Pioneering Contributions

Founded the Aortic Surgery Center at Beijing Anzhen Hospital in 2009, which the hospital describes as China's largest aortic disease diagnosis and treatment center.
The 2025 Annals of Cardiothoracic Surgery review refers to the 'Sun procedure' as the Chinese frozen elephant trunk strategy for acute type A aortic dissection, linking his name to a nationally adopted aortic arch repair approach.
Helped build Beijing Anzhen Hospital into a national training base for aortic surgery and a lead unit for Chinese aortic-disease treatment guidelines and expert consensus documents, according to the official department introduction.
