Correlation of Invasive Left Atrial Pressure and Mitral Valve Area in Rheumatic Mitral Stenosis: A Cross-Sectional Study.
Article in Research in heart yield and translational medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Highlights: Mean left atrial pressure (LAP) measured invasively correlates with mitral valve area (MVA) assessed by 3D-TEE in patients with severe rheumatic mitral stenosis.Patients with MVA<1 cm Background: Mitral stenosis (MS) is typically assessed using both echocardiographic and invasive methods, which are critical for treatment planning. The present study analyzed the correlation between invasively measured left atrial pressure (LAP) and mitral valve area (MVA) assessed by three-dimensional transesophageal echocardiography (3D-TEE) in patients with rheumatic MS undergoing percutaneous transluminal mitral commissurotomy (PTMC). Methods: We conducted a cross-sectional study of 135 patients with severe rheumatic MS who were candidates for PTMC at Shahid Madani Heart Hospital, Tabriz, Iran, between April 2023 and April 2024. All patients underwent two-dimensional transthoracic echocardiography (2DTTE) and 3D-TEE for MVA measurement. Invasive LAP and pulmonary pressures were recorded pre-procedure. Comparisons were made between patients with MVA<1 cm Results: The mean MVA measured by 3D-TEE was 1.03±0.07 cm Conclusions: In this study, we observed a significant correlation between invasive LAP and MVA measured by 3D-TEE. These findings suggest that invasive LAP measurement offers additional value in assessing the hemodynamic burden of severe MS.
