Xiaogang Sun, Professor, Chief Physician and Doctoral Advisor. He currently serves as the Deputy Director of the Surgical Management Committee and the Deputy Director of the Vascular Surgery Ward 3 at Fuwai Hospital, Chinese Academy of Medical Sciences. He is also a standing committee member of the National Expert Committee on Cardiovascular Diseases, Vascular Surgery, and a member of multiple national expert pools, including the Chinese Medical Association's Medical Appraisal Expert Pool. He was a visiting scholar at Massachusetts General Hospital, affiliated with Harvard University, and at the Reagan Medical Center, affiliated with UCLA. He serves as an editorial board member for several core journals, including "Chinese Circulation Journal", "Chinese Journal of Thoracic and Cardiovascular Surgery", "Chinese Medical Journal (English Edition)", and "Journal of Precision Medicine".

From 1992-1995, he pursued a Master's degree in Cardiothoracic Surgery at Peking Union Medical College, under the mentorship of Academician Xiaodong Zhu, focusing on the research of artificial biological heart valve systems. From 2000-2003, as a PhD student in Cardiothoracic Surgery at the same institution under Academician Shengshou Hu, he pioneered and completed experimental studies on the intracorporeal implantation of bovine jugular vein valves. With nearly 30 years of experience in cardiac surgery at Fuwai Hospital, he has received rigorous and systematic training in both professional theory and clinical skills, establishing a solid comprehensive professional foundation. To date, he has independently performed over 6,000 various types of cardiac surgeries, including congenital heart disease, ischemic heart disease, valvular heart disease, and various aortic diseases, achieving excellent clinical outcomes. His current focus is on clinical and research work related to aortic diseases, specializing in surgical treatments for various pathologies of the aortic root, including dissections, complex aortic arch conditions, and repairs of aortic valve pathologies through various techniques. Additionally, he has achieved satisfactory clinical results in the emergency treatment of critical aortic diseases, such as acute Type A aortic dissection and ruptured thoracoabdominal aortic aneurysms. His success rate for surgeries involving aortic diseases and adult cardiac diseases consistently exceeds 99%.

In terms of research, he is dedicated to establishing treatment systems for Type A aortic dissection at the root, perfecting repair strategies for bicuspid aortic valve anomalies and other aortic valve pathologies, exploring thoracoabdominal aortic replacement under different extracorporeal circulation modes, and developing and promoting new paradigms for neuroprotection in aortic arch surgery. In 2017, he was the first internationally to apply aortic balloon occlusion technology to total arch replacement and stent elephant trunk surgery, safely and effectively reducing the deep hypothermic circulatory arrest time to 3-5 minutes, a technique innovation honored as the "TOP 5" by the American Association for Thoracic Surgery (AATS). He has led and completed multiple key provincial and institutional projects, with current research funding exceeding 3 million yuan. As the first or corresponding author, he has published over twenty SCI research papers in top international journals in the field of thoracic and cardiovascular surgery, such as JTCVS, ATS, EJCTS, and JVS. He has been frequently invited to speak at top international academic conferences, including the annual meetings of the European Society for Cardio-thoracic Surgery, the American Thoracic Society, and the New York Aortic Surgery Symposium.
