Surgical Explant of Degenerated Transcatheter Valves: A New Type of Threat?
Review in Interdisciplinary cardiovascular and thoracic surgery, 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
objectivesTranscatheter treatment for valvular heart diseases has markedly expanded its indications due to reduced invasiveness and hospitalization time. Despite favourable results, several peculiar and more frequent shortcomings than occur with a surgical-based implant have been reported. This review provides the currently available information regarding a transcatheter heart valve (THV) implant and reoperation, focusing on recent available data about surgical management strategies for THV degeneration.
methodsFor this narrative review, we searched Medline through the end of March 2025 using medical subject headings and text words supplemented by scanning the bibliographies of recovered articles. The terms "transcatheter valve degeneration," "TAVI degeneration," "surgical treatment," and "surgical explant" have been combined using the Boolean operator "AND".
resultsCurrently available articles focus specifically on the aortic THV explant. Peculiar intraoperative (like coronary ostium, aortic wall and annular injury due to THV explant) or short-term postoperative complications related to THV explant have been reported. Thirty-day mortality has been shown to range between 12% and 32.6%, and only short and heterogeneous follow-up periods are available to date. A careful work-up to indicate that the valve-in-valve procedure is not feasible or not appropriate when facing degenerated THV and a cautious, detailed plan of the surgical explant have been recently recommended.
conclusionsTHV explants due to valve degeneration are rapidly increasing, but, due to the related risk for intra- and post-procedural complications, careful preoperative evaluation and intraoperative handling are warranted.
