OBJECTIVES: The E-vita Open hybrid stent graft is intended to achieve one-stage treatment of the proximal and distal thoracic aorta down to the mid-thoracic level in cases of acute (AAD) or chronic (CAD) type I aortic dissection and complex thoracic aortic aneurysm (TAA). We report our long-term results up to 10-year experience. METHODS: From February 2005 until March 2015, 178 consecutive patients (mean age 59 ± 11 years) underwent surgery using the E-vita Open hybrid graft for AAD ( n = 96), CAD ( n = 43) or TAA ( n = 39). Pre-, intra- and postoperative variables, influential procedural improvements and follow-up data including aortic remodelling analyses are presented. RESULTS: Overall 30-day mortality was 10%, 10% for AAD, 7% for CAD and 13% for TAA. Univariable analysis identified low left ventricular ejection fraction, peripheral arterial disease, chronic obstructive pulmonary disease and severely compromised haemodynamics as risk factors for in-hospital death. Logistic regression analysis defined compromised haemodynamics and duration of cardiopulmonary bypass as significant. After 7 years, estimated survival was 55% for AAD, 74% for CAD and 73% for TAA patients. Freedom from aorta-related late death was 94%, 91% in AAD, 100% in CAD and 97% in TAA. Positive or stable aortic remodelling down to the stent graft end was achieved in 92% AAD, 82% in CAD and full aneurysmal exclusion in 88%. Further downstream, negative remodelling was observed in 27% of the AAD, 41% of the CAD and 22% of the TAA patients. Freedom from endovascular intervention downstream was 96% in AAD, 75% in CAD and 74% in TAA patients. Freedom from thoraco-abdominal surgery was 97%, 65% and 93%, respectively. CONCLUSIONS: The E-vita Open hybrid stent graft renders durable long-term performance without any proximal endoleakage or graft failure over time and represents the ideal landing or docking zone for either thoracic endovascular thoracic repair or thoraco-abdominal surgery, if required. No reinterventions were necessary down to the end of the stent graft, proving that the disease is overcome along the hybrid graft down to mid-thoracic level.
