Abstract

BACKGROUND
A composite valve graft replacement has been used for a variety of aortic root diseases. The aim of this study was to evaluate the mid-term results of this technique. MATERIAL AND METHOD: We conducted a retrospective analysis of aortic root composite valve graft replacements in 39 patients and these procedures were done at our institution between 1992 and 2009. The mean age of the patients was 49.2+/-16.4 years. The mean follow-up was 64.2+/-53.4 months (maximum: 176 months). RESULT: There were 4 hospital deaths (8.6%) due to emergency aortic dissection and 4 late deaths owing to several causes. The causes of late death were 2 ruptures of a remnant aneurysm, 1 subdural hemorrhage and 1 paravalvular leakage. The calculated survival rate was 93.5%, 85.0% and 85.0% at 1, 5 and 10 years, respectively. There were 3 cerebrovascular accidents during the follow up period. The rate of freedom from cerebrovascular accidents was 97.0%, 92.0% and 80.0% at 1, 5 and 10 years, respectively. All of these brain accidents were hemorrhage-related complications.
CONCLUSION
A composite valve graft replacement of the aortic root was associated with favorable results. So, this technique seems to be a good method to treat various aortic root diseases.
