Facilitating Tricuspid Edge-to-Edge Repair in Torrential Regurgitation Using Temporary Superior Vena Cava Balloon Occlusion.

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
backgroundTranscatheter edge-to-edge repair (TEER) has emerged as the most widely adopted percutaneous therapy for severe tricuspid regurgitation (TR) in patients at high surgical risk. However, large coaptation gaps and severe leaflet tethering remain major anatomical challenges that may preclude successful leaflet grasping. CASE SUMMARY: We describe 2 patients with torrential TR and large coaptation gaps (15 and 18 mm) who underwent successful tricuspid TEER facilitated by transient superior vena cava (SVC) balloon occlusion. A semicompliant 20-mm valvuloplasty balloon was temporarily inflated within the SVC to reduce venous return and right-sided preload during leaflet grasping. Balloon inflation resulted in marked annular reduction and near-complete elimination of the coaptation gap, enabling successful device implantation and substantial TR reduction in both cases. DISCUSSION: Temporary SVC occlusion may represent a useful adjunctive technique to transiently reduce right-sided preload and tricuspid annular dimensions in challenging anatomies with large coaptation gaps, thereby facilitating successful TEER.
