Aortic root remodeling was first published in the 1980s. Today's aortic root remodeling is geometrically precisely defined and indicated in every patient with aortic valve regurgitation in aortic root aneurysm. The aim of the work is to evaluate the medium-term results of aortic root remodeling in our conditions and the risk factors that have an impact on this stability. The work included 103 patients undergoing aortic root remodeling from January 2011 to December 2013. Patient follow-up was performed by echocardiographic control in correlation with the recommendations of the international AVIATOR registry. The analysis of patient survival focused on survival without reoperation and without the finding of aortic regurgitation of the third and higher degree recorded the hemodynamic stability of aortic root remodeling 4 years after surgery at the level of 89% and 6 years after the surgery at the level of 86%. Univariate regression analysis did not identify any of the compared factors and intraoperative parameters as factors affecting remodeling stability and survival. Remodeling of the aortic root and reimplantation of the aortic valve today represent an optimal therapeutic strategy for patients with aortic regurgitation and aortic root aneurysm in appropriate anatomical conditions. If the required procedures are followed, the remodeling of the aortic root brings very optimistic results from the point of view of medium-term as well as long-term follow-up.
