From Repair to Replacement: Ring Detachment and Secondary Annular Injury During Transcatheter Mitral Valve-in-Ring Procedure.

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
objectiveThe present case portrays an infrequent complication of transcatheter mitral valve replacement (TMVR) in a patient with a previous surgical mitral valve repair with ring annuloplasty and an Alfieri stitch, who developed mitral stenosis and heart failure. KEY STEPS: After transseptal puncture, balloon atrial septostomy and mitral balloon valvuloplasty were performed. The transcatheter valve was positioned and deployed through a partial dehiscence on the anterior aspect of the prosthetic ring, probably caused by the balloon valvuloplasty or undetected in the preprocedural imaging assessment. This led to prosthetic ring detachment and dislocation, native annular tearing, migration of the transcatheter prosthesis, and subsequent hemodynamic collapse requiring open surgery. POTENTIAL PITFALLS: In TMVR, prosthesis misalignment or malposition may cause annular stress during deployment and tearing of the native annulus, prosthesis embolization from suboptimal anchoring, and cardiac tamponade from left ventricular rupture, often requiring emergency surgical intervention.
