Multicentre experience of sutureless prostheses inside degenerated stentless aortic valves and bioroots.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesPatients 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.
methodsIn 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.
resultsMean 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).
conclusionsRate 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.
