A Rare Case of Single Coronary Artery With Pulmonary Artery Fistula.

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
backgroundSingle coronary artery is a rare congenital anomaly. Its coexistence with coronary artery fistula is exceedingly uncommon. CASE SUMMARY: A 61-year-old woman with no cardiovascular risk factors underwent her first cardiological evaluation after incidental detection of atrial fibrillation. Imaging revealed a markedly dilated single coronary artery originating from the left coronary sinus, with a large fistula to the pulmonary artery trunk. Despite atrial enlargement and moderate mitral and tricuspid regurgitation, the patient was asymptomatic with preserved ventricular function. A conservative management strategy with close follow-up was adopted after multidisciplinary discussion. DISCUSSION: Management of rare coronary anomalies should be individualized. While surgery is recommended in symptomatic patients or those with evidence of ischemia, asymptomatic individuals may be managed conservatively; however, signs of adverse cardiac remodeling should prompt early reconsideration of intervention. TAKE-HOME MESSAGE: Conservative follow-up may be appropriate in asymptomatic patients with complex coronary anomalies, but progressive structural changes warrant timely reassessment of surgical options.
