Multimodality image fusion to guide peripheral artery chronic total arterial occlusion recanalization in a swine carotid artery occlusion model: unblinding the interventionalist.
Article in Catheterization and cardiovascular interventions : official journal of the Society for Cardiac Angiography & Interventions, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesTo demonstrate the feasibility of magnetic resonance imaging (MRI) to X-ray fluoroscopy (XRF) image fusion to guide peripheral artery chronic total occlusion (CTO) recanalization.
backgroundEndovascular peripheral artery CTO revascularization is minimally invasive, but challenging, because the occlusion is poorly visualized under XRF. Devices may steer out of the artery, which can lead to severe perforation. Merging preacquired MRI of the CTO to the live XRF display may permit upfront use of aggressive devices and improve procedural outcomes.
methodsSwine carotid artery CTOs were created using a balloon injury model. Up to 8 weeks later, MRI of the carotid arteries was acquired and segmented to create three-dimensional surface models, which were then registered onto live XRF. CTO recanalization was performed using incrementally aggressive CTO devices (group A) or an upfront aggressive directed laser approach (group B). Procedural success was defined as luminal or subintimal device position without severe perforation.
resultsIn this swine model, MRI to XRF fusion guidance resulted in a procedural success of 57% in group A and 100% in group B, which compared favorably to 33% using XRF alone. Fluoroscopy time was significantly less for group B (8.5 ± 2.6 min) compared to group A (48.7 ± 23.9 min), P < 0.01. Contrast dose used was similar between groups A and B.
conclusionsMRI to XRF fusion-guided peripheral artery CTO recanalization is feasible. Multimodality image fusion may permit upfront use of aggressive CTO devices with improved procedural outcomes compared to XRF-guided procedures.
