Dr. Marino Labinaz is a Cardiologist and Director of the Intensive Cardiac Care Unit at the University of Ottawa Heart Institute. Also, he is Professor of Medicine (Cardiology) at the University of Ottawa.


Dr. Labinaz earned his undergraduate degree and did his medical training at Queen’s University in Kingston, Ontario, followed by a three-year residency in Internal Medicine at the University of Western Ontario in London. Following training in Cardiology, he completed a two-year interventional fellowship at Duke University Medical Center in Durham, North Carolina, after which, in 1994, he returned to the Heart Institute as a full-time member of the Division of Cardiology.

Dr. Labinaz is involved in all aspects of interventional cardiology, including establishing and maintaining programs in intravascular ultrasound, percutaneous closure of atrial septal defects, patent foramen ovales and perivalvular leaks. He established a stand-alone interventional program in Thunder Bay, Ontario, and served as its Medical Director for two years. He and Dr. Marc Ruel created a new program for percutaneous aortic valve implantation at the Heart Institute. Dr. Labinaz was involved in developing STEMI. He has chaired a Cardiac Care Network panel on the Utility of Primary Angioplasty for Acute Myocardial Infarction for Ontario.

He has served as the site principal investigator in over 30 clinical trials and has been a contributing co-investigator in another 30 clinical trials. Dr. Labinaz has also served on the Steering Committee of several international multicentre trials. He has received peer-reviewed funding from the Heart and Stroke Foundation and has served as co-principal investigator on a number of grants from the Canadian Institutes of Health Research.

Dr. Labinaz has published over 185 research publications, presentations, book chapters and reviews.

Research and clinical interests
