Systolic Anterior Motion and Dynamic Mitral Regurgitation Following SAVR: A Case of Hemodynamic Optimization Over Intervention.
Article in Echocardiography (Mount Kisco, N.Y.), 2026. 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
Mitral regurgitation (MR) frequently coexists with severe aortic stenosis and may persist or worsen after surgical aortic valve replacement (SAVR) despite afterload reduction. Following SAVR, abrupt ventricular unloading can unmask hyperdynamic ventricular function, promote systolic anterior motion and left ventricular outflow tract (LVOT) obstruction, resulting in dynamic MR and hemodynamic instability. A thorough preoperative assessment of ventricular geometry and mitral valve anatomy is crucial to identify patients at increased risk of post-SAVR LVOT obstruction. We describe a case of severe dynamic MR and LVOT obstruction following SAVR, successfully managed through comprehensive echocardiographic evaluation and tailored hemodynamic optimization, ultimately avoiding unnecessary percutaneous mitral intervention.
