Rare Right Atrial Thrombus Deferred Atrial Septal Defect Closure and Implantable Cardioverter-Defibrillator Placement.

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
A 47-year-old man with nonischemic cardiomyopathy and atrial septal defect (ASD) was scheduled for percutaneous ASD closure and to be followed by implantable cardioverter-defibrillator placement. Preprocedural transesophageal echocardiography unexpectedly revealed a large right atrial thrombus, leading to cancellation of both procedures. The patient was managed conservatively with warfarin. This case illustrates the rarity of right atrial thrombus in patients without atrial arrhythmia or indwelling devices and emphasizes the critical role of preprocedural imaging in preventing potential embolic complications. To our knowledge, this is the first reported case of a right atrial thrombus detected during ASD closure.
