Commissural and coronary alignment of the Venus-A valve after transcatheter aortic valve replacement: a retrospective cross-sectional study.

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: Previous studies have shown that neo-commissural orientation of transcatheter heart valve (THV) can influence coronary obstruction during transcatheter aortic valve replacement (TAVR), long-term durability of THV, and coronary artery access for reintervention after TAVR. Specific initial orientations of Evolut R/Pro and Acurate Neo aortic valves can improve commissural alignment. However, the method of achieving commissural alignment with the Venus-A valve remains unknown. Therefore, this study aimed to evaluate the extent of commissural and coronary alignment of the Venus-A self-expanding valve after TAVR using a standard system delivery technique. Methods: A retrospective cross-sectional study was performed. At the time of enrollment, patients who underwent pre- and post-procedural electrocardiographically-gated contrast-enhanced CT with a second-generation 64-row multidetector scanner were selected for the study. Commissural alignment was categorized as aligned (0-15° angle deviation), mild (15-30°), moderate (30-45°), or severe (45-60°) commissural misalignment (CMA). Coronary alignment was categorized as having no coronary overlap (CO) (>35°), moderate CO (20-35°), or severe CO (≤20°). The results were represented as proportions to assess the extent of commissural and coronary alignment. Results: Forty-five TAVR patients were ultimately included in the analysis. THVs were shown to be randomly implanted: 20.0% of THVs were aligned, 33.3% had mild CMA, 26.7% had moderate CMA, and 20.0% had severe CMA. The incidence of severe CO was 24.4% with the left main coronary artery, 28.9% with the right coronary artery, 6.7% with both coronary arteries, and 46.7% with one or both coronary arteries. Conclusions: The results showed that commissural or coronary alignment could not be achieved with the Venus-A valve using a standard system delivery technique. Therefore, specific methods to attain alignment with the Venus-A valve need to be identified.
