The place of research and the role of academic surgeons in cardiac surgery.

The development of the discipline of cardiac surgery was, to a large extent, guided by the vision and research of its pioneers. On the basis of their efforts, all the different areas of cardiac surgery were able to evolve including coronary artery bypass grafting, heart valve surgery, surgery of the aorta, congenital heart surgery, surgery for rhythm disorders including the implantation of pacemakers and defibrillators, and surgical treatment of advanced heart failure (for example, heart transplantations and mechanical circulatory support). The continued existence of cardiac surgery and its role in medicine in general will depend, to a significant extent, on the future research activities of its protagonists. Cardiac surgeon-scientists will play a pivotal role since they combine clinical experience with scientific knowledge and intuition which make them able to direct research to topics which will matter in the future. However, research costs money, and state or national funds will be not sufficient to support research as much as is necessary. Funding from third parties such as industry will increasingly be required. Due to this, however, the cardiac surgeon-scientist faces various challenges such as the evaluation of his skill in acquiring funds, conflicts with current ethical standards, conflicts of interest when receiving money from industry, and, as a result of the tough competition in this field, the temptation to commit fraud. The head of a department of cardiac surgery holds an important function as his initiative is decisive for the development of visions for the future and for the employment of surgeon-scientists who pursue visionary research. It will take the combined efforts of surgeon-scientists and departmental heads not only to maintain but to extend the position of cardiac surgery in medicine and society even further.
