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.

Cardiac Investigations Unit (CVIU)
We work to correct a defect in the heart that's often present even before birth. In an unborn baby's heart, there's a small blood vessel called the ductus arteriosus, located between the aorta and the pulmonary artery. This is a normal part of blood flow before birth. After a baby is born and begins to breathe, the ductus arteriosus usually closes on its own, but sometimes it stays open. This is called a Patent Ductus Arteriosus, or a PDA.
Your PDA will be closed during a procedure called a heart catheterization.
