ABSTRACT Objectives Our objective was to examine intermediate-term survival and reinterventions in unselected patients, stratified by indication, who received a Freestyle® bioprosthesis as a full aortic root replacement. Methods Data from medical records were retrospectively collected for patients who had aortic root replacement using Freestyle® bioprostheses between 1999 and 2018 at six North-Atlantic centers. Survival status was extracted from national registries and results stratified for indication for surgery. Results We included 1030 implantations in 1008 patients with elective indications for surgery: aneurysm (39.8%), small root (8.3%) and other (13.8%), and urgent/emergent indications: endocarditis (26.7%) and Stanford type A aortic dissection (11.4%). Across indications, 46.3% were non-elective cases and 34.0% were reoperations. Median age was 66.0 years (IQR 58.0-71.8) and median follow-up was 5.0 years (IQR 2.6-7.9). Thirty-day mortality varied from 2.9% to 27.4% depending on indication. Intermediate survival for 90-day survivors with elective indications were not different from the general population standardized by age and sex (p-values 0.95, 0.83 and 0.16 for aneurysms, small roots and other, respectively). In contrast, patients with endocarditis and type A dissection had excess mortality (p-values
