Coronary angiography using a portable super-C-arm imaging system in a district general hospital

Background: New generation portable super-C-arm imaging systems may offer an alternative means of performing coronary angiography at a lower cost compared with a fixed laboratory. We evaluated the use of one such system (GE-OEC 9800) in a district hospital setting. Methods: The demographics, procedu...

Description
Summary:Background: New generation portable super-C-arm imaging systems may offer an alternative means of performing coronary angiography at a lower cost compared with a fixed laboratory. We evaluated the use of one such system (GE-OEC 9800) in a district hospital setting. Methods: The demographics, procedure and screening times, emitted radiation dose and diagnoses of the first 200 consecutive patients were obtained from a prospective database. Comparison between the portable and fixed systems were made by analysing results from similar cohorts of patients who underwent angiography by the same operators. Image quality was assessed in 23 patients, by an independent cardiologist, comparing the GE-OEC 9800 angiograms with repeat images using a fixed laboratory Philips (HM 3000) system within 3 months of the first study. Results: The procedure time (mean (S.D.)) was 18.9 (0.8) min for the 200 cases. The screening time was 255 (15) s with an emitted radiation of 22.8 (1.4) Gy/cm 2. Comparison between the C-arm and fixed systems revealed significantly longer screening time (230.6 (14.6) vs. 157 (12.9) s, p
