Philosophy of Care

Dr. Choy feels the care of any child with heart disease should be a team approach.  An integral part of the team includes the parents, who should be well informed and part of the decision process on the management of their child.  The other part of the team includes his colleagues who are doctors, nurse specialists,nutritionist, and social worker.  Major decisions about the care of a patient should be made by the team.

Clinical Interests

Dr. Choy's clinical expertise includes general pediatric cardiology, heart disease associated with single ventricle physiology, and heart disease associated with Down's Syndrome,. He has previous research experience in cardiac embryology using the chick model.

Research/Academic Interests

Dr. Choy places a very high priority in the education of medical students and pediatric residents.  His teaching time is spent both in one-on-one teaching and group didactic sessions.
