Transhepatic Access for Pulsed Field Ablation of Atrial Fibrillation Using a Dual-Energy Lattice-Tip Catheter.
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
backgroundIn patients with interrupted inferior vena cava (IVC) requiring atrial fibrillation (AF) ablation, transhepatic access is an established alternative to femoral venous access. Prior reports have described AF ablation using radiofrequency platforms, but, to our knowledge, transhepatic AF ablation with a dual-energy lattice-tip catheter integrating high-density mapping, pulsed field ablation, and radiofrequency ablation has not been reported. CASE SUMMARY: We describe 3 patients with symptomatic AF and interrupted IVC who underwent successful transhepatic left atrial access using ultrasound-guided placement of a 12-F hemostatic sheath. Pulmonary vein isolation and posterior wall isolation were performed with pulsed field ablation in all patients. Hepatic tract closure was achieved using absorbable gauze within the hepatic parenchyma. No access-related or procedural complications occurred, and all patients recovered uneventfully. DISCUSSION: This series demonstrates the feasibility of transhepatic AF ablation using a dual-energy lattice-tip catheter. Further studies are needed to define procedural safety and long-term outcomes.
