Successful Long-Term Outflow Graft Patency Restoration With a Stent-Graft Implantation in an LVAD Recipient.
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
backgroundOwing to a shortage of heart donors and the increasing prevalence of end-stage heart failure, left ventricular assist device (LVAD) therapy is expanding. LVAD complications, including outflow graft (OG) obstruction, significantly affect patient prognosis. CASE SUMMARY: We report a 70-year-old man with ischemic heart failure 2.5 years after HeartMate 3 implantation. At admission, exertion dyspnea, peripheral edema, and occasional LVAD alarms were observed, which subsequently intensified. Multimodality imaging revealed OG obstruction. OG stent-graft implantation was performed, but after patency restoration, a critical narrowing appeared, which was successfully managed with balloon angioplasty. The LVAD function and 2.5-year follow-up results were uneventful. DISCUSSION: Percutaneous OG obstruction management in HeartMate 3 patients has been described by a few investigators, mostly with midterm follow-up. TAKE-HOME MESSAGES: OG obstruction may require multimodality imaging and management, including multispecialty procedures. Stent-graft implantation and OG ballooning appear to be feasible treatment options for OG obstruction, with a good long-term outcomes.
