This technique can potentially enhance patients' comfort and, by reducing post-operative morbidity, promote lowering the length of stay and global costs. Medicine Standardized Technique of Aortic Valve Re-implantation for Valve-sparing Aortic Root Replacement Reza Tavakoli1,2, Guillaume Lebreton1, Max Gassmann2, Peiman Jamshidi3, Pascal Leprince1 1Department of Cardiovascular and Thoracic Surgery, Pitie Salpetriere University Hospital, Assistance Publique, Hopitaux de Paris (APHP), Institut de Cardiologie, 2Institute of Veterinary Physiology and Zurich Center for Integrative Human Physiology, University of Zurich, 3Herzzentrum Hirslanden, Klinik St Anna Valve-sparing aortic root replacement has the advantage of preserving the patient's own aortic valve. The complexity of the reported techniques to date restricts their use to a limited number of cardiac surgeons. This protocol describes step-by-step a standardized technique reproducible by a greater number of cardiac surgeons.
