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.

An angioplasty is a procedure that opens the narrowing in the arteries of your heart muscle to improve blood flow. It's not surgery, and you won't have any cuts in your chest or heart.
Instead, your doctor uses a tube (catheter) and inserts it into one of your arteries through your wrist or your groin. The catheter threads its way towards the heart and to the heart artery. Then a wire is passed along it, into your heart artery where the narrowing needs to be opened. A smaller catheter – with an inflatable balloon on the tip – is then passed along the wire to the blockage. The balloon is then inflated to open the artery and increase blood flow to the heart.
It's common for the doctor to also use what's called a coronary stent inside the artery. It's a device made of stainless steel or a metal alloy mesh that holds the artery open like a scaffold. When the balloon catheter is deflated and taken out, the stent stays in place permanently to keep the artery open. Over the next few months, the inner lining of the artery grows over the stent and helps it repair and heal.
If an additional type of procedure is required in your case, your physician will describe it to you in detail.
