Cardiac MRI predictors of right ventricular dysfunction after the Da Silva cone operation for Ebstein's anomaly.
Article in International journal of cardiology. Congenital heart disease, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Introduction: Despite the clinical benefits of the cone operation for Ebstein's anomaly, significant right ventricular (RV) dysfunction is frequently seen immediately after the procedure and if persistent may portend worse long-term outcomes. In this study we sought to evaluate the predictors of RV dysfunction after the cone operation using preoperative CMR. Methods: This was a retrospective review of 26 consecutive patients who had the cone operation. Patients with significant RV dysfunction (RVD), defined as moderate or severe dysfunction by discharge echocardiogram, were compared to patients with no or mild dysfunction (no RVD). Results: The median age at the operation was 12.2 years (interquartile range (IQR): 4.9-31.7 years). Eighteen patients (69%) had RVD. Patients with RVD had worse preoperative RV ejection fraction (36 ± 15 vs 49 ± 11%, p = 0.02) and a larger cardiothoracic (CT) index (44 ± 8 vs 37 ± 6, p = 0.03). The tricuspid valve was more severely abnormal in the RVD group with higher rotational angle (45 ± 17 vs 23 ± 10°, 0.03) and higher displacement index (39 ± 18 vs 23 ± 12%, p = 0.02). RVD associated with a higher vasoactive inotropic score (P < 0.01) and a trend towards a longer intensive care stay (p = 0.07). Conclusion: RVD is common after the cone operation and associated with higher need for postoperative inotropes. Predictors include lower preoperative RV ejection fraction, a more dilated heart and more severe tricuspid valve abnormality. Preoperative CMR is an important tool in preoperative assessment and helps predict RVD.
