DragonFly™ edge-to-edge repair of the systemic atrioventricular valve in a patient with congenitally corrected transposition of the great arteries: a case report.

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
Background: Congenitally corrected transposition of the great arteries (ccTGA) features atrioventricular and ventriculo-arterial discordance. A substantial proportion of patients with ccTGA develop systemic right ventricular dysfunction and overload, leading to functional systemic atrioventricular valve (SAVV) regurgitation that markedly worsens clinical outcomes. Isolated SAVV interventions, specifically transcatheter edge-to-edge repair (TEER), have been scarcely reported. Case summary: An 84-year-old man with ccTGA was referred for treatment of severe systemic atrioventricular valve regurgitation. The patient had a history of atrial fibrillation and presented with progressive heart failure symptoms despite optimal guideline-directed medical therapy (GDMT). Owing to advanced age, multiple comorbidities, and a prohibitive surgical risk, the multidisciplinary Heart Team opted for transcatheter edge-to-edge repair using the DragonFly Discussion: Our case demonstrates that transcatheter edge-to-edge repair using the DragonFly™ system may represent a feasible alternative for selected patients with ccTGA and functional systemic atrioventricular valve regurgitation who are at prohibitive surgical risk. Careful patient selection and meticulous procedural planning based on multimodality imaging are essential to achieve optimal outcomes in this complex population.
