Long-Term Follow-Up After Dual Transcatheter Valve-in-Valve Implantation Under VA-ECMO Support.
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
backgroundCardiogenic shock due to simultaneous degeneration of multiple prosthetic valves is rare and is associated with prohibitive surgical risk. CASE SUMMARY: A 73-year-old woman with 3 prior sternotomies presented with acute decompensated heart failure, which rapidly progressed to cardiogenic shock after atrial fibrillation. Multimodality imaging demonstrated severe dysfunction of both aortic and mitral bioprostheses, with biventricular dysfunction. Refractory shock necessitated venoarterial extracorporeal membrane oxygenation (ECMO). Given extreme surgical risk, a transcatheter strategy was pursued. Sequential transfemoral aortic and transseptal mitral valve-in-valve implantations were successfully performed under ECMO support. Hemodynamics improved immediately, allowing ECMO explantation. At the 3-year follow-up, both valves demonstrated durable function with sustained clinical recovery. DISCUSSION: The increasing integration of mechanical circulatory support with rapidly evolving transcatheter valve technologies is enabling a new paradigm of complex and high-risk structural heart interventions. TAKE-HOME MESSAGE: Dual transcatheter valve-in-valve implantation is feasible and effective in selected patients on mechanical circulatory support.
