Choosing aortic valve plasty for aortic root/ascending aorta repair

Abstract

Aim: The study was designed to evaluate the outcomes of aortic valve reimplantation (David procedure), as well as various techniques of aortic root reconstruction.Methods: The results of 84 valve-sparing operations for thoracic aortic aneurysms and dissections were analyzed at B. Petrovsky Russian Research Center of Surgery over a period from 2007 to 2016. The first group (n = 42) consisted of patients after David procedure, the second group (n = 38) included patients after different methods of aortic root repair (fixation of commissures, leaflets plication, sinotubular ridge repair). 5-year results of surgical treatment were assessed.Results: David procedure is characterized by good long-term results. There was no in-hospital and 5-year mortality in the first group, while 2 (5.3%) patients in the second group died in the early postoperative period. In both groups the reoperation rate was 2.4% and 8.3% respectively.Conclusion: Valve-sparing aortic root repair is characterized by good survival rate, high freedom from reoperation and low incidence of complications.
