Dr John Tyberg

It is with great sadness that we announce the death of Dr. John Tyberg on April 10, 2022 at the age of 83 following a brief illness.

Dr. Tyberg was born in Grantsburg, Wisconsin, and received his BA at Bethel College, St Paul, Minnesota, his MD and PhD in a combined MD/PhD program at the University of Minnesota. He also trained at the Peter Bent Brigham Hospital, Harvard University; the University of California, San Francisco; and the Cedars-Sinai Medical Centre, Los Angeles.

He joined the University of Calgary in 1981 as a Senior Clinical Investigator of the Alberta Heart Foundation. In 1983, he became a Heritage Medical Scientist of the Alberta Heritage Foundation for Medical Research. He was twice a Visiting Scientist, first at the Imperial College of Science, Technology and Medicine, London, and later at St Mary’s Hospital, Imperial College of Science, Technology and Medicine, London. He became Emeritus Professor of Cardiac Sciences and Physiology and Pharmacology, at the University of Calgary in 2011, but continued his usual research activity until it was disrupted by the pandemic. He was widely recognized internationally for his many contributions to understanding complex cardiovascular physiology.

He was committed to his many graduate and post-graduate students and often followed them with pride through their careers after they moved on. His generosity was such that he welcomed many students, trainees, and colleagues from various local and external faculties into his laboratory to share ideas and to perform their studies in his lab.

Dr Joel Niznick

Peacefully on Friday, April 8, 2022, Joel Niznick passed away. His passing is an incredible loss to his family and friends and to the Ottawa community.

Niznick completed his Medical school at the University of Manitoba, his internal medicine training in Toronto and his cardiology subspecialty training in Ottawa. He led the development of the Ottawa Cardiovascular Centre (OCC), one of Ontario’s most advanced Cardiology care providers. Joel was a strong advocate and champion for excellence and continuity in patient care. He was a forward thinker and always was looking to ensure excellence in the delivery of care. He loved his patients and he thought of them like family that needed to be protected. He became a vital link in building community-academic hospital bridges.

The world has lost an extraordinary and admirable man who will be deeply missed by his family and friends.

Dr Malcom Arnold

We regret to inform you of the death of Dr. Malcom Arnold on February 18, 2022.

He will be remembered as a man committed to three passions: his faith, his family, and his work. Known for his character and integrity in all circumstances, his example of kindness, gentleness, steadfastness, and wisdom is celebrated by so many that knew him. He was a deeply devoted husband, committed father and cherished grandfather. The family aches in his absence and he will be missed yet are forever grateful for the legacy that he last left. They take great comfort knowing that his faith in the Lord is now being realized. His life was in service to many. As a physician for 38 years, he was a well-respected and significantly accomplished cardiologist, much of that with London Health Sciences Centre. He was also an admired church elder, actively involved with North Park Community Church for over 30 years.

Dr George Wyse

Dr. George Wyse, MD, PhD, professor emeritus at the Cumming School of Medicine (CSM), passed away peacefully alongside his wife of 58 years, Bonnie, in their home in Canmore on Jan. 6, 2022. 
Wyse, a world-renowned cardiac arrhythmia clinician-scientist and longtime member of the Libin Cardiovascular Institute (LCI), retired from clinical practice in December 2016. His contributions to the CSM and the institute are immeasurable. 

Wyse’s research career was also notable. During his 2017 UCalgary Lecture of a Lifetime presentation, he detailed two cardiac-arrhythmia research projects in which he held major leadership roles: the Cardiac Arrhythmia Suppression Trial (CAST) and the Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM). Both impacted the treatment of heart patients globally.

These studies, along with Wyse’s other work, resulted in more than 300 publications and more than 18,000 citations. He was the founding member of the cardiac electrophysiology group at UCalgary and former chief of cardiology.

Wyse received numerous awards during his career including the 2007 Distinguished Scientist Award from the Heart Rhythm Society, an Annual Achievement Award from the Canadian Cardiovascular Society in 2008, the Top 40 Alumni award (2007) and Distinguished Alumni award (2005) from the UCalgary.

He was also president of the Heart and Stroke Foundation of Alberta, Northwest Territories and Nunavut and a founding and long-serving member of the LCI board.

Dr Martial G. Bourassa

À l’Institut de cardiologie de Montréal, le 28 juillet 2020, à l’âge de 89 ans, entouré de l’amour des siens, est décédé Dr Martial G. Bourassa.

Depuis 1965, le Dr Bourassa était cardiologue à l’Institut de cardiologie de Montréal, et professeur titulaire à la Faculté de médecine de l’Université de Montréal depuis 1976. Il faisait partie de plusieurs sociétés scientifiques et y a occupé plusieurs présidences. Il est considéré comme l’un des pionniers de la cardiologie au Québec. Son nom est attaché à l’invention d’un cathéter, le cathéter Bourassa, utilisé en cardiologie tant au Canada et en Amérique du Nord qu’en Europe.
