Lam, Buu-Khanh

Dr. Buu-Khanh Lam is a Cardiac Surgeon and Director of the Valve Clinic at the University of Ottawa Heart Institute, and he is Associate Professor of Surgery and Co-Director of Surgery Undergraduate Education, Faculty of Medicine at the University of Ottawa.

Background

Dr. Lam received his MD in 1994 from McGill University in Montreal. He trained in General Surgery at McGill University before completing his Cardiac Surgery residency at the Heart Institute. Dr. Lam was certified in Cardiac Surgery as a Fellow of the Royal College of Physicians and Surgeons of Canada (FRCPC) in 2000.

Dr. Lam pursued his clinical research training at the Cleveland Clinic Foundation as a Research Fellow of the Heart and Stroke Foundation and the Canadian Institutes of Health Research. He was an International Fellow at the Cleveland Clinic Heart Center where he completed his master's degree in Public Health and Epidemiology, with a special emphasis on advanced parametric outcomes analysis. He was also a Clinical Scholar of the Cleveland Clinic Department of Cardiothoracic Surgery and completed a surgical fellowship in complex coronary and valve surgeries, minimally invasive valve surgery techniques, aortic surgery and atrial fibrillation surgery.

Dr. Lam is the Canadian lead in a North American and international effort to promote the treatment of lone atrial fibrillation via minimally invasive surgical techniques. He was the first Canadian surgeon to perform a thoracoscopy-assisted ablation for lone atrial fibrillation; he is training other Canadian surgeons to perform this procedure.

As the Surgical Undergraduate Medical Education Site Director at the Heart Institute, he has reorganized the entire curriculum by restructuring the objectives, course material, teaching sessions and evaluation/feedback mechanisms. This strategy has increased the number of electives and selectives requested by students.

Research and clinical interests

Dr. Lam’s clinical research interests include valve outcomes analysis, medical informatics, therapeutic options for the treatment of ischemic mitral regurgitation, atrial fibrillation and the effects of simulation in surgical education.
