1 · What the graph read from 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.

2 · The registry

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

backgroundTransfemoral venous access is the standard for MitraClip procedures, but anatomic variations can hinder device delivery. CASE SUMMARY: An 88-year-old man with severe mitral regurgitation underwent MitraClip therapy via the right femoral vein. During the procedure, compression by a calcified right iliac artery caused severe tortuosity of the iliac vein, preventing the advancement of the steerable guide catheter. A buddy wire was introduced through a left femoral crossover approach using a Radifocus guidewire into the right iliac vein, allowing successful catheter advancement and device deployment. DISCUSSION: This case highlights the importance of adaptive strategies to overcome anatomic challenges. The buddy wire technique allows for more controlled catheter manipulation and may have reduced the risk of venous injury. TAKE-HOME MESSAGE: The crossover buddy wire technique may be a useful bailout strategy with only minimal additional equipment to facilitate steerable guide catheter delivery in cases of venous compression.
