IVUS-Guided Pulmonary Artery Hemodynamic Sensor Implantation: A Novel Contrast-Sparing Strategy.
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
objectiveThis case report describes a novel insertion technique of a hemodynamic sensor (CardioMEMS), avoiding the need for intravenous contrast in patients with baseline renal dysfunction. KEY STEPS: Intravascular ultrasound (IVUS) was employed to both visualize and direct the placement of the CardioMEMS. IVUS, along with fluoroscopy, were used to identify the left pulmonary artery as well as guide and confirm sensor placement. POTENTIAL PITFALLS: The use of IVUS requires the operator to be familiar with identifying the appropriate target of the left pulmonary artery on ultrasound imaging. In addition, the introduction of IVUS in complex anatomy or a heavily calcified vessel may increase the risk of complications, including vessel perforation, dissection, and thrombosis. TAKE-HOME MESSAGES: IVUS is a feasible technique for CardioMEMS placement, minimizing the need for contrast. This is of particular importance in patients with heart failure and renal dysfunction, placing them at high risk for progression to renal failure.
