Percutaneous Closure of an Atrioventricular Groove Rupture Causing a Left Atrial Dissection After Cardiac Surgery.

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
backgroundLeft atrial dissection (LatD) is a rare and life-threatening complication of mitral valve surgery. CASE SUMMARY: A 60-year-old woman underwent mitral valve replacement for severe mitral regurgitation. Intraoperative transesophageal echocardiography revealed a LatD caused by a covered atrioventricular (AV) groove rupture, with systolic flow from the left ventricle into an atrial false lumen (FL). Moreover, an interatrial septal fenestration, connected the FL with the right atrium. Despite initial hemodynamic stability, multimodality imaging demonstrated a progressive enlargement of the FL. Given the prohibitive surgical risk, a fully percutaneous transaortic closure of the AV groove rupture was successfully performed using a ventricular septal defect occluder, followed by closure of the interatrial septal fenestration. DISCUSSION: Heart team decision making and multimodality imaging are fundamental in managing LatD. TAKE-HOME MESSAGE: Percutaneous transaortic closure may represent a lifesaving alternative to redo surgery in selected cases of AV groove rupture complicated by LatD.
