Abstract

Background The Global Registry for Endovascular Aortic Treatment (GREAT) is a prospective observational multicenter cohort registry that was initiated in November 2011. The aim of the GREAT is to collect contemporary real-world data on the performance of all Gore aortic endografts in the treatment of multiple aortic pathologies. The primary and secondary objectives, design, and future directions of the GREAT are described. Methods The GREAT aims to enroll 5000 consecutive patients with Gore thoracic and abdominal aortic endografts from multiple centers throughout the world. The GREAT has broad inclusion criteria with minimal exclusion criteria to reflect real-world practice such as including off-label use, nonstandard indications and devices deployed outside instruction for use. Follow-up will extend to 10 years providing major insights into the long-term durability and behavior of Gore aortic endografts. Primary end points include the incidence and timing of (1) endoleak of any type, (2) endograft migration and/or stent fracture, (3) endograft explantation, and (4) aortic rupture. Secondary end points include the following: (1) incidence of serious device events by pathology, (2) incidence of serious device events by aortic segment (ascending aorta, arch of aorta, descending thoracic aorta, abdominal aorta), (3) long-term survival by pathology, and (4) aorta-related mortality by pathology. Results As of June 2015, 2960 patients have been enrolled into the GREAT from 78 centers in Europe, the United States, Australia, New Zealand, and Brazil. The majority of patients and centers are from Europe and the United States. Completion of enrollment is anticipated to be in 2017 with interim results planned to be published during enrollment and on follow-up. Conclusions Upon completion, the GREAT will be among the largest clinical registry to date of abdominal and thoracic aortic devices manufactured by a single sponsor. It will provide valuable real-world data on the use and durability of Gore aortic endografts in the treatment of a variety of aortic pathologies and devices deployed within and outside instruction for use.
