Haemodynamic Early Outcomes of Sinus Plication for Bicuspid Aortic Valve Repair.
Article in Interdisciplinary cardiovascular and thoracic surgery, 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
objectivesPostoperative stenosis negatively affects durability after bicuspid aortic valve (BAV) valvuloplasty. This study was performed to evaluate the haemodynamic efficacy of sinus plication (SP) to avoid stenosis after asymmetrical BAV repair.
methodsBetween 2018 and 2023, 41 patients with BAV (33.3 ± 11.5 years, 40 males) with moderate-severe aortic regurgitation (AR) underwent aortic valve repair with (SP group, n = 14) or without (NSP group, n = 27) SP. SP was performed to reduce the circumference of the fused sinus and restore sinus contour symmetry. Preoperative and postoperative haemodynamic parameters were assessed at discharge and 1 year using transthoracic echocardiography.
resultsNo deaths occurred within 1 year after surgery in either group. AR was well controlled and adequate left ventricular reverse remodelling was observed in both the groups up to 1 year postoperatively. At 1 year, lower transvalvular peak pressure gradient (PG) and maximum transvalvular flow velocity (Vmax) were observed in the SP group (peak PG: 17.7 ± 5.5 mmHg; % change -8.8% ± 1.1%, Vmax: 1.9 ± 0.31 m/s; % change -13.1% ± 2.1%) compared with the NSP group (peak PG: 24.7 ± 9.6 mmHg; +8.8% ± 1.3%, Vmax: 2.58 ± 0.62 m/s; +9.3% ± 2.5%), while there were no clear differences in % changes of peak PG or Vmax between the groups after adjustment for covariates.
conclusionsIn BAV repair, SP was potentially associated with lower peak PG and Vmax at 1 year. These findings suggest that SP may enhance haemodynamic stability in BAV repair.
