Percutaneous Management of Recurrent Postsurgical Right Atrial Cicatricial Stenosis Causing Supratricuspid Obstruction.

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
backgroundPostsurgical right atrial cicatricial stenosis is a rare iatrogenic complication following extensive atrial reconstruction. When located above the tricuspid valve, this fibrotic tissue may cause supratricuspid obstruction, producing symptoms and hemodynamic findings similar to tricuspid stenosis. CASE SUMMARY: A 41-year-old man with a history of complex atrial reconstruction using bovine pericardium and a Dacron graft presented with progressive dyspnea 1 year postoperatively. Echocardiography revealed a cicatricial supratricuspid membrane with a peak gradient of 18 mm Hg. Percutaneous balloon dilation was performed with immediate hemodynamic improvement; however, obstruction recurred 3 times at intervals of 8, 6, and 6 months, each successfully managed with repeat dilation. DISCUSSION: Given the prohibitive surgical risk conferred by 2 prior complex sternotomies, prosthetic atrial reconstruction, and significant systemic comorbidities, as determined by multidisciplinary Heart Team consensus, a percutaneous strategy was adopted. Each intervention achieved gradient reduction; however, fibrotic remodeling of the cicatricial tissue led to recurrent obstruction over time.
