Transapical Transcatheter Aortic Valve Implantation with the J-Valve System in Aortic Regurgitation.
Article in CJC open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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: Aortic regurgitation (AR) is a condition associated with significant morbidity and mortality, particularly in severe cases. The J-Valve system, next-generation transcatheter heart valve, may overcome the procedural challenges associated with treating pure AR. This study reported the outcome of use of the J-Valve for treatment of AR. Methods: This study observed 47 patients undergoing transcatheter aortic valve implantation (TAVI) with the J-Valve system. Diagnostic evaluation included transthoracic echocardiography and multislice computed tomography to assess AR severity and anatomic characteristics essential for TAVI. Follow-up evaluations were conducted at various intervals postoperation to evaluate outcomes. Results: The patients had a mean age of 73.0 ± 9.0 years and a median ejection fraction of 58.0% (interquartile range, 45.0%-64.0%). The median European System for Cardiac Operative Risk Evaluation (EuroSCORE II) was 3.0% (interquartile range, 2.0%-6.7%). The procedural success rate was 100%, with no need for a second valve implantation or conversion to sternotomy. Short-term outcomes showed significant improvements in the New York Heart Association functional classification ( Conclusions: TAVI with the J-Valve system presents a viable alternative for managing severe AR, demonstrating high procedural success and substantial clinical improvement. However, the case of valve migration due to Behçet's disease highlights the need for careful preoperative screening and consideration of autoimmune disorders in differential diagnoses.
