Dr.Maral Ouzounian received her MD from McGill University and did her residency in the division of cardiac surgery at Dalhousie University. Maral did a fellowship at the Texas Heart Institute and her PhD in the laboratory of our own Dr. Peter Liu, while working on gene expression in diabetes and hypertension-induced diastolic dysfunction.
Maral is appointed as a Surgeon Scientist and Assistant Professor in the Division of Cardiac Surgery, University of Toronto. Her area of clinical focus will be catheterbased and open surgical repair of thoraco-abdominal aneurysms.

Better understanding of disease could be a blood bank away
Kimberly has familial thoracic aortic aneurysm and dissection, a genetic mutation that runs in her mother’s side of the family. Because the operation involved removing part of the aorta that was weakened by her genetic disease, her cardiac surgeon, Maral Ouzounian, was able to encourage Kimberly to donate the tissue to the Peter Munk Cardiac Centre Cardiovascular Biobank.
The first signs of a coming health care crisis
His situation is far from unique. The hiring landscape for today’s new heart surgeons is dismal, with one in five failing to find full-time work. It’s a problem that may soon affect the public, as the current employment situation discourages today’s medical students from joining the profession. “It seems paradoxical but a lack of jobs for new surgeons today may lead to a shortage of heart surgeons in the future,” says Maral Ouzounian, a cardiac surgery resident at Dalhousie University and lead author of one of two groundbreaking papers due to be published this week in The Annals of Thoracic Surgery. Until 2006, Canadian cardiac surgery residency programs—which require six years of training after medical school, usually followed by fellowships—were full. In 2009, 55 per cent of spots stayed empty. If that continues, Canada’s cardiac surgical workforce could be cut in half in 20 years.
Transcatheter aortic valve implantation (TAVI) is an established treatment option for patients with aortic valve stenosis and high surgical risk. Different access routes have been used for TAVI, with percutaneous transfemoral being the preferred approach ...
Resident macrophages densely populate the normal arterial wall, yet their origins and the mechanisms that sustain them are poorly understood. Here we use gene-expression profiling to show that arterial macrophages constitute a distinct population among ...
For patients with genetically triggered thoracic aortic disease, the morbidity and mortality associated with reoperation are high, making endovascular treatment an appealing option. We evaluated the short- and mid-term outcomes of different applications of endovascular intervention in such patients.
Autophagy is critical in the maintenance of cellular protein quality control, the final step of which involves the fusion of autophagosomes with lysosomes. Cathepsin-L (CTSL) is a key member of the lysosomal protease family that is expressed in the murine ...
