The sponsor stated that using the E‑vita open plus could allow repair of the thoracic aorta in a single procedure, when a 2-stage procedure would otherwise be necessary. It claimed that this would consequently reduce overall length of stay in hospital and reduce the risk of complications needing hospital treatment. The clinical evidence consisted of the study by Jakob et al. (2011), which contained no comparative data about resource use during other aortic repair techniques. The review and meta-analysis carried out by the sponsor focused on clinical outcomes rather than resource implications.
