Osami Honjo

Associate Professor 

Dr. Osami Honjo became Staff Cardiovascular Surgeon at The Hospital for Sick Children in July 2010, after completing his fellowship in Cardiovascular Surgery at The Hospital for Sick Children and St. Michael’s hospital, University of Toronto.

His clinical practice focuses on open heart surgery in neonates and infants, surgical palliation for single ventricle patients, mechanical cardiopulmonary support in pediatric population, and surgery for patients with adult congenital heart diseases.

Dr. Honjo’s academic interest in basic science has been mechanical circulatory support for neonates and infants with single ventricle physiology. Working with Dr. Glen Van Arsdell, he developed a mechanical pump system that is able to support the patients with cavopulmonary connection. This support system may be a way of neonatal surgical palliation for critically ill patients or a way of bridge to transplantation.

Dr. Van Arsdell and Dr. Honjo are currently conducting the first human study using this pump system in patients with hypoplastic left heart syndrome. His new study protocols include establishment of new circulatory support system in patients with single ventricle physiology that potentially eliminates 2 out of 3 staged surgical palliations. The other interest is to develop brain protection strategies for neonates and infants who require deep hypothermic circulatory arrest, for which Dr. Honjo obtained University of Toronto's 2010 Roscoe Reid Graham Scholarship in Surgical Science

Dr. Honjo’s academic interests in clinical research have been preoperative and intraoperative decision making on critically ill patients. His research primarily focuses on seeking for clinical predictors/factors that influences outcome, which improve the quality of surgeons’ decision making.

Dr. Honjo obtained his medical degree from the Shimane Medical University and PhD at Okayama University, Japan. He is a diplomat of the Japan Surgical Society (general surgery board), and Japanese board of Cardiovascular Surgery.
