International E-vita open registry
The E-vita open hybrid stent-graft enables successful one-stage repairs of complex pathologies of the ascending aorta, aortic arch, and descending aorta. To evaluate the efficacy and durability of this treatment concept, the International E-vita open registry (IEOR) was initiated in 2008. 416 patients from 10 European centers were recruited, separated into 138 (33.2%) acute dissection cases, 142 (34.1%) chronic dissection cases, and 136 (32.7%) patients with multisegmental thoracic aneurysmal disease. In-hospital mortality was 16%, 14%, and 13% for each of the three groups, respectively, and stroke and spinal cord injury rates ranged between 5-7% and 3-9%. Survival after 5 years was 79%, 86%, and 78% for acute dissection, chronic dissection, and multisegmental aneurysmal patients, with freedom from open aortic surgery after 5 years at 96%, 94% and 82%. Findings from IEOR demonstrate the importance of the registry as an important tool for developing guidelines and frameworks in the management of this complex pathology.
