Abstract:
Objective To prove that valve sparing aortic root reconstruction may have an impact on the outcome and longevity of the repair for patients with acute type A aortic dissection.Methods Clinical data of 98 consecutive AAAD patients undergoing the valve sparing aortic root reconstruction were analyzed.The postoperative follow-up and the clinical effect of the procedure were retrospectively analyzed.Results Pre-operative grade of aortic insufficiency was(2.3 ± 0.5), CPB-time was (217.8 ± 43.1)min, aortic cross clamp time was(142.7 ± 37.4)min and stay on ICU (11.1 ± 5.7) days, while hospitalisation was(14.3 ± 3.2) days.8 patients(8.2％) died peri-operatively.None of the early deaths were valve-related.Rethoracotomy rate was 3.1％.All patients followed up(19.3 ± 7.6) (6-68) months.Survival at 1 year was 90.8％.Freedom from valvular reoperation was 97.9％ at 3 years.At last investigation, mean grade of aortic insufficiency for AADA was 0.5 ± 0.3 (0-3).Conclusion Regardless of the underlying indication, the aortic valve preserving reimplantation technique can be performed with favourable functional results.
