BATMAN-Assisted Valve-in-Valve TMVR With Planned Hemodynamic Support in Severe Pulmonary Hypertension.
Article in JACC. Case reports, 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
backgroundLeft ventricular outflow tract (LVOT) obstruction is a feared complication of transcatheter mitral valve replacement (TMVR), and balloon-assisted translocation of the mitral anterior leaflet (BATMAN) has emerged as a mitigation strategy. Patients with severe pulmonary hypertension are at risk, as abrupt elimination of mitral regurgitation (MR) can destabilize hemodynamics. CASE SUMMARY: A 78-year-old woman with a degenerated 25-mm surgical bioprosthesis, severe pulmonary hypertension (mean pulmonary artery pressure 65 mm Hg), and reduced cardiac index (1.9 L/min/m DISCUSSION: BATMAN enabled successful TMVR despite high-risk anatomy. Prophylactic IABP facilitated hemodynamic stability during the transition from chronic MR physiology. This is among the first reports combining planned mechanical circulatory support with BATMAN-assisted TMVR in severe pulmonary hypertension. TAKE-HOME MESSAGE: BATMAN-assisted valve-in-valve TMVR with planned IABP support may facilitate safe treatment of selected patients with severe pulmonary hypertension and predicted LVOT obstruction.
