The influence of different transcatheter aortic valve implantation angles, as assessed by multidetector spiral CT scanning, on the depth of valve implantation and its impact on clinical prognosis.

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
Purpose: This study aimed to investigate the impact of commissural alignment on transcatheter aortic valve implantation (TAVI) depth and clinical outcomes using multidetector spiral computed tomography (MSCT) assessment. Methods: In a retrospective cohort of 215 high-surgical-risk aortic stenosis (AS) patients undergoing TAVI (April 2020-March 2024), patients were stratified into Aligned (0-30° commissural offset, Results: Misaligned patients exhibited lower implantation depths at non-coronary (7.15 ± 0.53 mm vs. 6.95 ± 0.81 mm, Conclusion: Commissural misalignment was associated with deeper valve implantation, higher complication rates, and reduced early quality of life. Precise angular alignment could optimize TAVI outcomes, potentially by improving implantation depth consistency and reducing early adverse events.
