Bilateral Coronary Artery-to-Pulmonary Artery Fistula Treated Using Minimally Invasive Coils and Vascular Embolization Devices.

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
backgroundCoronary artery-to-pulmonary artery fistula (CAPF) is a rare condition that is often asymptomatic; however, intervention is indicated in symptomatic patients or in those with myocardial ischemia. CASE SUMMARY: A 44-year-old woman with a cardiac murmur since early adulthood presented with progressive exertional dyspnea. Cardiac computed tomography revealed bilateral plexus-like CAPF with aneurysmal formation. Although the Qp/Qs ratio was 1.08, stress cardiac magnetic resonance imaging demonstrated myocardial ischemia. Pulmonary artery-side outflow embolization was performed using a vascular occlusion device, followed by coil embolization of the coronary artery-side inflow sites, resulting in resolution of symptoms and improvement of ischemia. DISCUSSION: Although pulmonary artery-side embolization can be effective when fistulous drainage converges into a single site, intercommunication between bilateral fistulas may elicit to-and-fro flow and compromise coronary perfusion. TAKE-HOME MESSAGE: In plexus-like CAPFs with intercommunication, combined pulmonary artery outflow and coronary artery inflow embolization should be considered according to vascular morphology.
