Evolving Redo Frame-Preserving Leaflet Resection: From Transcatheter to Surgical Aortic Valves.
Article in Annals of thoracic surgery short reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Redo aortic valve replacement after bioprostheses failure carries high risk from friable tissue, pannus ingrowth, and potential root reconstruction. Building on the Surgical Resection of Prosthetic Valve Leaflets Under Direct Vision (SURPLUS) technique for failed transcatheter valves, we describe a novel evolution for failed surgical bioprostheses: Surgical Valve Preservation and Resection of Bioprosthetic Leaflets (SUPERB). In SUPERB, degenerated leaflets are excised while the supporting ring is preserved, permitting deployment of a balloon-expandable prosthesis under direct vision. Methods: Between January 2023 and August 2025, 3 high-risk patients with degenerated aortic valves underwent redo replacement at a tertiary center: 2 with failed surgical bioprostheses (SUPERB) and 1 with a failed transcatheter prosthesis (SURPLUS). All were unsuitable for valve-in-valve transcatheter replacement due to low coronary heights, pannus ingrowth, or small annuli. Operative details, perioperative course, and follow-up echocardiography were reviewed. Results: All patients underwent successful leaflet excision with balloon-expandable valve deployment and confirmed coronary patency. Cross-clamp and cardiopulmonary bypass times were minimized vs conventional explantation, and no annular disruption or root replacement was required. Postoperative complications included transient acute kidney injury (n = 2), delirium (n = 1), hypotension (n = 1), and urinary retention (n = 1). All were discharged to rehabilitation. At follow-up, the prostheses remained functional with preserved ventricular performance and no valvular regurgitation. Conclusions: The SUPERB technique extends the SURPLUS concept to failed surgical bioprostheses, providing hybrid alternatives to complete prosthesis explantation. These strategies may reduce operative risk by shortening cross-clamp and bypass times, preserving coronary access, and avoiding root reconstruction. Multicenter evaluation is warranted.
