About

Dr. William C. Vezina is a pioneering cardiothoracic surgeon whose research has significantly advanced the field of robotic-assisted coronary artery bypass grafting (RA-CABG). His work focuses on refining minimally invasive surgical techniques, particularly for complex coronary artery disease. Dr. Vezina’s most influential study, "Long-Term Angiographic Follow-Up of Robotic-Assisted Coronary Artery Revascularization" (2012, 64 citations), provides critical evidence on the durability and efficacy of robotic procedures, demonstrating excellent long-term graft patency. He has also explored specialized applications, such as robotic bypass for aberrant coronary anatomy, and importantly, investigated postoperative complications. His 2021 study on hiatal hernia progression after RA-CABG, analyzing CT scans of 491 patients, is a landmark contribution to understanding and managing this underrecognized complication. By systematically evaluating both outcomes and risks, Dr. Vezina has helped establish safety protocols and refine patient selection for robotic cardiac surgery. His work bridges the gap between innovative technology and evidence-based practice, making him a key figure in the evolution of minimally invasive coronary revascularization.
