Surgical outcomes and follow-up analysis of valvular heart disease combined with left ventricular excessive trabeculation: a retrospective propensity score matching study.

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
objectiveSome patients with valvular heart disease (VHD) also have left ventricular excessive trabeculation (LVET). However, the impact of this myocardial phenotype on perioperative and long-term postoperative outcomes remains unclear. This study was aimed to compare the outcomes of this type patients to those with VHD alone.
methodsA retrospective analysis was conducted on 22 patients diagnosed with VHD and LVET (the VHD+LVET group) and 621 patients diagnosed with VHD alone (the VHD group) at the First Affiliated Hospital of Guangxi Medical University between January 2012 and December 2024. Baseline characteristics- preoperative Pro-B-type natriuretic peptide (Pro-BNP), intraoperative aortic cross-clamp time, left ventricular end-diastolic diameter (LVEDD), European System for Cardiac Operative Risk Evaluation II(EuroSCORE II), etc., were collected. Propensity score matching (PSM) was performed at a 1:3 ratio. patients were followed up until January 31, 2025, with all-cause mortality as the primary endpoint.
resultsBefore matching, significant differences were observed between the two groups in gender, New York Heart Association (NYHA) functional classification, LVEDD, and left ventricular ejection fraction (LVEF) (p < 0.05). After PSM, 22 patients in the case group and 66 patients in the VHD group were matched, with no significant differences in the matched variables (p > 0.05). Both before and after matching, no statistically significant difference in EuroSCORE II scores was observed between the two groups.Postoperative outcomes showed no significant differences between the two groups (p > 0.05). In the case group, the non-compacted to compacted (NC/C) ratio showed significant differences between time points. Survival curves indicated no significant difference between the two groups.
conclusionGiven the small sample size for the LVET-positive subgroup, no statistically significant differences in clinical outcomes were observed between valvular heart disease (VHD) patients with LVET and those without this myocardial phenotype in the present retrospective, propensity-matched cohort. Considering the study limitations, these findings tentatively suggest that VHD patients with LVET may achieve satisfactory surgical outcomes under standardized management.
