Hans-Joachim Schäfers

Hans-Joachim Schäfers (born August 9, 1957 in Lünen ) is a German surgeon, cardiac , thoracic and vascular surgeon and university professor in the clinic for thoracic, cardiac and vascular surgery of the medical faculty of Saarland University in Homburg / Saar . He is known for his work in the fields of aortic valve reconstruction, aortic surgery and pulmonary endarterectomy .

Life

Hans-Joachim Schäfers studied medicine at the University of Essen from 1976 to 1982 . There he received his doctorate magna cum laude in 1982 . After his military service, he completed his surgical training at the Hannover Medical School . He supplemented this with a one-year fellowship in the Department of Thoracic Surgery at the University of Toronto with a focus on lung transplantation . From 1991 he was senior physician at the Clinic for Cardiac, Thoracic and Vascular Surgery at the Medical University of Hanover and completed his habilitation in 1992. In 1995, he initially took over the provisional management of the Clinic for Thoracic and Cardiovascular Surgery at the Saarland University Hospital in Homburg. In spring 1996 he was appointed director of the clinic and full professor of surgery. He has taken on various tasks in the academic self-administration of the medical faculty of Saarland University and has led numerous research projects in cardiac and thoracic surgery. In addition to a wide range of activities in cardiac and thoracic surgery, his special clinical focus includes operations for aortic aneurysms (especially thoracic aortic aneurysms), heart valve reconstruction, especially aortic valve reconstruction, and operations for pulmonary hypertension .

Scientific contribution

The initial scientific work of Hans-Joachim Schäfers concentrated on the areas of heart and lung transplantation. During his stay at the University of Toronto (scholarship from the German Research Foundation) he dealt with the problem of bronchial complications after a lung transplant. In both Hanover and Homburg, he initiated important research projects to clarify and avoid bronchial complications and to reduce ischemia-reperfusion damage after a lung transplant. Later research projects during his time in Homburg included special aspects of functional mitral valve reconstruction and aortic surgery. Further projects dealt with the clarification of intestinal perfusion disorders after cardiac operations and the development of aortic aneurysms in congenital defects of the aortic valve , especially the bicuspid aortic valve and the unicuspid aortic valve. Building on his activities in the treatment of pulmonary hypertension, he worked on approaches to improve pulmonary endarterectomy. Over the past 20 years a number of different projects have focused on developing and improving techniques for aortic valve reconstruction. The concepts have been adopted by other surgeons.

Membership in international scientific associations

Schäfers is or was a member of numerous national and international scientific societies:
