Valve-in-Ring TMVR Following Antegrade Base-to-Tip LAMPOON With ELASTIC on VA-ECMO Support: A Case Report.
Article in Journal of the Society for Cardiovascular Angiography & Interventions, 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
Transcatheter mitral valve replacement (TMVR) in failed surgical rings with an Alfieri stich represents a therapeutic challenge. A 70-year-old man with prior robotic surgical mitral valve repair with an incomplete ring and an Alfieri stich presented with acute decompensated heart failure and was found to have severe mitral regurgitation and pulmonary hypertension. He was deemed not to be suitable for redo surgery. Preprocedural computed tomography demonstrated anterior mitral leaflet length of 29 mm, indicative of high-risk for dynamic left ventricular outflow tract obstruction. This case described the successful combination of antegrade laceration of the anterior mitral valve leaflet to prevent outflow obstruction and electrosurgical laceration of Alfieri stitch to facilitate valve-in-ring TMVR while on venoarterial extracorporeal membrane oxygenation support to prevent hemodynamic compromise during high-risk valve-in-ring TMVR.
