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

backgroundUntreated aortic stenosis (AS) leads to significant mortality and morbidity. Balloon-expandable Myval transcatheter heart valve (THV) has demonstrated safety and effectiveness for treating severe AS in patients at intermediate or high risk for surgery. This retrospective observational study aimed to analyze the safety and efficacy of Myval THV in AS patients who underwent transcatheter aortic valve implantation (TAVI) at a single-center.

methodsData from 100 consecutive patients who underwent transfemoral TAVI for severe symptomatic AS with Myval THV were analyzed. Baseline characteristics including medical history, clinical features, procedural data, laboratory and echocardiographic data, and outcome data at discharge and 30 days were collected retrospectively. Outcomes as defined according to the consensus document of the Valve Academic Research Consortium-3 were determined.

resultsBaseline characteristics of 100 patients were: 64% males, mean age: 70.87 ± 7.85 years, mean body mass index: 27.97 ± 4.30 Kg/m

conclusionReal-world data on the use of technologically advanced Myval THV leads to safe and precise orthotopic positioning in TAVI patients, ensuring optimal, large effective orifice area, and normal hemodynamic status.
