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

backgroundThe therapeutic management of patients with multivessel disease and severe left ventricular dysfunction is complex and controversial.

aimsThe aim of this study was to analyze the clinical outcomes and the changes in left ventricular ejection fraction (LVEF) in patients with severe left ventricular dysfunction and at least one chronic total occlusion (CTO) undergoing percutaneous coronary intervention (PCI) with hemodynamic support provided by Impella.

methodsRetrospective, multicenter study enrolling patients with severe left ventricular dysfunction and severe coronary artery disease with at least one CTO who required percutaneous mechanical circulatory support with Impella, from January 2019 to December 2023. The primary endpoints were the incidence of MACE (composite of cardiovascular death, acute myocardial infarct, and target lesion revascularization) at 90 days. The secondary endpoint was changes in LVEF and functional class during the same period.

resultsA total of 27 patients (34 CTOs) were included in the study. The mean SYNTAX score was 35 ± 11. The median J-CTO score of 2 (1-3). At 90 day of follow-up, there were three MACE (11%), two cardiovascular deaths and one TLR; three vascular complications were related to access for the Impella device (only one required invasive treatment); and LVEF improved significantly after revascularization (delta LVEF: 10% [CI 95% 6, 15]). A total of 81% of patients improved their angina or dyspnea status at 90 days.

conclusionsIn high-risk patients with severe left ventricular dysfunction with complex coronary disease including CTO, PCI with mechanical circulatory support using the Impella device is associated with favorable safety and efficacy outcomes at short-term follow-up.
