Outcomes of Sutureless/Rapid Deployment Valves Compared to Traditional Bioprosthetic Aortic Valves

Background. Advancements in technology have changed the treatment of aortic arch pathologies. Specifically, the introduction of the frozen elephant trunk technique has allowed one-stage treatment of pathologies that would have otherwise required a two-stage procedure. We present the early outcomes of a novel frozen elephant hybrid stent graft. Methods. Between August 2015 and July 2019, 39 patients (56% male; mean age 67 +/- 11years) underwent an arch reconstruction with a novel hybrid stent graft in four different Canadian centers. The most common indication for surgery was arch aneurysm (31%) followed by acute dissection (28%). All patients were prospectively followed with clinical and imaging assessments. Results. The device was successfully implanted in all patients. There were 3 perioperative deaths (8%). Transient spinal cord injury occurred in 5 patients (13%); all had complete neurologic recovery before discharge.
