Portable fluoroscopic X-ray systems and traditional fixed angiographic systems: a comparison in the detection of coronary stenosis.
BACKGROUND
The ability to perform coronary angiography at the bedside has multiple applications.


METHODS
In this study, we compare the images obtained in 100 patients undergoing elective coronary angiography for coronary heart disease, with a portable X-ray imaging system (OEC 9600 Cardiac Version) to those obtained with a traditional fixed system (Siemens Coroskop C).


RESULTS
A complete concordance between the systems for lesion location, stenosis quantification, morphologic characterization, TI-MI flow and collaterals was found.


CONCLUSIONS
These findings demonstrate that a portable imaging system can produce high-quality images. The feasibility of performing a complete diagnostic procedure and the routine use of the system require more specific evaluation.
