1 · What the graph read from it

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.

2 · The registry

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

objectiveSpeckle tracking echocardiography (STE) may be a useful modality for assessing ventricular performance in patients with single ventricle physiology. However, STE's ability to accurately assess ventricular performance in this population is unknown. The objective of this study was to perform a preliminary comparison of STE measures of myocardial deformation to reference standard measures of function derived from pressure-volume loop (PVL) analysis.

designThis was a secondary analysis of a prospective study investigating PVLs in patients with Fontan physiology. PVLs were recorded using microconductance catheters. PVL indices included end-systolic elastance (Ees), arterial elastance (Ea), ventriculo-arterial coupling (Ea/Ees), and the isovolumic relaxation time constant (tau). Patients were included if they had an echocardiogram within 1 month of their catheterization. STE was performed retrospectively using vendor independent software.

resultsSeventeen patients had echocardiograms available for analysis, 12 were right ventricular (RV) dominant. The median age was 8 years (IQR 5-17 years). Circumferential strain (r=-.72, P≤.01) and strain rate (r=-.61, P=.04) correlated with Ea/Ees in those with RV-dominant morphology. Longitudinal strain rate correlated with Ees in those with LV-dominant morphology (r=-.98, P≤.01). Longitudinal EDSR correlated with tau in those with LV-dominant morphology (r=-.90, P=.04).

conclusionsIn this limited sample, circumferential measures of deformation correlated with PVL measures better in patients with RV morphology, while longitudinal measures correlated better with PVL measures in patients with LV morphology. Further validation and investigation into the clinical usefulness of these measures are warranted.
