Midterm durability of valve-sparing root replacement in bicuspid and tricuspid aortic valves.

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: Among patients with bicuspid aortic valves (BAV) who are potential candidates for valve-sparing root replacement (VSRR), the long-term durability of this technique is not well understood. This study aimed to compare the clinical and echocardiographic outcomes of VSRR in those with BAV and tricuspid aortic valve (TAV) morphology. Methods: This was a retrospective analysis of patients who underwent VSRR between 2007 and 2021 at a single center. Kaplan-Meier and log-rank analysis were used to estimate and compare freedom from mortality, progression to >2+ aortic insufficiency (AI), and reoperation between groups (BAV vs TAV). Preoperative and postoperative echocardiographic data were collected and assessed for temporal changes in mixed-effect models. Results: A total of 185 patients (BAV, n = 52, 28.1%; TAV, n = 133, 71.9%) underwent VSRR. At baseline, BAV patients were younger (42.4 ± 11.6 vs 52.3 ± 12.6 years; Conclusions: VSRR can be safely performed on patients with BAV and TAV morphology, yielding similar midterm freedom from mortality, recurrent >2+ AI, and reoperation. This technique should be considered in carefully selected patients with aortic root pathology and BAV anatomy when performed at experienced centers.
