Routine versus selective use of a femoral protection wire in transfemoral TAVI: a single-centre analysis of vascular complications.

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
backgroundTransfemoral transcatheter aortic valve implantation (TAVI) is the treatment of choice for severe aortic stenosis in patients with elevated surgical risk. However, vascular complications remain a major source of morbidity and mortality. The protection wire technique was introduced to prevent major access-related complications, but its role in contemporary TAVI practice is uncertain.
aimsTo evaluate whether routine protection wire use reduces vascular complications in contemporary transfemoral TAVI.
methodsWe performed a retrospective, single-centre analysis of 1476 consecutive patients undergoing transfemoral TAVI between January 2020 and August 2023. Until November 2021, protection wire placement was standard-of-care (Group 1, n = 801); thereafter procedures were performed without routine protection wire use (Group 2, n = 675). Vascular complications were defined according to VARC-3 criteria. Multivariable logistic regression was used to identify independent predictors of minor and major vascular complications.
resultsThe composite of minor and major vascular complications occurred more frequently in Group 1 than in Group 2 (18.6% vs. 10.8%, p < 0.001). In Group 1, 34.8% of access-related complications were associated with the protection wire access. Major vascular complications were numerically less frequent in Group 2 (2.5% vs. 4.2%). Omission of routine protection wire placement was independently associated with a lower risk (OR 0.52, 95% CI 0.38-0.72, p < 0.001).
conclusionIn contemporary transfemoral TAVI, routine protection wire use was not associated with reduced major vascular complications and was linked to a higher rate of minor access site injuries. These findings support a restrictive rather than routine use of protection wires in current practice.
