Bilateral Modified Self-Expanding Valve Implantation in Branch Pulmonary Arteries.
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
backgroundTranscatheter pulmonary valve implantation (TPVI) in repaired tetralogy of Fallot is challenging due to right ventricular (RV) outflow tract complexity. Severe main pulmonary artery (PA) dilation can preclude TPVI, a platform limitation. CASE SUMMARY: A 67-year-old man with repaired tetralogy of Fallot, severe pulmonary regurgitation, and RV dysfunction presented with right heart failure. Prior institutions deemed him unsuitable for surgical or transcatheter intervention. After multidisciplinary discussion, Harmony valves (Medtronic) were modified by removing distal polyester fabric (rows 1 and 2) to prevent segmental branch PA obstruction, and implanted sequentially in bilateral PAs. RV remodeling and symptom improvement were noted at 3-month follow-up. DISCUSSION: This first reported modified Harmony valve case demonstrates feasibility of bilateral PA implantation without branch obstruction, expanding TPVI options in severely dilated PAs. TAKE-HOME MESSAGE: Modifying the Harmony valve by distal fabric removal preserves segmental PA flow and maintains radial force and valve function in branch PA TPVI.
