Prosthetic Aortic Valve Migration Into the Left Ventricular Outflow Tract in Takayasu Arteritis.

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
backgroundProsthetic valve-related complications are well recognized in Takayasu arteritis (TAK). However, migration of a prosthetic aortic valve into the left ventricular outflow tract (LVOT) is exceedingly rare. CASE SUMMARY: We report 2 patients with TAK who experienced downward migration of the aortic prosthetic valve into the LVOT after aortic valve replacement, without any evident paravalvular leak. In patient 2, progressive valve migration led to mechanical interference with the anterior mitral leaflet, resulting in hemodynamics similar to those of mitral stenosis. In both cases, valve migration advanced over time and ultimately necessitated double valve replacement. The underlying mechanism for this phenomenon could not be determined, and histopathological confirmation was not feasible because of insufficient tissue sampling.
conclusionsProsthetic valve migration into the LVOT represents a rare but clinically significant form of valve dysfunction in TAK, which may progress without overt regurgitation and necessitate complex reoperative valve surgery.
