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: Management of isolated tricuspid valve surgery has evolved over recent decades with respect to operative timing, surgical strategy, and perioperative care. However, a contemporary synthesis of North American outcomes and practice patterns is lacking. Methods: We performed a systematic review and meta-analysis of studies published between January 1, 2020, and August 30, 2025, reporting outcomes of isolated tricuspid valve surgery in North America. Outcomes assessed included operative mortality, temporal volume trends, repair Results: Twelve studies met the inclusion criteria. Operative mortality ranged from 5% to 8% in national cohorts and was approximately 2% at reference centers, with a declining trend over time. Mortality was lower among endocarditis patients as well as patients with better functional status and normal right ventricular function. Procedure volumes peaked around 2017 and have since plateaued or modestly declined, coinciding with increased use of transcatheter therapies. At Mount Sinai Hospital, 107 patients underwent isolated tricuspid valve surgery since 2014; 46% were reoperations, 54% were performed on a beating heart, 34% underwent repair, and in-hospital mortality was 1.9%. In the pooled meta-analysis of contemporary North American studies, operative mortality following isolated tricuspid valve surgery was 6.4% [95% confidence interval (CI): 4.9-8.3%], with significantly lower mortality observed with tricuspid valve repair (TVr) compared with tricuspid valve replacement (TVR) [odds ratio (OR) =0.74; 95% CI: 0.58-0.95]. In addition, pooled meta-analysis showed that TVr was associated with a significantly reduced risk of new permanent pacemaker (PPM) implantation (OR =0.39; 95% CI: 0.32-0.47). Conclusions: Isolated tricuspid valve surgery is increasingly safe, especially among high-volume centers and carefully selected patients. Annual case volumes seem to have plateaued, likely due to the growing application of transcatheter therapies.
