Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

Cardiovascular Investigations Unit (CVIU)
An atrial septal defect is a hole in the wall that divides between the two upper chambers of the heart. These defects are present from birth. They usually vary in size from a penny to a loonie, and may damage the heart and lungs if left uncorrected.
An ASD Septal Occluders (Amplatzer Septal Occluder) is a double-sided disc that's used as a seal. It is separated by a waist which is sized to your defect. This device is made of surgical grade Dacron and metal alloys. These occluders can be inserted through a tube in the leg and implanted in the heart to close the defect.
