tissue Doppler techniques, and the use of a novel remote ischemic preconditioning protocol to protect the myocardium and other organs from the ischemic insult of cardiopulmonary bypass and ischemia re-perfusion injury.

Additional areas of interest include: right left heart interactions and their measurement using conductance catheter technologies, and the assessment of oxygen consumption and mechanisms of hibernation as they may apply to post-operative intensive care.

Future Research Interests

  • Development of non-invasive techniques for assessing myocardial performance.
  • The use of innate mechanisms of protection (eg. ischemic preconditioning) during cardiac surgery.
