Transcatheter Mitral Valve-in-Valve Replacement With Balloon-Assisted Translocation in Calcified Mitral Anterior Leaflet.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 2 of them syntheses that pooled it.
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
objectiveA significant anatomical limitation of transcatheter mitral valve replacement (TMVR) is the risk of left ventricular outflow tract obstruction. Here, we describe balloon-assisted translocation in mitral anterior leaflet (BATMAN) in a patient with a calcified bioprosthetic mitral valve. KEY STEPS: The anterior mitral leaflet is traversed with a 0.014-inch stiff wire with electrocautery, followed by the delivery of a long sheath and placement of dual wires. The dual-wire system allows for BATMAN, followed by a rapid delivery of the transcatheter heart valve, minimizing exposure to significant mitral regurgitation. POTENTIAL PITFALLS: Leaflet traversal with a 0.035-inch system may be difficult because of leaflet calcification, and translocation of the anterior mitral leaflet without dual wires in place potentially exposes the patient to intraprocedural hemodynamic compromise. TAKE-HOME MESSAGES: Transcatheter mitral valve replacement with BATMAN in calcified leaflets may be facilitated by lower-profile crossing wires. Placement of dual wires for rapid exchange following BATMAN may reduce the risk of hemodynamic consequences.
