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

backgroundRight ventricle-pulmonary artery (RV-PA) conduit stenosis is a relatively uncommon complication after a childhood Ross-Konno procedure. CASE SUMMARY: A man in his 20s presented with progressive dyspnea for 1 year. He had previously undergone modified Konno and Ross-Konno procedures for congenital subaortic stenosis followed by pulmonic balloon valvuloplasty for RV-PA stenosis. Echocardiography demonstrated reduced left ventricular ejection fraction, severe pulmonary hypertension, and right ventricular outflow tract obstruction. Cardiac computed tomography revealed right ventricular outflow/conduit stenosis with calcification. Right heart catheterization showed elevated right ventricular outflow/conduit pressure gradient, confirming severe conduit stenosis. He was referred for surgical pulmonic valve and conduit repair. DISCUSSION: Surgical conduit replacement remains the most definitive treatment strategy in small, calcified conduits. Multimodal imaging strategies aid in comprehensive assessment of anatomy and function of RV-PA conduit and valves to guide intervention strategies in adults with complex congenital heart disease.
