Refractory ventricular fibrillation caused by coronary insufficiency after Bentall procedure: A case report.
Article in World journal of clinical cases, 2025. 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
backgroundIn open heart surgery requiring cardiopulmonary bypass (CPB), ventricular fibrillation (VF) is common, but refractory recurrent VF is uncommon but perilous. CASE SUMMARY: This article reports a 58-year-old male patient with an ascending aortic aneurysm who presented for a Bentall procedure and subsequently experienced multiple occurrences of unexplained VF after weaning from CPB. The recurrent episodes of VF in this case were felt to be related to coronary insufficiency after reconstruction of the aortic root. Coronary artery bypass grafting (CABG) of the proximal right coronary artery and the left anterior descending artery successfully resolved VF. Finally, this patient was safely transferred to the postoperative intensive care unit, and was discharged successfully after subsequent supportive treatment.
conclusionIn aortic root replacement, coronary insufficiency is a potential cause of VF episodes and should be considered in the differential diagnosis. CABG is the sole effective treatment for VF caused by coronary insufficiency.
