TAVI with the ACURATE neo2 in severe bicuspid aortic valve stenosis: the Neo2 BAV Registry.
Article in EuroIntervention : journal of EuroPCR in collaboration with the Working Group on Interventional Cardiology of the European Society of Cardiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundThe ACURATE neo2 is a contemporary transcatheter aortic valve implantation (TAVI) system approved for the treatment of severe aortic stenosis in Europe. The ACURATE neo2 has not been evaluated in bicuspid aortic valve (BAV) stenosis.
aimsWe sought to evaluate the safety and efficacy of ACURATE neo2 in patients with BAV stenosis.
methodsWe retrospectively analysed consecutive severe BAV stenosis patients undergoing TAVI with ACURATE neo2 at 10 European centres. Imaging data from preprocedural multislice computed tomography, pre- and postprocedural echocardiography, and procedural cinefluoroscopy were evaluated by a core laboratory. Valve Academic Research Consortium 3 (VARC-3)-defined 30-day procedure safety and efficacy were the primary endpoints. Adverse events were site-reported according to VARC-3 criteria.
resultsAmong 181 patients with BAV stenosis treated with the ACURATE neo2, the mean age was 77.5±7.2 years, 58.0% were female, and the Society of Thoracic Surgeons Predicted Risk of Mortality (STS-PROM) score was 2.3% (1.6-3.7%). Most procedures were transfemoral, and predilatation was performed in all cases. A second valve was required in 4 cases (2.2%). VARC-3-defined technical success was 95.6%. The primary endpoints of device success and early safety occurred in 90.6% and 82.3%, respectively. At 30 days, cardiovascular death occurred in 2.2% (N=4) and stroke in 1.6% (N=3). Core laboratory-adjudicated echocardiography reported an effective orifice area of 2.0 (1.7-2.5) cm
conclusionsThe ACURATE neo2 demonstrated favourable clinical outcomes and bioprosthetic valve performance at 30 days in selected patients with severe BAV stenosis.
