Incidence, Predictors, and Prognostic Impact of Left Ventricular Outflow Tract Obstruction Following Transcatheter Aortic Valve Replacement.
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 2 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: Dynamic left ventricular outflow tract obstruction (LVOTO) following transcatheter aortic valve replacement (TAVR) is a potential complication that can cause severe hemodynamic instability. However, limited evidence is available regarding the incidence and predictors of LVOTO post-TAVR. This study aimed to clarify the incidence and identify the predictors of LVOTO following TAVR and to investigate whether LVOTO is associated with clinical outcomes. Methods: This retrospective, single-centre study analyzed 2068 consecutive patients with aortic stenosis who underwent TAVR between January 2014 and December 2023. Transthoracic echocardiography was performed both before and after TAVR. LVOTO was defined as a peak pressure gradient exceeding 30 mm Hg. Results: LVOTO occurred in 25 of 1963 patients (1.3%), with 6 patients developing acute hemodynamic compromise immediately after TAVR. Least absolute shrinkage and selection operator-penalized regression analysis identified the left ventricular outflow tract dimension (LVOTD), interventricular septum (IVS) thickness, transvalvular velocity, LVOT maximum velocity (V Conclusions: The incidence of LVOTO after TAVR was 1.27%. Predictors of LVOTO were the IVS thickness, transvalvular velocity, LVOTD, LVOT V
