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

backgroundSystemic right ventricular (SRV) cardiomyopathy commonly complicates d-transposition of the great arteries with previous atrial switch repair. Cardiac resynchronization therapy (CRT) is an effective therapy but may be difficult to achieve conventionally via coronary sinus (CS) lead implantation. CASE SUMMARY: A 58-year-old man with a history of d-transposition of the great arteries and prior Mustard procedure presented with progressive dyspnea and QRS duration >200 milliseconds. No suitable CS branch was identified; therefore, we delivered CRT with endocardial SRV lead implantation via a VersaCross radiofrequency wire system. The patient experienced a QRS morphology similar to native conduction and an improvement in his symptoms and cardiac indices. DISCUSSION: Systemic endocardial pacing has previously been demonstrated to be safe and effective in patients with normal cardiac anatomy. TAKE-HOME MESSAGES: Endocardial SRV leads for CRT are effective alternatives to CS lead. The VersaCross system is effective in delivering a transbaffle, SRV lead.
