Multicentre Experience of Sutureless Prostheses Inside Degenerated Stentless Aortic Valves and Bioroots.

OBJECTIVES: Patients with failed stentless aortic prostheses are a challenging population to treat, as reoperative procedures may be complex and catheter-based treatments are associated with a high rate of procedural events. Reoperative surgery using sutureless valves may be an alternative. METHODS: In this multicentre experience, we assess outcomes of 17 patients who underwent reoperative surgery using the Perceval valve (Corcym UK Limited, London, UK) inside Freestyle prosthesis (Medtronic Inc., Dublin, Ireland) or bioroots from 2018 to 2023. RESULTS: Mean age was 71.1 +/- standard deviation 15.1 years and mean EuroSCORE II was 13.5 +/- 15.8%, Society of Thoracic Surgeons Score was 5.9 +/- 11.7%. Mean transvalvular gradient at baseline was 25.3 +/- 19.9 mmHg and left ventricular ejection fraction was 53.5 +/- standard deviation 8.5%. In 70.6% (12/17), moderate or severe aortic regurgitation was present. Implant success was 100%. Aortic cross-clamp time was 44.5 +/- standard deviation 23.6 min. No patient needed a pacemaker and no mild paravalvular regurgitation occurred. Mean gradient was 12.5 +/- 4.7 mmHg; 30-day mortality was 5.9% (1/17). CONCLUSIONS: Rate of mortality was lower than predicted by EuroSCORE II in these high-risk patients and haemodynamic outcomes were favourable. Heart teams should consider this treatment concept when discussing patients with failed stentless valves or bioroots.
