Objectives: Reimplantation valve-sparing aortic root replacement has been increasingly performed with improving perioperative and midterm results. However, extending the age criterion in patient selection remains a debate. This study reviews the results of reimplantation valve-sparing aortic replacement in patients greater than 60 years of age. Methods: During a 51-month period, 63 patients with aortic root aneurysms underwent reimplantation valve-sparing aortic root replacement. The Gelweave Valsalva™ prosthesis (TERUMO CardioVascular Systems Corp., Ann Arbor, MI, USA) was used in all but one case. The patients were predominantly male, and the mean age was 67 years (range, 61-83 years). Four patients had congenital bicuspid aortic valves, and cusp repair was required in one patient. The mean follow-up was 25 months (range, 1-51 months). Results: There were one hospital and two late deaths. Overall survival at 51 months was 84 ± 9.9%. During follow-up, one patient developed severe aortic incompetence (AI) requiring an aortic valve replacement (AVR). Freedom from reoperation at 51 months was 92.8 ± 6.8%. Moderate AI was present at latest echocardiogram in one patient. Freedom from moderate or severe AI at 51 months was 90 ± 9.4%. There was no episode of endocarditis on follow-up. Univariate analysis demonstrated that no preoperative or intraoperative factor was a predictor for late reimplantation failure. Conclusions: Reimplantation valve-sparing aortic root replacement in patients greater than 60 years old can be performed with satisfactory perioperative and midterm results. Long-term results are needed to define the durability of this technique and its role in this subset of patients.
