Massive Tricuspid Regurgitation After Implantable Cardioverter Defibrillator Lead Extraction: A Late Complication From Ghost Material.
Article in JACC. Case reports, 2025. 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
backgroundModerate tricuspid regurgitation (TR) is seen as pathological and can result from atrial or ventricular dilatation or interaction with device leads. Rarely, fibrotic remnants after transvenous lead extraction (TLE), referred to as "ghost material", can impair tricuspid valve function. CASE SUMMARY: A 64-year-old woman presented with dyspnea and fatigue. Echocardiography revealed massive primary TR, with a flail-like appearance of the posterior leaflet caused by a linear mobile structure retracting the leaflet. During surgery, the structure was identified as remnant fibrotic material of previous TLE, causing progressive massive TR in the course of 20 years. DISCUSSION: After TLE, residual fibrotic remnants, referred to as "ghost material", when attached to the valve apparatus can lead to progressive TR, even after many years. TAKE-HOME MESSAGE: Long-term outpatient follow-up is essential after TLE, as TR may progress and "ghost material" may even further induce fibrosis on the valve apparatus.
