Validation of Left Ventricular Filling Pressure Evaluation by Order of Tricuspid and Mitral Valve Opening in Patients With Atrial Fibrillation.

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
backgroundAccurate assessment of left ventricular filling pressure in patients with atrial fibrillation or flutter (AF) remains difficult. A novel 2-dimensional scoring system, visually assessing time difference between mitral valve and tricuspid valve opening (VMT) score, based on temporal analysis of early diastolic valve opening, could be applied to these patients. We aimed to determine the usefulness of the VMT score in patients with AF.
methodsWe analyzed 119 consecutive patients with AF who underwent cardiac catheterization as a derivation cohort. The diagnostic performance of the VMT score was further evaluated in an external data set containing 189 patients with AF. Elevated left ventricular filling pressure was defined as a mean pulmonary arterial wedge pressure ≥15 mm Hg. The time sequence of atrioventricular valve opening was visually assessed and scored (0, tricuspid valve first; 1, simultaneous; 2, mitral valve first). When the inferior vena cava was dilated, 1 point was added, and the VMT score was finally graded as 0 to 3. Conventional Doppler parameters to estimate left ventricular filling pressure were also measured.
resultsPulmonary arterial wedge pressure was elevated with an increase in the VMT score (0: 10±3, 1: 13±5, 2: 22±7, 3: 27±6 mm Hg;
conclusionsVMT scoring was a useful echocardiographic marker of elevated left ventricular filling pressure and had an incremental benefit over practical biomarkers in patients with AF.
