Comparative study of transcatheter aortic valve implantation versus conventional surgical aortic valve replacement in the treatment of severe aortic stenosis with reverse ventricular remodeling.

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
Introduction: This study aimed to compare echocardiographic outcomes and analyze the changes in ventricular remodeling at different time points after surgery in patients with severe aortic stenosis (AS) undergoing either surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). Methods: This retrospective study consecutively enrolled 175 patients with severe AS who underwent either SAVR or TAVR. Transthoracic echocardiograms obtained at baseline, 30 days, and 1 year after the procedure were analyzed by multiple echocardiographers at our institution. Results: At baseline, the TAVR group was significantly older (74 ± 7 years vs. 62 ± 9 years, Conclusion: In patients with severe aortic stenosis, SAVR was associated with more significant regression of left ventricular dimensions and mass at 1 month compared to TAVR, alongside a transient impairment of right ventricular function. By 1 year postoperatively, however, no significant differences in ventricular remodeling were observed between the two groups.
