Background: We report our experience in aortic arch repair with the E-vita Open hybrid prosthesis and describe the changes in our technique over time. Methods: Between October 2013 and December 2019, 56 patients underwent a total aortic arch replacement with the E-vita Open hybrid prosthesis. Main indications were thoracic aorta aneurysm (n=27) and acute type A aortic dissection (n=18). We analyze the technique and results in the overall series, and compare both between our early (Group I, 25 patients) and late experience (Group II, 31 patients). Results: Overall in-hospital mortality was 7.1% (4), and permanent stroke and spinal cord injury were 3.6% and 1.8% respectively. 15 patients (26.8%) underwent a planned second procedure on the distal aorta: 13 endovascular, 1 open and 1 hybrid. Survival at 1 and 3 years was 90.7% and 80.7%. Group II included more patients with acute dissection (45.2% vs 16%, p=0.02), a higher rate of bilateral cerebral perfusion (100% vs 64%, p<0.001), left subclavian artery perfusion during lower body circulatory arrest (87.1% vs 0%, p<0.001), early reperfusion (96.8% vs 40%, p<0.001), and zone 0-2 distal anastomosis (100% vs 72%, p=0.02). In-hospital mortality (3.2% vs 12%) and permanent stroke (0% vs 8%) tended to be lower in Group II. Conclusions: Total arch replacement with E-vita Open hybrid prosthesis in complex thoracic aorta disease is safe. One-stage treatment is feasible when pathology does not extend beyond the proximal descending thoracic aorta. In any case, it facilitates subsequent procedures on distal aorta if needed.
