Recently, portable C‐arm systems have been developed for cardiac studies. While these systems have been used at a number of centers on a small scale for procedures in the operating room, emergency room, or intensive care unit, there are no published data on the performance of the system under more demanding circumstances. Theoretically, a reliable portable C‐arm system could provide a low‐cost alternative to a fixed system in centers with limited resources, such as in developing countries. To test whether a portable C‐arm system could substitute for a permanent laboratory for cardiac catheterization and interventional procedures, we used a C‐arm system as our sole catheterization laboratory for a period of 3 months. The system's performance was compared to a comparable time period using a fixed catheterization laboratory system. The portable system was used to perform 222 procedures (36 interventional and 186 diagnostic), as compared to 236 procedures (30 interventional and 206 diagnostic) with the fixed lab during a comparable time period the preceding year. Although the image quality of the portable system was not as good as with the fixed laboratory, all procedures were performed successfully, with no difference in fluoroscopic time, radiation exposure to the patient, procedure related complications, or clinical restenosis at 1 year. However, radiation exposure to staff was greater, possibly due to the lack of shielding in the temporary lab and the need for the technician to remain close to the unit to set up views. Our results suggest that a portable C‐arm system, while subject to some limitations, can perform as a general catheterization laboratory for diagnostic and interventional procedures.
