Tristan D. Yan is a Consultant Cardiothoracic Surgeon, Professor of Cardiovascular and Thoracic Surgery at the Macquarie University Hospital and Associate Clinical Professor at the University of Sydney, Department of Cardiothoracic Surgery, Royal Prince Alfred Hospital and Sydney Adventist Hospital in Sydney, Australia.

Professor Yan graduated from the University of New South Wales (UNSW) with Bachelor of Science (Medicine), Bachelor of Medicine and Bachelor of Surgery. He had also completed three postgraduate higher degrees, Master of Surgery (USyd), Doctor of Medicine (UNSW) and Doctor of Philosophy (UNSW). He was trained at Royal Prince Alfred Hospital and St Vincent’s Hospital in Sydney and then obtained Cardiothoracic Surgery Fellowship from the Royal Australasian College of Surgeons. Following advanced specialty fellowships in the United States, England, Scotland and Germany, he is fully trained in major thoracic aortic surgery, minimally invasive cardiovascular surgery, and minimally invasive thoracic surgery. He has authored or co-authored more than 200 articles and textbook chapters, with an h-index of 32 and approximately 4000 citations. He is the Chairman of CORE Group International, and responsible for establishing and organizing the world’s largest multi-institutional Aortic ARCH Registry, consisting of 12,500 patients. He is also the founder and the Editor-in-Chief of the Annals of Cardiothoracic Surgery.

Surgical Expertise

Professor Tristan Yan is dedicated to surgical innovations. He applies the latest pioneering techniques to minimize surgical trauma and thus achieves a more rapid and comfortable recovery for his patients. He first completed his surgical fellowship with Paul Sugarbaker in the United States, one of the most prominent surgeons in the world. He was then closely trained by the pioneer of Minimally Invasive Thoracic Surgery, Mr. William Walker, in Edinburgh, where he mastered the technical expertise of video-assisted thoracoscopic surgery (VATS) to perform complex lung resections, such as lobectomy and segmentectomy.

He underwent a comprehensive Aortic Surgery Fellowship Program at the largest Aortic Surgery Center in the UK, where he was trained primarily on minimally invasive aortic valve replacement, aortic root, arch and thoracic aortic surgery. He was then mentored by Professor Fred Mohr, Professor Michael Borger and Professor Martin Misfeld on Minimally Invasive Cardiac Surgery at the Leipzig Heart Center, Germany. He specialises in minimally invasive aortic root replacement, ascending aortic replacement and hemiarch replacement - a composite procedure that he named the "Mini-Bentall" procedure.

Academic Achievements

Throughout his career, he has always aimed for the highest integrity towards clinical data, as he strongly advocates evidence-based medicine, rigorously pursues high-level evidence, continuously publishes research articles in high-impact journals, and actively promotes wide dissemination of research information in a timely, accurate and scientific manner. At least 40 of his papers have been published in journals with an impact factor above 4 and in the majority of these he is the first, or the corresponding author. During the past year his team has published more than 30 scientific publications.


Professor Yan is the founder and Editor-in-Chief of the Annals of Cardiothoracic Surgery (ACS). This journal reflects his unique vision in cardiothoracic surgery, in that ACS will become a comprehensive video resource of cardiothoracic surgical procedures that truly embraces today’s technological and multimedia environment. The innovative format is further epitomized by its highly scientific Systematic Review and Meta-analysis and richly illustrated Art of Operative Techniques sections. As the pioneering format of ACS has not been seen in any other surgical journals, its themed issues, accompanied by video articles from leading surgeons, may become a model for future surgical journals. The uniqueness of ACS offers an unparalleled insight into cardiothoracic surgery. ACS has been accepted for inclusion by PubMed Central.

Professor Yan has several other editorial commitments including Executive Editor-in-Chief (Cardiovascular Surgery) for the Journal of Thoracic Disease, Associate Editor (Cardiac Surgery) of the European Journal of Cardiothoracic Surgery and CTSNet Editor for Journal and News Scan section of the Cardiothoracic Surgery Network. He is an external reviewer of National Institute of Clinical Evidence (NICE) for Health Technology Assessment. He is also on the journal review board for 15 journals, including Annals of Surgery, Annals of Surgical Oncology, British Journal of Cancer, British Journal of Surgery, Cancer, Cochrane Systematic Review Protocol, and Heart, amongst others.


Professor Yan’s team of twenty individuals is among the most productive in the world for clinical research and evidence synthesis in surgery, with a specific focus on cardiovascular and thoracic surgery. He has personally trained each member of his team in systematic review, meta-analysis, propensity score analysis and academic writing. He is currently co-supervising two PhD Research Fellows. Within the last five years he has successfully co-supervised more than ten research candidates. His students have national training numbers, research fellowship positions and fast career progressions, with some of them achieving more than 50 publications. This highlights the coherence and efficient collaboration between his team that he has personally fostered. He also provides clinical teaching and mentoring to the junior surgical registrars, preparing them for the next level of their clinical responsibility.

International Collaborations

Professor Yan is the Chairman of Collaborative Research (CORE) Group International, a cohesive and highly networked research organization in cardiovascular, thoracic and oncologic surgery, which is strongly supported by his international collaborators. He has established the largest multi-national Aortic ARCH Projects, involving 12,500 patients from 36 leading aortic centers from 10 countries, and the VATS Lobectomy Consensus Group, involving 50 world experts in Minimally Invasive Thoracic Surgery. Under his leadership, CORE Group promotes clinical guidelines in conjunction with the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS). CORE Group is also in the process of obtaining an international accreditation from National Institute for Health and Clinical Excellence (NICE) as a sign of high standard information development.
