Abstract:
Objective:To evaluate the outcomes of aortic root repair in acute type A aortic dissection (ATAAD) with aortic sinus involvement.Methods:The clinical data of patients with ATAAD involving the aortic sinus and an aortic root diameter of ≤45 mm who were treated from January 1, 2015, to December 31, 2016, were collected. Patients were divided into group A (involvement of one aortic sinus or part of one aortic sinus) and group B (involvement of more than one aortic sinus). The effectiveness of aortic root repair in ATAAD with sinus involvement was analyzed by comparing the preoperative imaging characteristics and postoperative results between the two groups.Results:The study cohort comprised 155 patients, including 100 patients in group A and 55 in group B. There were no differences between the two groups in baseline characteristics, aortic root diameter, 30-day mortality, and complication rates. During an average follow-up of(49.1±14.6) months, there was no difference between the two groups in the survival rate (92.0% vs. 89.5%, P=0.61). The aortic root diameter at follow-up showed no progressive expansion compared with preoperatively in either of the two groups[(38.1±3.6) mm vs. (37.9±3.5)mm, P=0.92, A; (38.4±4.1) mm vs. (38.3±3.6) mm, P=0.74, B]; furthermore, there was no difference between the two groups in aggravation of aortic regurgitation. Conclusion:Aortic root repair achieves satisfactory medium-term outcomes in ATAAD with more than one aortic sinus involved, but the long-term outcomes need to be evaluated.
