A Pilot Study on Novel Use of Color Doppler Imaging for Navigation of Wiring in Coronary Interventions.

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
objectiveTo test the Doppler guide wire (DGW) for navigation of the wire positioning by color Doppler ultrasound in the setting of percutaneous coronary intervention (PCI).
methodsAn acoustically active DGW was tested in a water tank before its in vivo use. A waveform generator was connected to the DGW, and a transducer scanned the DGW to visualize a Doppler shift signal between the vibrating piezoelectric crystal located at the DGW tip and Doppler signal from the transducer as a distinct, instantaneous color marker. An intracoronary injection was tested in four male domestic pigs using an open-chest setting. A Judkins left coronary guiding catheter was inserted into the ascending aorta via the right carotid artery under B-mode ultrasound guidance. The DGW with an infusion catheter or over-the-wire (OTW) balloon catheter was inserted into the guiding catheter. The color marker instantaneously defined the DGW tip and navigated the catheter into the left anterior descending artery (LAD).
resultsThe tip of the DGW was visualized within the guiding catheter by a distinct color marker and helped to engage the guiding catheter to the left main orifice. The DGW with an infusion or OTW balloon catheter was inserted into the LAD. We confirmed that the catheter was positioned in the proximal LAD by the colored territory perfused by an injected indigo carmine solution.
conclusionUltrasound navigation using acoustically active DGW was feasible. Our pilot study introduces a new concept of color Doppler-navigated wire positioning in the coronary artery in the setting of PCI.
