Two-Staged Transcatheter Aortic Valve Replacement in Severely Calcified Sinotubular Junction.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveSevere sinotubular junction (STJ) calcification presents important challenges during transcatheter aortic valve implantation, including risk of aortic dissection or aortic root rupture and valve malposition. We describe a straightforward and reproducible two-stage balloon inflation technique with a balloon-expandable SAPIEN 3 valve to optimize precision and procedural safety in this difficult setting. TECHNIQUE: Step 1: Initial balloon inflation at 2 mL less than nominal volume to secure annular anchoring and limit radial force on the calcified STJ. Step 2: Balloon advanced 1-2 mm under fluoroscopy toward the inflow and inflated to the full nominal volume, completing valve deployment. PITFALLS: Inadequate anchoring may cause migration or embolization, underestimation of calcification can compromise expansion, and balloon overinflation may cause root injury.
conclusionThis staged inflation method anchors the valve, minimizes STJ stress, and provides a simple, reproducible strategy that may improve safety in anatomically complex patients.
