E-Vita OPEN NEO Hybrid Stent Graft: A New Frontier for Total Arch Replacement

The ever-changing landscape of aortic arch surgery necessitates a constant update on the available devices and technologies for the contemporary management of complex aortic diseases. The E-Vita OPEN NEO hybrid stent graft system offers a unique approach for aortic arch replacement with the frozen elephant trunk technique. In contrast to its predecessors and other commercially available devices, it fits to each individual patient's needs by allowing for more proximal graft anastomosis. We sought to present our initial experience with the novel E-Vita OPEN NEO hybrid stent graft system focusing on its description, optimal graft selection, operative technique, and results in a clinical setting.We prospectively collected data on all patients in whom the E-Vita OPEN NEO device was used between October 2020 and May 2021. The primary outcome was perioperative or with 30-day mortality. Secondary outcomes were the incidence of neurologic complications (stroke and spinal cord ischemia) and endoleak on a postoperative computed tomography angiography.During the study period, six patients received the novel hybrid stent device. The mean patient age was 59.3 ± 13.3 years and 83% were male. Two patients were operated on an emergent setting due to acute Stanford type A aortic dissection and there were two reoperations in patients with a history of previous repaired type A dissection. There was no perioperative or 30-day mortality and none of the patients exhibited adverse neurologic events. Two patients required completion thoracic endovascular repair due to type Ib endoleak. One patient died after a prolonged stay in the intensive care unit due to pneumonia and multiorgan failure.This novel device adapts to each patient's characteristics and offers a curative option for acute and chronic aortic arch and descending aortic conditions such as aneurysmal disease and aortic dissection. In addition, it offers an excellent landing station for potential endovascular therapies and allows for complete aortic remodeling.
