Pulmonary Artery Denervation With Transcatheter Tricuspid Valve Replacement for Severe Tricuspid Regurgitation and Pulmonary Hypertension.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPulmonary hypertension (PH) and severe tricuspid regurgitation (TR) are often comorbid, with negative prognostic implications. We hypothesized that sequential pulmonary artery denervation (PADN) and transcatheter tricuspid valve replacement (TTVR) could be a one-stop solution to optimize surgical results for such high-risk patients. CASE SUMMARY: A very high-risk patient with systemic lupus erythematosus who had severe TR and mixed PH was successfully treated with PADN and TTVR in a single sequential operation. DISCUSSION: Both pulmonary artery pressure and right ventricular (RV) function are predictors of outcomes after both open surgical and transcatheter tricuspid repair or TTVR. We describe a novel, safe technique to immediately reduce the pulmonary artery systolic pressure in a patient with PH and severe TR; this is to our knowledge the first report of such a completely percutaneous, combined operation in the literature. TAKE-HOME MESSAGE: Preoperative PADN may be a safe and effective way to reduce pulmonary artery pressures and mitigate the risk of postoperative acute RV failure due to RV afterload mismatch in patients with PH and severe TR.
