Surgical Approach to the Management of a Large Right Coronary Artery Aneurysm and Coronary Sinus Fistula.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 fistulas (CAF) are rare anomalous communications between a coronary artery and a second cardiovascular structure that can have marked physiological impact. CASE SUMMARY: A 66-year-old woman presented with progressive dyspnea and was found to have an ectatic arteriovenous fistula of the right coronary artery to the coronary sinus with resultant diffuse aneurysmal right coronary artery dilatation. She underwent fistula ligation and a triple aorto-greater saphenous vein bypass to the sinus node artery, right ventricular branch, and right posterior descending artery. Her postoperative course was complicated by ventricular fibrillation arrest and persistent moderate right ventricular systolic dysfunction. DISCUSSION: Hemodynamically significant CAF require surgical intervention. Principles of repair involve fistula ligation, exclusion of any aneurysmal segments, and myocardial revascularization. TAKE-HOME MESSAGES: CAF can present as worsening left-to-right shunts with symptoms of progressive cardiomyopathy or myocardial steal necessitating complex surgical repair. Perioperative myocardial infarction remains a serious complication.
