Portable fluoroscopic X-ray systems and traditional fixed angiographic systems: a comparison in the detection of coronary stenosis.

ABSTRACT

INTRODUCTION: 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.
