Long-term neurological outcomes after transcatheter aortic valve replacement in high-volume cardiovascular care center.
Article in Cardiology journal, 2026. 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
backgroundAortic stenosis (AS) is the most common valvular pathology in Europe and North America, with its prevalence rising due to age-related degeneration and calcification of the aortic valve. The global number of transcatheter aortic valve replacement (TAVR) procedures is rapidly increasing. Nevertheless, the ischemic cerebrovascular events remain among the most significant complications of this procedure. This study aimed to assess the long-term incidence of neurological events and identify the most powerful predictors of stroke following TAVR in a high-volume cardiovascular care center.
methods705 patients who underwent TAVR between January 2016 and September 2022, with a median follow-up of 60 months were analyzed. Baseline patient characteristics, procedural data, and long-term neurological outcomes were evaluated.
resultsAt five years the cumulative incidence of any neurological events, strokes and disabling strokes reached 28.5%, 20.3% and 13.2%, respectively. Periprocedural strokes occurred in 1.4% of patients. The multivariable analysis performed was aimed at identifying the relationship between a range of clinical and procedural variables and the incidence of stroke within five years following TAVR.
conclusionsThe findings highlight the importance of long-term neurological follow-up after TAVR, as stroke mechanisms evolve over time - from periprocedural embolization to thrombus formation or chronic conditions like frailty and atherosclerosis. Future research should focus on more targeted stroke prevention and long-term management strategies enhancing safety for the TAVR recipient population.
