Fractional flow reserve-guided percutaneous coronary intervention for an intermediate stenosis complicated by a coronary-to-pulmonary artery fistula.
Article in Heart and vessels, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
A 65-year-old man was referred to our hospital following repetitive chest pain. Invasive coronary angiography showed an intermediate stenosis of the proximal left anterior descending artery (LAD), and a coronary fistula originating distal to the stenosis draining into the main pulmonary artery. To evaluate the functional abnormality arising from the stenosis and coronary steal due to the fistula, fractional flow reserve (FFR) was measured using a pressure wire with pullback recording. The FFR value was 0.74 at the distal LAD, 0.78 distal to the fistula, 0.81 proximal to the fistula (distal to the stenosis), and abruptly increased to 1.0 proximal to the stenosis. Based on these FFR results, percutaneous coronary intervention was performed to the stenosis. After stent placement, the FFR value improved to 0.87 at the distal LAD, and no abrupt pressure gradient was observed beyond the fistula and the stent. FFR-guided intervention with pullback pressure recording could be a useful and practical method to apply in cases with coronary stenosis complicated by coronary fistula in the same vessel.
