Worsening Mitral Stenosis Due to Post-transcatheter Aortic Valve Replacement Improvement of Concomitant Aortic Insufficiency.
Article in Cureus, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Transcatheter aortic valve replacement (TAVR) has become an alternative to surgical treatment in severe aortic valve stenosis, with expanding indications and rapidly growing number of performed procedures. Poor opposition of TAVR prosthesis to the aortic root causes paravalvular leak, while mitral regurgitation and stenosis have been associated with valve implantation low in the left ventricular outflow tract (LVOT). We report an unusual case of a patient with combined severe aortic stenosis and moderate aortic insufficiency who underwent elective TAVR, which resulted in significant increase of a pre-existing mitral valve gradient. Rapid post-TAVR increase in mitral valve gradient was likely due to improvement in aortic regurgitation and decreased left ventricular end-diastolic pressure (LVEDP).
