Objective: To report the early and mid term results of patients who underwent aortic valve replacement (AVR) with a sutureless prosthesis in case of aortic valve reoperation (REDO) from an International prospective registry. Methods: Between March 2011 and September 2018, among the 957 patients included in the prospective observational SURE-AVR registry a total of 59 patients underwent REDO AVR with self-expandable sutureless aortic bioprosthesis in 17 International institutions. Preoperative, periprocedural and follow-up clinical and echocardiographic parameters, as well as clinical outcomes, were analyzed for all patientsResults: Patient age was 71.1 ± 10.3 years; 42.4% were female. Median logistic EuroSCORE II was 11.3%. The indications for REDO surgery were infective endocarditis (16.9%) and bioprosthetic structural valve dysfunction and degeneration (83.1%) and were performed in patients previously implanted with bioprostheses (n=47), mechanical valves (n=10) or transcatheter valves (n=2). Surgery was performed through median sternotomy in 52 (88.1%), mini-sternotomy in 3 (5.1%) and mini-thoracotomy in 4 (6.8%) cases. Concomitant procedures were performed in 20 cases (33.9%). Median intensive care unit stay was 2 days. Five-year survival was 96.3%. The mean transvalvular gradient at 1 year follow-up was 11.2 ± 5.2 mmHg. Early and late complications are reported in Table 1.Conclusions: Sutureless AVR in high-risk REDO surgery procedure is a safe and effective alternative to traditional AVR or transcathether valve in valve approach, providing satisfactory hemodynamic performance with excellent clinical recovery, both in the early and at mid-term follow up. Although the limited sample size, these results are encouraging and support the use of sutureless valves in the frame of REDO AVR surgery.
