Comparison of recent clinical effects between right anterior mini- thoracotomy and full sternotomy used in Bentall surgery.
Article in Journal of thoracic disease, 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
Background: The Bentall procedure remains the gold standard for treating aortic root pathologies. However, the conventional full sternotomy (FS) approach is associated with sternal complications and prolonged recovery times. The right anterior mini-thoracotomy (RAMT), a minimally invasive alternative, offers reduced trauma and preserves sternal integrity, but its safety and efficacy require further evaluation. This study aims to compare the short-term outcomes of RAMT and FS in Bentall procedures. Methods: This single-center retrospective study included all patients who underwent Bentall surgery between May 2022 and December 2024. Using a 1:2 matched design to balance baseline characteristics, 16 patients were included in the RAMT group and 32 in the FS group. The primary endpoint was the 30-day incidence of major adverse cardiac and cerebrovascular events (MACCEs). Secondary endpoints included cardiopulmonary bypass time (CPBT), postoperative complications, and short-term follow-up outcomes. Results: The aortic cross-clamp time was significantly longer in the RAMT group compared to the FS group (146±22.4 Conclusions: In patients selected according to strict criteria, the RAMT approach for Bentall surgery was associated with longer aortic cross-clamp time but significantly reduced intraoperative blood loss, while demonstrating comparable perioperative safety and short-term efficacy to the conventional FS approach. RAMT is a feasible minimally invasive option, although its long-term outcomes warrant further validation through larger sample sizes and extended follow-up.
