Cardiac surgery at the University of Ottawa Heart Institute is dedicated to life-saving procedures and to advancing surgical techniques and treatment methods. Our surgeons specialize in reconstructing damaged portions of the heart and solving complex problems, often using minimally invasive procedures. Our surgeons have pioneered novel methods that are now used around the world, including minimally invasive multivessel coronary bypass surgery and key aspects of aortic valve repair.
We have one of the most successful and innovative heart surgery programs in Canada. We are an internationally recognized leader in less invasive bypass and valve surgery, repair of mitral, aortic and tricuspid heart valves, the quality of surgical outcomes, and patient satisfaction. Our heart transplant program has performed more than 700 transplants and serves patients from across the country. We pioneered innovative surgical methods, such as minimally invasive coronary artery bypass, and educated surgeons here and abroad in these new techniques.
We perform more than 1,900 open-heart procedures annually and conduct research into progressive clinical practices and scientific approaches to ensure the best possible outcomes for our patients. Cardiac surgery has a proud, founding legacy at the Heart Institute. Our physicians continue to set the standard in care, education, and research, nationally and internationally.
The Heart Institute is an international leader in cardiac surgery. We have among the lowest mortality rates and largest patient volumes throughout North America, particularly for high-risk patients. Our Cardiac Surgery program provides a model of surgical performance and expertise in which patient diagnosis, assessment, treatment, and follow-up involve a concerted team approach.
Through a small incision between the ribs, multiple healthy blood vessels are grafted onto arteries to bypass coronary blockages. Surgeons operate while the heart is beating, and they can address all vessels around the heart. The standard open-heart method involves stopping the heart, using a heart-lung machine, and incising the breastbone to open the chest. Only a few sites in North America perform this alternative procedure, particularly when multiple bypasses are needed, which requires specialized tools and training and was largely developed in Ottawa. We offer the procedure to be performed either in the “conventional” way or by using our newly acquired robot, donated in large part by the family of a grateful former patient.
We specialize in heart valve surgical techniques—for reconstruction of valves instead of replacement—including mitral and less commonly performed aortic valve repair. Our surgeons also perform aortic valve procedures by using minimally invasive surgical techniques. The comprehensive Valve Surgery Clinic follows patients after surgery to ensure thorough follow-up care over time.
For patients suffering from aortic stenosis (narrowing of the aortic valve) who are not good candidates for surgery, TAVI offers a minimally invasive option. Our medical team combines the exceptional skills of a surgeon and an interventional cardiologist in performing this catheter-based procedure. Well over a decade ago, our team at the UOHI was pioneeringly involved in the first 100 published cases worldwide of this now well-diffused procedure.
Similarly, a surgeon and an interventional cardiologist work closely together in bringing the latest to our patients in terms of percutaneous mitral valve and tricuspid valve interventions. This is currently known as the MitraClip Program.
The Heart Institute’s first transplant was performed in 1984. Today we conduct as many as 36 transplants here annually. Transplant patients are seen in the Heart Function Clinic when their hearts are no longer strong enough to pump adequate volumes of blood. The Heart Institute helps set the standard for transplant procedures and protocols across the country as a leading member of the Canadian Cardiac Transplant Group. In 2012, the Institute performed its 500th heart transplant, and we have since surpassed the benchmark of 700 such procedures.
Left ventricular assist devices (LVAD) temporarily replace the heart’s pumping action and are surgically implanted for patients with end-stage heart failure who are waiting for a heart transplant (known as “bridge to transplantation”). The device takes blood from the left side of the heart and pumps it back to the aorta, the major vessel in the body. An LVAD is used until a donor heart is available for transplantation or in patients who are expected to improve (known as “bridge to recovery”).
In this procedure, surgeons manoeuvre miniature tools through a keyhole-sized incision to destroy, or ablate, a targeted area of the heart. The ablation effectively short-circuits troublesome nerve endings responsible for atrial fibrillation, the most common form of arrhythmia.
In some patients, blood clots that travel to their lungs do not dissolve as they should and block the flow of blood. Blood pressure remains high, causing a persistent strain on the right side of the heart. The result is a condition known as chronic pulmonary embolism or chronic pulmonary hypertension. The Heart Institute is a designated Canadian centre for pulmonary thromboendarterectomy (PTE), a complex surgical procedure in which blood clots that block pulmonary arteries are removed.
Thoracic Aortic Repair
Like an inflated balloon, the wall of the aorta becomes thin and can tear (dissect) or rupture when it is stretched by an aneurysm. Aortic dissection or rupture requires immediate surgical repair. Patients with aortic disease are managed in the Aortic Clinic.
Surgeons and scientists at the Heart Institute combine their experience and skill to improve patient quality of life, ensure better outcomes, and maintain a progressive approach to cardiovascular medicine. From its inception, the Heart Institute has pioneered novel surgical procedures that give patients a chance to lead better lives. Internationally, we currently stand among the most productive divisions in the cardiac surgery landscape. Our Division is involved in nearly 80 scientific publications per year, and we regularly provide numerous expert lectures internationally. We lead many international clinical trials in coronary, minimally invasive, valve, and aortic surgery.

Our diverse skills, collaborative setting, and innovative procedures provide an excellent environment for training young physicians and researchers. Our educational activities address students at all levels.
Up to 15 medical students rotate annually through our cardiac surgery program, including elective students from the faculties of medicine in other provinces.
Cardiac surgery as accredited by the Royal College of Physicians and Surgeons of Canada for medical residents requires at least six years, following the completion of medical school.
The University of Ottawa offers clinical fellows one of the most advanced and diverse surgical training sites in Canada. To apply, both Canadian and International Medical Graduates must complete the Cardiac Surgery Fellowship Application form and submit documentation via the University's Faculty of Medicine, Postgraduate Medical Education website.

Postgraduate Peer-to-Peer Education
Our team has taught advanced surgical techniques at live symposia and in peer-to-peer fashion not only in Ottawa, but also at many other institutions around the world. Our surgeons have performed live surgeries watched by countless surgeons and team members, in Canada and in several countries abroad. Our division has also been entrusted with several international visiting awards given to established surgeons, to come spend several months at the UOHI and further their education and scope of practice.
Over the last decade, we have trained, through peer-to-peer observerships, well over 100 established, visiting heart surgeons and their teams, from institutions that include Stanford University, Columbia University, Harvard University, the University of Toronto, Leipzig German Heart Centre, Tohoku University, Georgetown University, Baylor University, Université Laval, McMaster University, and numerous others. Surgeons have come to learn MICS CABG, MICS valve, or advanced aortic valve procedures. Our peer-to-peer philosophy and collaborative programs have been an important component of furthering the diffusion of the surgical techniques that are performed and often were developed by our Cardiac Surgery Division, at the UOHI.
