Patient-specific registration of 3D CT angiography (CTA) with X-ray fluoroscopy for image fusion during transcatheter aortic valve implantation (TAVI) increases performance of the procedure.

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
objectivesThe aim of this study was to adapt patient-specifically a co-registration procedure for image fusion (IF) of a pre-interventional CT dataset with real-time X-ray (XR) fluoroscopy during transfemoral transcatheter aortic valve implantation (TAVI), enabling improved performance of the procedure.
backgroundThe ability to use 3D models of the respective anatomies to complement the anatomic information obtained by XR fluoroscopy and provide a greater degree of real-time anatomical guidance holds great potential for complex cardiac interventions, especially for TAVI procedures with cerebral protection.
methodsInitial registration of two datasets was performed during the femoral puncture and sheath introduction using routinely acquired arteriographies. On-time refinement of the co-registration was then performed during the on-going procedure avoiding additional angiograms for the co-registration. Performance of the method was evaluated quantitatively in terms of procedural characteristics and clinical events.
resultsSignificant reduction of the radiation dose [51 (42-55) vs. 64 (49-81) Gy cm
conclusionsIn this proof-of-concept study we have demonstrated a novel co-registration approach for IF during TAVI not requiring any additional CA or XR scan. We have evaluated its potential benefit with the strong focus on guiding the femoral puncture, placement of the double-filter cerebral embolic protection device, and deployment of the valve prosthesis. We achieved improved performance and safety of the procedure with the introduced approach.
