What it's like to work as a cardiac surgeon at UHN's Peter Munk Cardiac Centre (PMCC)?
There is no simple answer; every day presents new and exciting opportunities and challenges.
To help give people a glimpse, Dr. Maral Ouzounian let a camera follow her for a day.
A cardiac and aortic surgeon and surgeon scientist at PMCC, and an assistant professor of surgery at the University of Toronto, Dr. Ouzounian is also a married mother of two young children.
From home to office to operating room to clinic, Dr. Ouzounian takes viewers on a day in her life.
"I chose to go into medicine because I really felt compelled to do it," she says in the video. "Patients coming to you with an acute problem, without surgery they would do very poorly and they had a mechanical problem you could fix. I really loved that it was technical. I was hooked.
"This is what I was meant to do."
