Impact of aortic root surgery during transcatheter aortic valve explant.
Article in JTCVS structural and endovascular, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Transcatheter aortic valve replacement (TAVR) explantation is currently the fastest-growing cardiac surgery procedure. Issues surrounding TAVR explantation and subsequent surgical aortic valve replacement (SAVR), specifically aortic root surgery, merit further investigation. Methods: A retrospective review of an institutional database identified cases of SAVR after TAVR, with or without concomitant aortic root operations, performed between January 1, 2014, and July 1, 2023, identifying 26 patients. Conventional statistical methods were used to compare groups. Results: The mean Society of Thoracic Surgeons predicted risk of mortality for aortic valve replacement was 11.1 ± 6.0% in our cohort. Eight of 26 patients (30.8%) had undergone prior cardiac surgery. Concomitant aortic root enlargement or replacement was required in 12 of the 26 patients (46.2%). The time from TAVR to removal was longer for those requiring root operations compared to those who did not (mean, 783 ± 908 days vs 492 ± 486 days; Conclusions: TAVR explant remains a high-risk procedure, although adding aortic root enlargement/replacement does not appear to amplify the short-term mortality risk when performed at an experienced institution. These results are important when considering lifetime management of aortic stenosis, particularly in low-risk patients likely to require multiple interventions.
