Emergent TAV-in-TAV for Failed Bioprosthetic Valve With Severe Aortic Regurgitation Presenting as a Myocardial Infarction.
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
backgroundWe present an 82-year-old man with a history of coronary artery disease status after coronary artery bypass grafting, percutaneous coronary intervention, hypertension, and severe aortic stenosis status post transcatheter aortic valve replacement who presented to the emergency department with substernal chest pain and dyspnea. CASE SUMMARY: The patient's workup revealed ST-segment elevations in V DISCUSSION: Transcatheter aortic valve replacement is typically performed to treat aortic stenosis or regurgitation in stable patients, but in this case it was used to mitigate a patient's severe aortic regurgitation through a prior bioprosthetic valve because of his hemodynamic instability. TAKE-HOME MESSAGE: This case highlights the use of an emergent transcatheter aortic valve-in-valve bioprosthetic valve replacement to treat a patient with cardiogenic shock secondary to severe aortic insufficiency.
