• W2891331085 abstract "BackgroundValve-sparing aortic root replacement (VSRR) is an established treatment for aortic root pathology for trileaflet valves. The safety and durability of VSRR in bicuspid aortopathy is unclear. In this study, outcomes of performing VSRR in the setting of bicuspid and trileaflet valves were compared.MethodsAn institutional database identified 294 patients who underwent VSRR from 2005 to 2017. Of these, 225 had trileaflet valves and 69 had bicuspid valves. Patients were followed prospectively and had annual postoperative echocardiograms. Propensity-matched comparisons were made between trileaflet and bicuspid valve patients.ResultsThe average patient age for trileaflet valves was 46.0 ± 13.5 versus 42.7 ± 12.2 years for bicuspid patients (p = 0.07). There was a higher presence of preoperative >2+ aortic insufficiency (AI) present in bicuspid patients (63.8%) compared with trileaflet patients (31.1%) (p < 0.01). Mean follow-up was 39 months and was 98% complete. At 5 years, the cumulative incidence of >2+ AI and aortic valve replacement (AVR) was 2.0% and 4.3% in trileaflet patients and 7.7% (p = 0.75) and 7.7% (p = 0.81) in bicuspid patients. Preoperative >2+ AI was not predictive of >2+ postoperative AI (p = 0.62) nor AVR (p = 0.49). Five-year survival was no different between groups (trileaflet: 98%, bicuspid: 84%, p = 0.24).ConclusionsVSRR can be safely and effectively performed in patients with trileaflet and bicuspid valves. Operative outcomes and valve function were equivalent in bicuspid and trileaflet patients in midterm follow-up. Performance of VSRR is a viable term option in the setting bicuspid aortic valve aortopathy.
