Immediate change following valve deployment in left ventricular systolic and diastolic functions in transcatheter aortic valve replacement: a retrospective cohort 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: Transcatheter aortic valve replacement (TAVR) is an effective treatment for aortic valve disorder. Several studies have reported improvements in systolic and diastolic function following TAVR. However, few studies have addressed immediate post-deployment changes. Therefore, this study examines left ventricular (LV) systolic and diastolic function changes immediately after valve deployment in TAVR patients, distinguishing between those with normal and impaired LV ejection fraction (LVEF). Methods: In this single-center retrospective cohort study, intraoperative changes in LV systolic and diastolic function were analyzed in patients undergoing TAVR from January 2012 to September 2014. Participants were categorized into two groups based on preprocedural LVEF: the low ejection fraction (EF) group (LVEF <50%) and the normal EF group (LVEF ≥50%). LVEF, as an indicator of LV systolic function, along with lateral e' and the E/e' ratio as indicators of LV diastolic function before and immediately after valve deployment were compared in the overall cohort and within each group. Results: Forty-eight TAVR cases were included, comprising 15 in the low EF group and 33 in the normal EF group. Overall, there was a significant improvement in LVEF {51.7% [standard deviation (SD)] 15.0 Conclusions: This study revealed significant intraoperative improvements in systolic and diastolic functions immediately after valve deployment in TAVR patients with low preprocedural LVEF. These immediate improvements were not observed in patients with normal LVEF.
