Transcatheter Aortic Valve Replacement in Severe Horizontal Heart With Acute Aortic Angulation.
Article in JACC. Case reports, 2025. 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 aortic valve replacement (TAVR) has become a first-line treatment for elderly patients with severe aortic stenosis since its first successful implementation in 2002. However, performing TAVR in patients with extreme horizontal heart orientation and acute aortic angulation is technically challenging and carries higher procedural risks. CASE SUMMARY: This case report describes a patient with severe aortic stenosis complicated by an extreme horizontal heart position and acute aortic angulation. Under the support of cardiopulmonary bypass (CPB), femoral artery long sheaths, and snare traction, the TAVR procedure was successfully completed. DISCUSSION: The success of this case provides valuable insights for managing complex TAVR procedures. TAKE-HOME MESSAGES: CPB provides critical hemodynamic support during TAVR in patients with extreme horizontal cardiac orientation, effectively preventing intraoperative circulatory collapse. Advancing a femoral artery long sheath combined with snare traction overcomes challenges when TAVR in cases of severe horizontal heart orientation and acute aortic angulation.
