Right Coronary Artery to Left Ventricular Fistula Complicated by Symptomatic Arrhythmia.
Article in Cureus, 2024. 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
Coronary cameral fistulas (CCFs) are rare and are characterized by an abnormal connection between a coronary artery and any of the four chambers of the heart. Most cases of CCFs are asymptomatic. The most common presentation in symptomatic patients includes chest pain or heart failure; however, arrhythmias are rarely associated. We report the case of a 32-year-old male previously unknown to have any medical illnesses. He presented to the clinic with complaints of frequent palpitations, necessitating recurrent admissions. His electrocardiograms revealed regular wide complex tachycardia with a right bundle branch block pattern, suggestive of fascicular ventricular tachycardia. During hospitalization, an elective coronary angiography showed a large CCF originating from the right posterior descending coronary artery and draining into the left ventricle. Moreover, cardiac magnetic resonance imaging did not show any scar or evidence of cardiomyopathies. The patient underwent a successful catheter-based right coronary artery to left ventricular fistula occlusion with coils. In addition, the patient underwent a complex electrophysiological study with three-dimensional mapping and ablation. The presented case underscores the rarity and complexity of such clinical presentations. It also highlights the importance of a multidisciplinary approach in addressing this unique cardiac anomaly.
