Patients
This retrospective study was approved by our local ethics committee. Data was collected prospectively in our institutional database. From October 2013 to December 2019, 56 consecutive patients underwent a complete aortic arch replacement using the E-vita Open hybrid prosthesis. All the procedures were performed by two experienced surgeons. Main underlying diseases were degenerative aneurysm (n=27) and type A acute aortic dissection (n=18). Patients characteristics are presented in Table 1.
As we gained experience (Figure 1), indications expanded to more complex diseases, and the technique was standardized. We compared the surgical technique and operative results between our early (Group I, October 2013-December 2017, n=25) and late experience (Group II, January 2018-December 2019, n=31).
