Balloon Aortic Valvuloplasty Prior to Self-Expanding TAVI: The BAVSE-TAVI Registry.

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
backgroundDirect transcatheter aortic valve implantation (TAVI) approach is feasible and safe compared to predilatation-TAVI. Certain clinical and computerized tomography (CT)-based characteristics might indicate the need for balloon aortic valvuloplasty (BAV) before TAVI, especially with self-expanding valves.
aimsWe aimed to identify patients who require predilatation before TAVI. METHODS AND
resultsWe performed a retrospective, single-center study between 2020 and 2024, enrolling 315 patients (predilatation = 158 vs. direct = 157) aged 81 ± 6 years, 43.5% male, with EuroSCORE II of 3.7 ± 2.9. The rate of predilatation increased over the study period and was performed more often in patients with higher velocity and pressure gradients on echocardiography, higher aortic valve calcium score on CT, bicuspid morphology, bigger aortic annulus anatomy, severe aortic cusp calcification, tortuous descending aorta (bend > 60°), and horizontal ascending aorta (angle > 50°). Direct implantation was performed more frequently in patients with permanent pacemaker, ischemic heart disease, concomitant significant aortic regurgitation, or alternative-access TAVI. Regression analysis demonstrated that only the horizontal aorta was an independent predictor of predilatation (p = 0.037). The rates of valve recapture, embolization, contrast use, procedure duration, hospital stay, inpatient death, stroke, significant paravalvular leak on postprocedural echocardiography, and new pacemaker implantation were not different between the groups. The rate of BARC ≥ 3 bleeding, mainly due to access-site complications, was more frequent with direct-TAVI compared to predilatation (6.4% vs. 0.6%; p = 0.005).
conclusionsBoth predilatation and direct-TAVI approaches can be safely performed in routine practice. Upfront selection of either approach based on the patient characteristics, echocardiography gradients, and CT anatomical features is recommended.
