Right ventricular structure and function after novel repair of common arterial trunk.

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
Objectives: In an attempt to enhance applicability and outcomes of corrections of common arterial trunk, we have recently described a novel method of correction based on the concept of morphodynamism, and preserving the structure of the right ventricle. The intermediate influence of this operation on right ventricular (RV) structure and function have not been described. Methods and results: Thirty eight Patients (age: 1-12 months) underwent the novel repair. There were 2 early and 4 late deaths. All patients underwent early CT scans, 12 had repeat CT and 8 had MRI after 1 year or more from the operation. Detailed computerized analysis of the RV size, shape, pattern of contraction and function was performed. The shape and size were preserved, at the second investigation, with no evidence of dilatation of the neo-RV outflow, which appeared to contribute to overall function of the RV. The directional pattern of contraction showed enhanced longitudinal and radial contributions with minimal twisting. The movement of the RV free wall and septum were almost equal, with normal shape of the septum. The instantaneous pattern of contraction followed a consistent peristalsis sequence with significant contraction of both the body and the neo-outflow. The pulmonary regurgitant fraction, at follow up, varied from 22% to 42% (30 ± 6%) with preserved RV to pulmonary artery ventriculo-arterial coupling. Conclusion: The size, shape and pattern of contraction of the RV following the novel common arterial trunk repair appears to be well preserved in the intermediate term.
