[The Long-term Results of Valve Sparing Aortic Root Replacement and Aortic Cusp Repair for Aortic Regurgitation].

Abstract

We reported our long-term results of valve sparing aortic root replacement (VSRR) and aortic cusp repair for aortic regurgitation( AR) were satisfactory. Three hundred twenty-seven patients had VSRR, and 164 patients of them had aortic cusp repair for prolapse. At 10 years after the operation, the overall survival was 91.5%, the freedom from more than mild recurrent AR was 71.2%, and the freedom from aortic valve reoperation was 82.0%. As for the aortic cusp repair technique, there was no significant difference in the mid-term results of the recurrent AR and reoperation for the aortic valve between the central plication technique and the resuspension technique (two layers of continuous mattress sutures placed the entire length of the free margin of the aortic cusp). The resuspension technique might be useful for repairing the aortic cusp with prolapse. Furthermore, among the patients with acute aortic dissection, connective tissue disease, or aortitis, the long-term results of VSRR and aortic cusp repair were also satisfactory.
